Resumen
A field experiment was carried out during 2000-01 to 2002-03, at Kendrapara, to study the effect of nutrient management on yield, nutrient uptake and economics of white jute (Corchorus capsularis L.)-rice (Oryza sativa L.) cropping system in rainfed medium land. Application of 60 kg N, 30 kg P20, and 30 kg K,O/ha (recommended dose for white jute) along with MgSO,. 7H20 @ 10 kglha + lime (0.5 lime requirement ) to jute crop recorded the highest fibre yield (2.28 tonneslha), and maximum grain yield (3.89 tonneslha) of succeeding rice crop were ob- tained with a fertilizer dose of 60 kg N, 30 kg P20, and 30 kg K20/ha in the system. This resulted in an increased yield of 26.7% in jute fibre and 10.2% of rice grain over the recommended fertilizer dose in both the crops. The nutrient uptake (N,P,K, Ca, Mg and S) of individual crop and the system increased owing to NPK + 10 kg MgSO,. 7 H20 + lime (0.5 lime requirement) in jute, followed by rice with only recommended fertilizer dose in comparison to other treatments. The maximum net returns (Rs 22,628lha) and the highest benefit : cost ratio (1.71) were re- corded with the recommended NPK to both crops along with MgSO, and lime to jute only in jute-rice cropping system under rainfed condition.

Resumen
In the last few decades, use of jute has declined due to wider popularity of polyethylene and other synthetic packaging materials across the world. As a result there has been decline and fluctuations in the demand of raw jute and farmers are the subject of this fluctuation in India. Jute is one of the major cash crops in Assam and the state ranked third in terms of its production. However, presently Jute has become less lucrative crop in the crop portfolio of the farmers of Assam. Due to growing ecological awareness, natural fibers including jute are regaining their importance in the contemporary time. This paper tries to project diversification strategy to ensure economic sustainability of the jute growers in Assam. Constraints of the jute growers are also taken into consideration. The study is based on both primary as well as secondary data. Analysis of growers' constraints and feasibility model are the applied outcome of the paper.

Resumen
Aim: Assessment of energy input output relationship, greenhouse gases emission and carbon footprint of diversified jute-rice cropping systems under different nutrients and crop residue management practices. Methodology: The inventory was prepared for all inputs required for crop cultivation and outputs of crops in cropping systems. These inputs and outputs were converted into energy by multiplying with energy equivalent coefficient and CO2 emission coefficient following standard procedure. Results: Jute-rice-baby corn cropping system recorded significantly higher net energy (324 GJ ha-1) and energy use efficiency (8.02). Among different nutrient and crop management (NCRM) practices, significantly higher energy output (336.9 GJ ha-1) and net energy (291.4 GJ ha-1) recorded 100% NPK with crop residue. The highest carbon footprint recorded with rice-rice (0.44 kg COe kg-1 economic yield) and the lowestwith jute-rice-pea (0.29 kg COe kg-1 economic yield) cropping system. Among different NCRM practices, higher carbon footprint was (0.38 kg COe kg-1 economic yield) recorded with 100% NPK with crop residue. Interpretation: The energy efficient and low input required cropping systems which include legume crops like garden pea and mungbean should be considered for cultivation for diversifying the existing rice-rice cropping system in Eastern India.

Resumen
Crop selections and rotations are very important in optimising land and labour productivities, enhancing higher cropping intensities, producing better crop yield. A land suitability analysis system based on the analytical hierarchy process (AHP) technique coupled with the Geographic Information System (GIS) software environment can be a unique tool for better crop selection. The AHP-GIS technique was used in land suitability analysis in crop rotation decisions, for rice-jute (Kharif season) and potato-lentil (Rabi season) crops in the Hooghly District, West Bengal, India. The study area covering 291 ha was classified based on eight major soil nutrient levels with 70 randomly selected plots for soil sampling and analysis. The soil nutrient variability was examined with descriptive statistics followed by best semivariogram-based model selection for kriging interpolation in the ‘R’ software environment. The pairwise comparison matrix based ranking of parameters and giving weights was carried out considering the importance of each parameter for specific crops. The total area, being under the major rice-potato belt, could be classified from the suitability view point to the ‘highly suitable’(S1) class occupying 29.2%, and ‘not suitable’ (N) class; 4.5% for rice, about 6.5% of land is ‘highly suitable’ (S1), ‘and nearly 2.1% area is ‘not suitable’ (N) for jute; and 21.3% is ‘highly suitable’ (S1) for potato and 12.4% for lentil crops. The yield maps showed nearly 75% and 90% of the area for rice and potato crops, respectively, gave sound crop yield. Furthermore, the GIS platform was used for crop rotation analysis to spread multiple seasons ensuring better crop management in long run. Overall, 25% of the rice crop area for jute in Kharif and 8% of potato crop area for lentil in the Rabi season were recommended as replacements.

Resumen
Jute ( Hibiscus cannabinus L. & H. sabdariffa L.) and allied fibres (mesta, sunnhemp, ramie, sisal and flax) play an important role in Indian economy. Raw jute (jute and mesta) farming, industry and trade provide liveli- hood support to about 5 million people in India and is grown in an area of about 1.0 million ha. Despite a two- fold increase in the productivity of jute since independence, the area is stagnant for last two decades. The acre- age of other fibre crops like ramie and sisal has not increased substantially though ramie and sisal fibres are costlier than raw jute, sunnhemp and cotton. The increased cost of cultivation of jute and the fluctuating market price often affects the farmers. So to enhance the profitability of jute and allied fibre farming, we have to intro- duce high value crops as components of jute-based cropping systems besides extending their cultivation to non-traditional areas. Ramie has shown a good growth and yield at Nilgiri hills, Goa, Maharastra while sisal has a great potential in the dry areas like western Orissa, Madhya Pradesh, Jharkhand. Diversification and value addition to the end products is needed as there is wide scope in the global market and the part of the ad- ditional profit must reach the farmers to motivate them. Jute ( Corchorus capsularis L. & C. olitorius L.) is the main commercial crop of the eastern and north eastern India providing livelihood security to about 5.0 million people (4.0 m farmers, 0.25 m mill workers and 0.50 m people engaged in jute based ancillary sectors). It is grown in an area of little over 0.8 m ha, producing nearly 10 million bales (1 bale 180 kg.) of fibre, which is about 40% of the worlds' production. Mesta is grown in an area of 0.15 m ha with a production of 1.0 m bales. The major jute growing states are West Bengal, Bihar, Assam, Orissa, Uttar Pradesh, Meghalaya and Tripura while mesta is mostly cultivated in Andhra Pradesh, Maharastra, Orissa and Bihar. Sunnhemp ( Crotalar ia juncea L.) is cultivated mostly in Bihar, Uttar Pradesh, Madhya Pradesh, Rajasthan, Maharastra and Tamil Nadu.

Resumen
Jute being a C3 crop, it cannot compete with the C4 weeds at its early stage and about 40 per cent of total cost of cultivation of jute goes in weeding process alone. Upsurge of new weed flora, labour scarcity, herbicidal resistance and its environmental concern and slow mechanization urged us to control weeds in jute field by its smothering effect. Experiments were conducted at ICAR-CRIJAF, Barrackpore, WB in 2018-19, 2019-20 & 2020-21 with jute (cv. NJ-7010) by its high density broadcast sowing (seed rate @ 6.0 to 7.5 kg/ha). Irrigation, fertiliser and pesticides requirements were standardised for this purpose. Only 45 cm wide strip (5% of total area) around the jute field was manually weeded to prevent seed formation of weeds in boarder areas. The dense jute canopy (200-348 /m2) of 29 cm mean height at 25- DAS reduced the incident light at jute base by 90-95 per cent and dominated all C4 weeds. In this 1st year it reduced the grass, broadleaf, sedges weed population (max 52 m2) and weed bio mass by 98, 98.5, 64.5 and 91.65 per cent respectively over manual weeding twice. Next year at 25 DAS it reduced the grass sedges weed population by 70, and 62% respectively over initial status. In third year most of the grass (507/m2), broadleaved (504/m2) and sedges (52/m2) were smothered by its cover crop effect at early stage (25 DAS). Remaining weeds were rudimentary, incapable of producing seeds. In consecutive three years out, of 20.7 lakh (40 DAS), 26.8 (25 DAS), 34.8 l lakh jute plants/ha (15 DAS), only 3.3, 6.3 and 7.64 lakhs jute plants/ha i.e., 16, 23.5 and 22 % of total initial population were found effective and harvested (125 to135 DAS). The improved experiment of 2nd and 3rd year produced 3.837 & 3.798 t fibre/ha respectively which were at par with manual weeding, chemical herbicide and mechanical weed control process. It eliminated weeding and thinning processes and consumed only 195 and 276 man days/ha from sowing to fibre extraction over conventional method (340 to 365 man days/ha). It saved 89-145 man days/ha (Rs.22500 to 36250/ha). Mesta (Hibiscus cannabinus) also showed similar response as smother crop (2018-19). Pretilachlor 50 EC @ 0.9 l a.i/ha (POE, 7 days) was found effective for weed control in zero till piara crop. Weed smothering by intercropping green garm with jute (1:1)/mixed cropping were also found economic, produced 0.8-1.0 t pulse grain/ha along with 2.7-2.9 t jute fibre and 1.7 to 2 tonnes nutrogen rich (2.35%) pulse waste per ha.. Pre emergence herbicide Pretilachlor 50 EC and Ipfencarbazone 22.8 %SC were found effective for jute. This weed smothering merit of jute can be used for reducing weed seeds in seed bank growing in repeated flushes, it can also be used as cover crops for different crops which will seqester a lot of carbon to soil also. Weed smothering by high density broadcast jute sowing will eliminate dependence on herbicides, mechanical and manual weeding and make jute farming more remunerative and sustainable in nature.

Resumen
Crop diversity through residue incorporation is the most important method for sustaining soil health. A field study was conducted over five consecutive years (2012–2017) to see the impact of residue incorporartions in Inceptisol of eastern India. The main plot treatments had five cropping systems (CS), namely, fallow−rice−rice (FRR), jute−rice−wheat (JRW), jute−rice−baby corn (JRBc), jute−rice−vegetable pea (JRGp), jute−rice−mustard−mungbean/green gram (JRMMu), which cinsisted of four sub-plots with varied nutrient and crop residue management (NCRM) levels, namely crops with no residue +75% of the recommended dose of fertilizers (RDF) (F1R0), crops with the residue of the previous crops +75% RDF (F1R1), crops with no resiude +100% RDF (F2R0), and crops with residue +100% RDF (F2R1). The highest system productivity was obtained for JRBc (15.3 Mg·ha−1), followed by JRGp (8.81 Mg·ha−1) and JRMMu (7.61 Mg·ha−1); however, the highest sustainability index was found with the JRGp cropping system (0.88), followed by JRMMu (0.82). Among the NCRMs, the highest productivity (8.78 Mg·ha−1) and sustainability index (0.83) were recorded in F2R1. Five soil parameters, namely, bulk density, available K, urease activity, dehydrogenase activity, and soil microbial biomass carbon (SMBC), were used in the minimum data-set (MDS) for the calculation of the soil quality index (SQI). The best attainment of SQI was found in the JRGp system (0.63), closely followed by the JRMMu (0.61) cropping system.

Resumen
Site specific calibration of crop coefficient (Kc) values is essential for irrigation scheduling of any crop. In order to determine the values of Kc for jute, an experiment was conducted at the Irrigation and Water Management Division of Bangladesh Agricultural Research Institute (BARI), Gazipur. An improved jute variety BJRI Tosa-2 (O-9897) was used in this experiment. The study examined growth and yield of the jute in terms of four irrigation treatments distributed over 7-28 days intervals. The treatments were so designed that drainage was allowed between the consecutive irrigations. Irrigation at 14days interval produced the highest dry fiber yield (3.93 t/ha) and was considered to be suitable for estimating seasonal crop evapotranspiration and Kc values. The seasonal crop ET was 549.13 mm under this treatment. The Kc values of jute at initial, development, mid-season and late season stages were found to be 0.72, 1.39, 1.26 and 0.46, respectively. As there is no FAO-recommended Kc value for this crop, this locally calibrated values can be used for similar climatic conditions of Bangladesh and elsewhere. Therefore, based on Kc value, it can be recommended that jute can be irrigated by equal amount of water needed for crop evapotranspiration (ETc) for different growth stages (141.05, 142.57, 167.34, and 84.30 mm) to get maximum dry fiber yield.

Resumen
West Bengal is a key producer of raw jute fiber in the country. Identifying and managing dry spells during the jute growing period is crucial, necessitating contingency crop planning for enhanced productivity. Keeping this view in mind, standardized precipitation index (SPI) was calculated over five locations, representing five different districts of southern West Bengal. These locations are Barrackpore (North 24 Parganas District), Panagarh (Burdwan District), Bagati (Hooghly District), Krishnanagar (Nadia District) and Uluberia (Howrah District). This rainfall dependent dryness index (SPI) was calculated in 1 month and 3 months interval to identify short term dryness as well as mid-term dryness, applicable for seasonal crops. The trend analysis of the SPI values indicated that North 24 Parganas and Nadia experienced increased dryness during vegetative phase of Jute. Nadia district showed a significant increase in both short term and long-term dryness. The yield reduction index is well correlated with SPI values in all the study locations except Howrah. Arrangement of irrigation during the early stages of Jute can help the crop to cope up with the break of monsoon in this region

Resumen
MicroRNAs play a pivotal role in regulating a broad range of biological processes, acting by cleaving mRNAs or by translational repression. A group of plant microRNAs are evolutionarily conserved; however, others are expressed in a species-specific manner. Jute is an agroeconomically important fibre crop; nonetheless, no practical information is available for microRNAs in jute to date. In this study, Illumina sequencing revealed a total of 227 known microRNAs and 17 potential novel microRNA candidates in jute, of which 164 belong to 23 conserved families and the remaining 63 belong to 58 nonconserved families. Among a total of 81 identified microRNA families, 116 potential target genes were predicted for 39 families and 11 targets were predicted for 4 among the 17 identified novel microRNAs. For understanding better the functions of microRNAs, target genes were analyzed by Gene Ontology and their pathways illustrated by KEGG pathway analyses. The presence of microRNAs identified in jute was validated by stem-loop RT-PCR followed by end point PCR and qPCR for randomly selected 20 known and novel microRNAs. This study exhaustively identifies microRNAs and their target genes in jute which will ultimately pave the way for understanding their role in this crop and other crops.

Resumen
Jute is well-known for its distinctive versatility in Bangladesh and comes in first place in terms of output, which illustrates the jute crop's dual character of quantity and quality. This review discusses the significance of the jute crop and the advantages of nutrient management techniques in the jute and allied fibre crops (JAF), which increase output, fecundity, and output to fulfill the nation’s potential fibre requirements. Due to the demand for JAF fibres in the production of various goods, fibres make a significant economic contribution to Bangladesh. It not only gives the rural population a job, but it also generates cash for the area. If integrated nutrient management strategies are used, it will be simple to meet future demand for jute-based products while still preserving agriculture. Res. Agric. Livest. Fish.

Resumen
Sustainable crop production through intensification of crops in cropping system is a global important issue to ensure food security, human and soil nutrition, poverty alleviation, and job opportunity creation. Rabi crop (mustard/lentil)-Jute cropping system and transplanted (T) Aman rice-Boro (T. Boro) rice cropping system are the traditional cropping systems in Low Ganges River Floodplain (AEZ-12) soils of Bangladesh. Jute and T. Aman rice are usually cultivated in summer season, but the T. Boro rice is cultivated in winter season. Jute and T. Boro rice are highly cost consuming crops due to need more irrigation, labors and fertilizer etc. T. Boro rice and jute are easily replaced by a short duration of mungbean and T. Aus rice in the existing cropping system. Hence field trial on different cropping systems were conducted in Regional pulses Research Station (RPRS), BARI, Madaripur and the adjacent farmers’ field of RPRS during 2013-14 and 2014-15 to compare and evaluate the four crop-based cropping systems with existing cropping systems based on system productivity, nutrient uptake and balance, profitability and sustaining soil fertility. The experiment was planned with six treatments comprising three of four crop-based cropping systems and three existing traditional cropping systems. The treatments were FCS1 (Mustard-Mungbean-T. Aus rice-T. Aman rice), FCS2 (Lentil-Mungbean-T. Aus rice-T. Aman rice), FCS3 (Fieldpea-Mungbean-T. Aus rice-T. Aman rice), ECS1 (Mustard-Jute), ECS2 (Lentil-Jute) and ECS3 (T. Boro rice-T. Aman rice) following randomized complete block design with three dispersed replications. As per results, the greater system productivity (rice equivalent yield: 16368 kg ha-1) was significantly obtained from FCS2 than the other system treatments. The FCS2 treatment exhibited the highest percent increment of rice equivalent yield (REY) over existing cropping system ECS1, ECS2 and ECS3 was 322%, 234% and 84.1%, respectively. Also higher %REY increment of FCS2 was 20.3% and 14.5% over the other four crop-based cropping systems FCS1 and FCS3. Production efficiency was highest in same FCS2 treatment. Land use efficiency increment was observed higher in Fieldpea-Mungbean-T. Aus rice-T. Aman rice cropping system. Total nutrient (N, P, K, S, Zn, B) uptakes and nutrient balance were positively influenced among the cropping systems, but both were showed inconsistent trends. The result of postharvest soil exhibited higher organic carbon (8.78 g kg-1) and total N content (0.74 g kg-1) was in FCS2 treatment. The FCS2 was also economically profitable and viable as compared to other cropping systems due to having higher gross return, gross margin and benefit cost ratio (2.48). The FCS3 was the second economically profitable and viable system as compared to other cropping systems. Intensification and diversification of crops from two to four crop-based cropping systems lead to increase the system productivity, profitability, and sustaining soil fertility. Results suggest that lentil-Mungbean-T. Aus rice-T. Aman rice followed by Fieldpea-Mungbean-T. Aus rice-T. Aman rice cropping system can practice in the experimental area for positive change the farmers’ livelihoods. This finding may be potential for the area where there is no practice of improving four crop-based cropping systems.

Resumen
Rainfall, its distribution along with distribution of temperature. relative humidity (RH), bright sunshine hours (SSH) suggest the possible growing season and crop performance in a given area. Field experiments on five economically feasible, sustainable, rainfed crop sequences viz. fallow (i.e. no crop) – rice-lentil, jute-rice-lentil, direct seeded rice-rice-lentil, mungbean-rice-lentil and sesame-rice-lentil were conducted at Kalyani Farm, W.B., during 1989-91. Mean monthly meteorological parameters viz. rainfall, potential evapotranspiration (PET), SSH, temperature (max. and min.) and RH (at 0700 and 1400 hrs LMT) were obtained from selected agrometeorological observatories (viz. Chinsurah, Haringhata and Barrackpore), adjacent to the Kalyani Farm located in Gangetic alluvial region. The relative yield performance of crops and sequences as influenced by meteorological parameters were studied. In Gangetic alluvial region early rain, moderate to high temperature with high RH during April/May resulted in good pre-kharif crop establishment. Heavy, well distributed precipitation during monsoon months along with moderate temperature and very high RH showed scope for rainfed transplanted kharif rice as the pivot of crop rotation. Kharif rice yields were high especially after jute or mungbean. Profile stored residual moisture along with low rainfall, low temperature and high RH during rabi season resulted in good performance of lentil. Among the five sequences studied, performance of' jute-rice-lentil and mungbean-rice-lentil were the best with sustainable production and net return.

Resumen
The stage-specific life table and nutritional ecology of a Spilarctia obliqua (Walker) along with respective economic thresholds (ETs) on four different crops such as sesame (Sesamum indicum), castor (Ricinus communis), jute (Corchorus capsularis) and sunflower (Helianthus annuus) were studied during 2020-2022. The feeding and population dynamics of S. obliqua were significantly affected by the hosts in terms of host suitability or susceptibility (sunflower>jute>castor>sesame). The ET of S. obliqua on sesame (40.59±2.12 pests m-2 area) was significantly (F3,8=4.72, P=0.031) higher than the other crops (sunflower<jute<castor). Subsequently, the three most suitable hosts (sunflower> jute>castor) were tested in a multi trap cropping system for sesame as main crop in a specific pattern depending on respective susceptibility. Data from the model trap cropping (without pesticide) supported minimum infestation of S. obliqua and other pests along with more predators on sesame with higher benefit cost ratio (BCR) and more (11.82%) carbon sequestration (CS) in same area relative to monoculture (with pesticide) of sesame. It supports pesticide free high production and better CS than sole culture of sesame for climate smart agriculture.

Resumen
The jute yellow mite Polyphagotarsonemus latus constitutes one of the major pests of jute crop in Bangladesh. The objective of this work was to investigation on the natural enemies of jute yellow mite. The investigation on the natural enemies of jute yellow mite were studied in the laboratory of Bangladesh Jute Research Institute during March 2011 to September 2013. As many as six predators of jute yellow mite viz, Predatory mite, Thrips, Minute pirate bug, Lady bird beetle, Mirid bug and Spider were collected and identified. The predation rate of the predatory mite Amblyseius sp. showed an average of 8.8 jute yellow mite per hour in laboratory condition. Predatory mite reached the peak on the 20th June. The highest population was 25 predatory mite/25 leaves. The population of predatory mite declined sharply in the 1st week of July. The nymph and adult of Scolothrips consumed an average of 15.4 and 20.10 yellow mite per hour. Scolothrips sp reached its peak population on 30th June and declined occurred in the 1st week of July. Both nymph and adult stage of Orius sp. predate 24.5 and 21 jute yellow mite respectively. The highest number of Minute pirate bug 20 was recorded at 30th June. Both the grubs and adults of lady bird beetle predate on all the stage of yellow mite. Grub was found as voracious feeder showing a predation efficiency of 35 per hour. The highest and lowest number of Ladybird beetle was recorded on 25th June and 5th May respectively. The highest 15 Mirid bug was recorded at 30th June. An unidentified species of spider was found to consume yellow mite.

Resumen
Agricultural crop production was affected worldwide due to the variability of weather causing floods or droughts. In climate change impacts, flood becomes the most devastating in deltaic regions due to the inundation of crops within a short period of time. Therefore, the aim of this study was to propose climate-adaptive crops that are suitable for the flood inundation in risk-prone areas of Bangladesh. The research area included two districts adjacent to the Jamuna River in Bangladesh, covering an area of 5489 km2, and these districts were classified as highly to moderately vulnerable due to inundation by flood water during the seasonal monsoon time. In this study, first, an inundation vulnerability map was prepared from the multicriteria analysis by applying a fuzzy expert system in the GIS environment using satellite remote sensing datasets. Among the analyzed area, 42.3% was found to be highly to moderately vulnerable, 42.1% was marginally vulnerable and 15.6% was not vulnerable to inundation. Second, the most vulnerable areas for flooding were identified from the previous major flood events and cropping practices based on the crop calendar. Based on the crop adaptation suitability analysis, two cash crops, sugarcane and jute, were recommended for cultivation during major flooding durations. Finally, a land suitability analysis was conducted through multicriteria analysis applying a fuzzy expert system. According to our analysis, 28.6% of the land was highly suitable, 27.9% was moderately suitable, 19.7% was marginally suitable and 23.6% of the land was not suitable for sugarcane and jute cultivation in the vulnerable areas. The inundation vulnerability and suitability analysis proposed two crops, sugarcane and jute, as potential candidates for climate-adaptive selection in risk-prone areas.

Resumen
To classify rice crops, the paper applies deep learning to agricultural crop images to classify rice crops. The collection includes images of wheat, rice, sugarcane, jute, and maize. We improved variety by horizontally flipping, rotating, and shifting rice image data sets. A CNN structure classifies rice and non-rice crops. The model has 100% accuracy on training and testing datasets; however, the classification report shows label imbalance problems for precision, recall, and F-score. Deep learning can help classify crops as well as make decisions in agriculture based on research. The study recommends more studies and improvements to enhance model performance and address dataset concerns. The research advances agricultural technology and emphasizes machine learning for crop management and production.

Resumen
Minimum soil disturbance and increased crop residue retention practices are promising options to enhance soil organic matter, nutrient concentration and crop yield. However, the potentials of the practices in improving soil properties, increasing crop yield and in ensuring economic return have not been tested in the monsoon rice (Oryza sativa L.)-lentil (Lens culinaris L.)/wheat (Triticum aestivum L.)-jute (Corchorus culinaris L.) cropping systems on seasonally flooded lowlands of the Eastern Gangetic Plain of South Asia. A field trial for consecutive three years was conducted in the Gangetic Plains of Bangladesh to evaluate the effects of zero tillage (ZT), strip-tillage (ST), bed planting (BP) and conventional tillage (CT) with two residue retention levels (RL—a low level similar to current farmers’ practice and RH—increased retention) on soil properties, yield and economic return. Between rice and jute crops, lentil was grown for the 1st and 2nd years and wheat for the 3rd year during the dry winter season. The ST and BP performed better than the CT and ZT in terms of yield of rice and lentil, whereas ST and ZT performed better than other practices in the case of jute. Higher residue retention (RH) increased crop yield for all the years. The highest rice equivalent yield (sum of 3 crop yields, expressed as rice yield) and the greatest benefit-cost ratio (BCR) were recorded with ST and RH. The increased yield in the ST was associated with reduced soil bulk density (BD), while ST with RH increased soil water (SW) and decreased penetration resistance (PR) of soil. Compared to CT, minimum soil disturbance of ZT and ST increased soil organic matter (SOM) stock by 24% and 23%, respectively; total nitrogen (TN) by 23.5% and 18.4%, respectively; extractable sulphur (S) by 21% and 18%, respectively; whereas Zinc (Zn) concentrations increased by 53% and 47%, respectively, in the upper 0–5 cm soil depth. Accumulation of extractable P, S and Zn in the 0–5 cm depth of soil followed the sequence as ZT > ST > BP > CT practice. The higher amount of residue retention significantly increased SOM, TN and extractable P, K, S and Zn concentrations at 0–5 cm and 5–10 cm soil depths. The 3-year study suggests that ST with RH is a potential crop management approach for the seasonally flooded rice-lentil/wheat-jute cropping systems to enhance soil nutrients status, crop yield and farm economy.

Resumen
Area and production of raw jute has decreased, though there is a high demand of raw jute in the country. In order to assess production constraints, a survey was carried out in 2005/06 in Jhapa, Morang and Sunsari districts. The study revealed that unstable or low price of raw jute, unavailability of quality jute seed, limited irrigation water at sowing period, diseases complex (wilt), labor shortage during peak season, weed problem, lack of retting water/retting pond were the main constraints in jute production and processing. The study indicates that the maximum production cost has involved in fiber extraction (16.9%) and weeding (16.33%). Jute productivity ranged from 1788 to 2260 kg per hectare. JRO-524 variety of jute has been widely grown across the region due to its wider adaptability, high yield potential and quality fiber. Jute area has been replaced by sugarcane due to its high yield potential and high profit margin. It is observed that the cost of production of jute is high as compared to other crops in the season. Average cost of production of fiber was estimated to be Rs.1563/quintal. For the promotion of jute cultivation in the eastern Terai, it would be better to provide subsidies on seeds and fertilizer to jute growers as practiced in neighboring countries thereby profit margin becomes high and will encourage growers in producing more raw jute within the country for the fulfillment of raw jute requirement of local jute industries. Cost effective technologies have to be developed in jute production and processing aspects for lowering the production cost and increasing the profit margin. Popular genotypes JRO- 524 which was widely adopted needs to be recommended officially for the general cultivation in this region. Being an eco-friendly crop, promotion is required to adapt climate change effect and maintaining the soil properties in jute growing areas.

Resumen
Jute is an important crop that contributes a pivotal role in the economy and supports the livelihoods of the farmers of the Northern part of West Bengal. However, farmers in the region are gradually shifting away from traditional jute cultivation to adopting maize as their preference and the study investigated the factors influencing transformation. Responses were collected from 60 farmers of Chopra Block using a structured interview schedule during the peak season of maize cultivation in 2019. Principal Component Analysis was used to extract significant factors explaining the motives behind farmers’ preference for maize over jute crops. The study envisages that the factors including lack of capital, remunerative market price, high labor costs, poor soil quality and inadequate irrigation water, unavailability of improved seed varieties, high input costs, and inadequate market facilities are the key factors for discouragement of cultivation of jute. The government should develop some supportive infrastructure like providing high-quality maize seeds, conducting awareness programs to educate the farmers about the benefits and byproducts of maize, and offering knowledge about export and import markets. Capacity building and extension approaches can aid the transition and foster positive contributions to the agricultural sector of the locality.

Resumen
Plant density is very important growth and yield contributing character of different crops. An experiment was conducted at Jute Agriculture Experimental Station, Bangladesh Jute Research Institute, Jagir, Manikganj to select suitable seed rate for leaf and seed yield of jute as vegetable. Six different seed rate i.e., T1=4.17, T2=8.33, T3=12.5, T4=16.67, T5=20.83 and T6=25.00 kg/ha were used as experimental treatment. Results revealed that the highest leaf number (14.13), leaf fresh weight (10.9g) and leaf dry weight (2.03g) was recorded in T3 treatment whereas the highest capsule number (375), number of seed per capsule (32) and seed yield per plant (15.16g) was found in T2 treatment. Days to seed maturity was minimum (85 days) in T2 treatment. It might be concluded that considering as a vegetable crop 12.5 kg/ha rate is the best seed rate for vegetative yield.

Resumen
SUMMARYThe implications of a novel system of seed production for tossa jute (Corchorus olitorius), involving late sowing and intercropping with vegetables, were studied in 1989 and 1990. The greatest jute seed yield was obtained from jute-radish intercropping, where radish yielded 12–13 t ha−1 roots and gave the highest average gross margin, although jute-amaranthus intercropping performed marginally better in 1989. This system of husbandry yielded 3–4 t ha−1 of jute stick for fuelwood, which is of great value to rural households, and proved to be a viable means of producing jute seed, vegetables and fuel.

Resumen
Jute is a rapid growing agricultural fiber crop and renewable source of biomass. The study was conducted to evaluate different jute mutants against insect and mite pests with associated natural enemies. Results revealed that 8 insect and mite pests and 8 natural enemies were recorded from coastal jute ecosystem. Jute hairy caterpillar and yellow mite were found to be the most damaging pests in jute field. Significantly the lowest per cent plant infestation per 5 rows was recorded in mutant BJC-214 (14.37) followed by BJC-7370 (14.81) and the highest per cent plant infestation (30.77) was found in mutant VM-1. Significantly the lowest per cent leaf infestation was in mutant HC-3 (25.40) followed by HC-95 (31.08) while the highest per cent leaf infestation per plant was recorded in mutant BJC-83 (46.30). In case of leaf area damage, the lowest per cent was observed in mutant HC-3 (9) followed by CVL-1 (10) and the highest was in mutant CVE-3 (45) followed by mutant 0-72 (30). Among different mutants, HC-3, CVL-1 and BJC-214 were found to be less infested by jute hairy caterpillar and these mutants could be used for multilocational trial for final recommendation as the tolerant mutants.

Resumen
The study aims to examine the utilization of crop residues of 458 farm households covering four districts in Bangladesh. Primary data were collected during October to December 2012 through field survey following purposive sampling. The evidence showed that the average age of the respondents were 40.23 years with an average family size of 4.84. About 37.12% respondents had above primary level of education and 81% respondents were engaged primarily in agriculture. The average farm size was found to be 2.61 acre. The annual household income was found BDT 215,584 of which 75 and 25% came from agriculture and non-agriculture sources, respectively. The study areas were mostly dominated by rice based cropping systems. Among the crop, rice alone contributed 83.14% of the total cultivated land followed by vegetables (41.76%), pulses (39.08%) and jute with cropping intensities ranges from 153.16 to 282.12%. The whole retention of boro rice was found higher than aman rice and oilseeds and maize were found higher than all crops. No retention of crop residues was found in case of jute and pulses. It was indicated that the retention rate varied crop to crop as well as location to location. The distance had also another major factor on the retention of crop residues. The households were benefited from retention of crop residues by improving soil health, add soil nutrients, improving soil structure and increasing water conservation to the field. The crop residues were mostly used for animal feed followed by cooking fuel and add organic matter to the field. The used cooking fuel come from their own fuel wood (about 14-53%), own crop residues (about 10-25%) and from cowdung (about 4-22%), respectively. The sources of animal feed was found from own crops (about 3- 52%), own crop residues (about 16-18%) and from green grass (about 6-24%), respectively. The constraints to retention crop residues and uses were the lack of proper method of harvesting, transporting them to the house, deficit labor and uneconomic. Finally, the study suggests for conducting training on appropriate methods of harvesting, processing of retention crop residues and improvement of transportation of harvested crop at home properly.DOI: http://dx.doi.org/10.3329/pa.v23i1-2.16575Progress.

Resumen
Conservation agriculture (CA) with appropriate nutrient management can help increase crop production, improve soil health and bring economic return. An experiment was conducted at farmer’s field of Rajbari district under Low Ganges River Floodplain (AEZ-12) during 2017-2018 to evaluate the effects of tillage and nutrient management on the system productivity and profitability in the jute - T. Aman rice- onion cropping system. Strip tillage (ST) for jute, non-puddling for T. Aman rice and one pass minimum tillage (MT) for onion was contrasted with conventional crop establishment practice (CT). Four different nutrient management practices were NM1: farmer’s practice (FP), NM2: soil test based (STB) fertilizer, NM3:25% extra of STB and NM4: organic amendments (20 % nutrients from cowdung). The experiment was laid out in a split-plot design with three replications by assigning tillage practices in main plots and nutrient management in sub-plots. The yield attributes of jute, T. Aman rice and onion responded similarly to tillage practices. On the other hand, the system productivity and yield of component crops varied due to different nutrient management practices (p<0.05). The highest fibre yield of jute (3.64 t ha-1) was obtained in 25% extra of STB fertilizer dose; the highest T. Aman yield (6.02 t ha-1) and the highest onion bulb yield (16.0 t ha-1) in 20 % organic nutrient management, followed by25 % extra of STB fertilizer dose. The highest system productivity was also produced by 20 % organic amendments (33.6 t ha-1), followed by 25 % extra of STB fertilizer dose (32.3 t ha-1). The lowest yield of crops and system productivity was recorded in FP (28.6 t ha-1).The increased yield of T. Aman rice and onion in 20 % organic amendment by cowdung and ST resulted in the highest net return (NR) and benefit-cost ratio (BCR), while 25% extra of STB and FP under CT gave the lowest NR and BCR. Residual nutrient from successive use of cowdung combined with chemical fertilizers outperformed other management practices in terms of crop yield and economic return. Bangladesh J. Agril.

Resumen
The present study attempts to identify the suitable crop sequences in an agriculturally productive district of Bihar, India. Rice-rice-vegetables, rice-maize-rice, rice-maize-maize, rice-maize-jute, rice-pulse-rice, rice-pulse-jute, rice-pulse-potato, and maize-maize-rice were found to be the suitable crop sequences in the area under study. Findings revealed that most of the blocks were found suitable for suggested crop sequences, while only two blocks (namely Balrampur and Barsoi) showed low potential in the rice-maize-rice sequence. Use of farm machinery, application of efficient farm inputs, and irrigation is required to maximize the yield and achieve long-term agricultural sustainability in this district.

Resumen
The study was conducted to determine the yield and economic consequences of two cropping patterns viz. improved cropping pattern (Wheat-Jute-T.aman rice) and farmers, pattern (Wheat-Jute-T.aman rice) through incorporation of modern high yielding varieties and improved management practices for crop production. The experiment was laid out in randomized complete block design with five dispersed replications in farmers’ condition in Faridpur during two consecutive years 2011-12 and 2012-13. Two years mean data showed that the improved management practices for the pattern provided significantly higher yield in Wheat, Jute and T.aman rice. The gross return (Tk. 265495/ha) and net return (Tk.123087/ha) of improved pattern were 9 % and 18 % higher, respectively compared to that of farmers’ pattern with only 3% extra cost. The higher benefit cost ratio, land use efficiency, production efficiency and sustainable yield index indicated the superiority of the improved pattern over the farmers’ practices.J.

Resumen
The experiment was conducted at the farmers field of FSRD site, Elenga and MLT site Modhupur, Tangail during two consecutive years 2011-12 and 2012- 13 to study the productivity, production efficiency, land use efficiency and economic return of the improved cropping pattern (Mustard - Boro - Jute -T. Aman) against the existing cropping pattern (Mustard -Boro - T. Aman) through incorporating of modern crop varieties and improved management practices. The experiment was laid out in randomized complete block design with six dispersed replications. The pooled data of improved management practice for the pattern produced significantly higher yield in Mustard and T. Aman rice respectively and also gave additional jute yield. The gross return and gross margin were higher in improved pattern compared to that of existing farmer’s pattern with only 149 and 151% extra cost at FSRD site, Elenga and MLT site Modhupur, respectively. The higher benefit cost ratio (1.74 and 1.79), rice equivalent yield (22.41 and 21.82), production efficiency (40.19 and 39.48) and land-use efficiency (95.75 and 96.48) indicated the superiority of the improved pattern over the farmer’s existing pattern at both sites. Higher rice equivalent yield indicates that improved cropping pattern (Mustard - Boro - Jute -T. Aman) could be suitable in Tangail region for increasing crop productivity as well as cropping intensity.Bangladesh J. Agril. Res. 40(2): 259-270 June 2015

Resumen
In rainy season, many jute-growing zones of India remain waterlogged affecting its yield and quality. An ex- periment was conducted during 1998 and 1999 under controlled conditions to evaluate the impact of waterlog- ging and drainage [O, 5, 10, 15, 20, 25 and 30 cm water heads with a well-drained condition (40 cm) as control] on 'JRO 524'tossa jute (Corchorus olitorius L.). Jute plants lodged within a week, survived for 20 to 30 days at 10 to 30 cm water head, exhibited premature leaf senescence and poor growth (up to 40, 41, 80 and 56% reduction in plant height, basal diameter, tap root dry weight and photosynthetic rate respectively). Waterlogging increased the stomata1 resistance of jute leaves. It reduced nutrient uptake by jute plants and microbial population of soil. Waterlogging reduced the fibre yield from 20 to 60% and its strength from 12 to 55%. Waterlogging resulted in in- ferior quality jute fibre. In medium lands, drainage in C. olitorius jute will augment its fibre yield from 20 to 60% consistent with quality.

Resumen
An experiment was conducted at Barrackpore during 2003-2005 to find out suitable eco-friendly and remunera- tive integrated weed-control approaches for jute cv W O 524i (eNavini). Cultural, organic and integrated chemical weed-control methods were found better than conventional manual weeding twice. In cultural method, smothering of weeds by leafy vegetable mixtures [red amaranth (Amaranthus tricolor L., cv Babakusumi), white amaranth (Amarantus spp.) and summer radish (Raphanus sativus L. cv Paus mulai] in jute, reduced the dry matter of weeds up to 45% when the field was dominated by grasses and broad-leaf weeds. This was followed by two manual weedings which gave 3.57 tlha jute fibre (along with 2.9 tlha red amaranth, 0.6 tlha white amaranth and 0.7 tlha summer radish, respectively). The organic approach, rice straw mulch @ 10 tlha and mixed cropping with same vegetables, followed by one manual weeding produced 3.9 tlha jute fibre (1.15, 0.64 and 0.94 tlha red and white amaranth and summer radish, respectively). It reduced the dry matter of weeds by 68 to 82%. In integrated chemical approach, spray of quizalofop ethyl (DT,, c Id) Q 60 glha + dhanuvit @ 0.5 to 0.6 Ilha (adjuvant) at 21 DAE combined with 1 hand weeding produced 3.87 tlha jute fibre. The benefit : cost ratio from conventional, cul- tural, organic and chemical approaches was l .50, .57, 2.1 9 and l .66 respectively. The residue of quizalofop ethyl l was found below the detectable limit (0.84 to 4.2 ppm) within 8 days of its application.

Resumen
The study was conducted in jute-growing areas of West Bengal (India) to explore the potential resource use efficiency for economic benefits of selected climate smart practices to marginal landholder farmers. Integrated crop management (ICM) practices as part of climate smart jute farming (CSJF) was practised by 170 randomly selected farmers in six villages. An estimation of cost of adoption, change in fibre yields, net returns and human development index (HDI) before and after ICM interventions was done. The mean HDI value increased by 38.85% and farm income by 31.5%. The net benefits of adaptation to climate smart jute technologies were estimated based on specific adaptation actions. Empirical scientific evidence of the study indicates that the livelihoods of marginal landholders can be improved using new crop varieties, changing planting dates and bringing necessary changes in other variable inputs for line sowing, intercropping, weeding, nutrients, water and retting.

Resumen
The study examines carbon and energy footprints of jute, kenaf, sunnhemp and flax fibre production systems. Energy productivity was lowest in flax fibre production as compared to other fibre crops. Flax fibre production consumed more chemical fertilizer, diesels, pesticides and seed energy in comparison to other fibre crops. The carbon footprints of the all fibres crops did not differ significantly and were in the order of 566, 520, 445 and 423 kg CO2-eq/tonne of fibre for jute, flax, kenaf and sunnhemp, respectively. The carbon based sustainability index for jute (2.27) and kenaf (2.07) were highest due to better carbon use efficiency. Sustainability index of flax was negative (-0.67) due to higher carbon emission. Fertilization and fibre processing contributed most to GHG emissions. Overall, the carbon footprint of bast fibres was 20–50% lower than that of synthetic/artificial fibres.

Resumen
Crop insurance is an essential tool for managing risk in agriculture. The primary goal of this study was to investigate how farmers felt about crop insurance and their willingness to pay for it. . The study was conducted to profile the socioeconomic characteristics, measure the profitability of crops, assess farmer’s willingness to pay crop insurance, and determine the factors that influence willingness to pay (WTP). A total of 107 farmers were chosen at random from Kishoreganj district in Bangladesh. The data were collected through a field survey using a semi-structured interview schedule. Karl Pearson’s correlation coefficient method was used. The study found that the majority of farmers have only had primary education or less. About one-third of the respondents could make savings of ten to twenty thousand taka each year. The most profitable crops were vegetables, jute, and wheat. Rice’s profitability, however, was hardly positive. Factors such as age, education, occupation, net income, and cultivable area have a positive correlation with the WTP for crop insurance for all crops except rice. However, the uptake of crop insurance is still relatively low in Bangladesh, and more efforts are needed to increase awareness and promote the benefits of crop insurance among farmers.

Resumen
The jute yellow mite Polyphagotarsonemus latus constitutes one of the major pests of jute crop in Bangladesh. The objective of this work was to find out the sources of resistance/tolerance accessions against jute yellow mite. This experiment was carried out in the fields of Bangladesh Agricultural University, Mymensingh, JAES, Manikganj and the Central station, BJRI, Dhaka, during jute growing seasons 2011 and 2012. Out of 79 accessions, only 13 accessions were found less susceptible to yellow mite. These accessions were studied further in the field and net-house condition. Considering the level of infestation in the net-house condition only three accessions namely 1510, 890 and 33-1-244 (A) 2 were found to perform better showing 9.75, 9.68 and 9.93% infestation. In field condition, in case of olitorius, accession 1510 showed lowest infestations (9.90%) giving maximum plant height 324.15 cm and yield 3.26 ton/ha. In case of capsularis, accession 890 also resulted minimum infestation (10.23%) giving satisfactory plant height 315.27 cm and yield 3.14 ton/ha respectively. Accessions 1510, 890 and 33-1-244 (A) 2 could be recommended as breeding materials for evolving yellow mite resistant jute variety.

Resumen
An experiment was conducted to evaluate the fertilizer dose for jute cultivation at the field after harvesting of onion at Gangabordi and Talma, Faridpur during 2017 with five treatments with different level of Urea, Triple Super Phosphate, Muriate of Potash and Gypsum. The result revealed that the treatment of higher doses of fertilizer gave the statistically significant highest fibre (2.76t/ha) yield whereas treatment of lower doses of fertilizer gave the lowest fibre yield (2.40 t/ha) but the Benefit Cost ratio from different treatment showed statistical non significance. From the view of economic profitability, farmers may use no fertilizer at their field during jute cultivation where previous crop was onion.

Resumen
Plants are naturally growing on the soil without hampering the eco-friendly environment. Intensive cultivation of crops with high yielding verities (HYV) hampering the soil health resulting unfertile soil. In addition, frequent uses of chemicals as well as overdose of synthetic fertilizer creating hazardous environment for the living things. However, to meet up the demand of foods as well as other basic requirements of increasing population of the world crop cultivation techniques need to be modernized. To overcome this situation, application of organic fertilizer need to apply regularly. Biochar can be a good source of organic fertilizer and it is currently using to improve the soil health globally. To examine the effect of biochar on jute growth and yield an experiment was set up in two different locations (Jute Agriculture Experimental Station (JAES), Manikganj, and Jute Research Sub Station (JRSS), Jashore of Bangladesh) during the period from August to December, 2019. Results revealed that location (JAES) had significant and positive effect on jute physiology and seed yield and as well as seed quality. Among fourteen treatments, treatment T2 (Recommended dose of fertilizer (RDF)) showed the highest plant height (163.5 cm), base diameter (7.44 mm) and pod per plant (16.5) compare to the rest treatments. Treatment T6 (RDF 75% + 25%biochar@3.0tonha-1) showed the best seed weight (2.13 g) and seed yield/ plant (3.98 g) among all treatments. Interaction among treatments and locations, T2 x L2 affected seed germination (99%) and field emergence (92.33%) positively. From this research it was cleared that biochar alone may not enough but combination is required for improving jute seed yield and quality.

Resumen
This study examined the utilization of crop residues in agrarian zone of Bangladesh. Two categories of respondent participated in this study, such as old conservational agriculture research or farmer group and new conservational agriculture research or farmer group. Data were analyzed using both descriptive and inferential statistics. Crops grown within the study area includes rice, wheat, jute, pulses, oilseeds, maize, vegetables etc. Result of analysis shows that crops residues were mainly used for feeding their livestock (67.30%), cooking fuel (63.46%) and organic manure (74.04%) on the farms in old conservational agriculture research sites, where in new conservational agriculture research sites was used for feeding their livestock (68.64%), cooking fuel (57.06%) and organic manure (61.86%). It can therefore be concluded that crop residue are used within the study area as cooking fuel, animal feed, use with cow dung boll, fired at field, reuse during next cultivation and organic manure on farms.

Resumen
Jute is a major commercial crop grown by majority of the small and marginal farmers of West Bengal. To make this venture profitable ICAR-Central Research Institute of Jute and Allied Fibres (CRIJAF) had developed innovative jute production technologies. The study was conducted during 2021 at villages of North 24 Parganas and Nadia districts of West Bengal where ICAR-CRIJAF had disseminated its innovative technologies. A sample of 160 jute growers comprising of 80 adopter farmers and 80 non-adopter farmers were selected randomly. The objective was to identify the influence of the socio-psychological characteristics of the jute growers on their level of technology socialisation. Canonical correlation analysis was carried out to find the association between these two sets of variables. The variables; achievement motivation, innovativeness, education, land holdings etc. moved together with adoption whereas farming experience and age followed the same direction as rejection and discontinuance.

Resumen
SUMMARYPaddy rice was grown without fertilizer after jute which had been supplied with nitrogen as neem cake coated urea (NCU), wax coated urea (WCU), ammonium sulphate or standard urea at rates of 0, 40, 80 or 120 kg N ha−1. NCU or WCU applied to jute increased the dry matter and grain yield of the rice, suggesting that enough nitrogen is left behind to grow a subsequent rice crop without further fertilizer application.

Resumen
Jute (Corchorus capsularis) is a widely cultivated fibrous species with important physiological characteristics including biomass, a deep rooting system, and tolerance to metal stress. Furthermore, Corchorus species are indigenous leafy vegetables and show phytoremediation potential for different heavy metals. This species has been used for the phytoremediation of different toxic pollutants such as copper (Cu), cadmium (Cd), zinc (Zn), mercury (Hg) and lead (Pb). The current literature highlights the physiological and morphological characteristics of jute that are useful to achieve successful phytoremediation of different pollutants. The accumulation of these toxic heavy metals in agricultural regions initiates concerns regarding food safety and reductions in plant productivity and crop yield. We discuss some innovative approaches to increase jute phytoremediation using different chelating agents. There is a need to remediate soils contaminated with toxic substances, and phytoremediation is a cheap, effective, and in situ alternative, and jute can be used for this purpose.

Resumen
Jute crop cultivated in Cooch Behar suffers a substantial amount of physical and economical loss every year due to several major insect pest infestation such as Yellow Mite (Polyphagotarsonemus latus Banks) and Jute Semilooper (Anomis sabulifera Guen). Constructed seasonal plots reveal that for Yellow Mite pest incidence is maximum at 55 DAS, while for Jute Semi Looper it is at 45 DAS. Correlation analysis indicate that the weather parameters such as minimum temperature at current week, maximum RH at one week lag, minimum temperature, minimum and maximum RH at two week lag are significantly correlated with the incidence of Yellow Mite, while in case of Jute Semilooper maximum temperature, minimum and maximum RH at two week lag are significantly correlated. Different forecasting models like ARIMA, ARIMAX, SARIMA, SARIMAX and SVR have been fitted and validated using RMSE values. In case of Jute Semilooper, SARIMAX model is found to be the best fitted model followed by SVR and SARIMA. Similarly, for Yellow Mite ARIMAX model produces the least RMSE value followed by SVR and ARIMA. Following successful model validation, forecasting is done for the year 2022 using the best fitted models.
