Resumen

Abstract This article considers the solution for the automation problem in rice growing. Currently, every seventh resident of the earth is involved in rice growing and processing, and all countries experience insufficiency of labor resources for this work. To solve this problem, the authors suggest using an automated agricultural self-propelled platform (AASPP) that will help completely automate rice growing and solve environmental, economic, social, and infrastructural problems of rural residents. Besides, it can help eliminate many of the technical problems of rice growing, such as the horizontal leveling off the field, corrosion of agricultural machines, complying with agrotechnical standards when planting, and the correlations between the terms of agrotechnological works using machines and mechanisms and soil humidity and other natural conditions. Solving the problem of rice growing automation will help satisfy the needs of this agricultural sector in labor and free 30-50% of people involved in rice growing to be employed in other economic sectors.

Resumen

Mechanical transplanted seedling must meet the requirements of standard seedling block with uniform distribution of seedlings and inter-twisting roots for rolling. This study was conducted to identify the effect of growing media on mat type seedling raised for mechanical transplanting at Bangladesh Rice Research Institute (BRRI), Gazipur during the period of 2012–2014 covering two dry and cold seasons (Boro) and one wet season (Aman). Seedling were raised on plastic tray using sandy loam and clay loam soil mixed with decomposed cow-dung, mustard cake, rice straw organic fertilizer, rice bran, poultry litter and vermicompost at the rate of 0.0, 10, 20, 30 and 40%. Rolling quality of the seedling mat decreased and seedling height increased with the increased of mixing rate of organic fertilizer except rice bran and mustard cake. Averaged across three seasons, 10 to 30% cow-dung, rice straw organic fertilizer, vermicompost, 10% poultry litter and 20 to 30% rice bran with both types of soil was found suitable for seedling mat and seedling height. However, seedling varied among the organic fertilizers with both types of soil in the order of cow-dung > rice bran > vermicompost > poultry liter > rice straw organic fertilizer > mustard cake. Clay loam soil showed better performance on rolling quality over sandy loam soil.

Resumen

The experiment developed the ultra-high-performance liquid chromatography–tandem mass spectrometry (UPLC/MS/MS) method for testing emamectin benzoate, and studied the metabolism of emamectin benzoate in rice plants and rice-growing environments via application of this testing method. The dissipation curve of emamectin benzoate standard substance was good at 0.5–200 μg L−1, and its correlation coefficient was greater than 0.99. In the concentration range of 0.1–50 μg kg−1, the average recovery rate of plants, soil, and field water was 82 %–102 %, and relative standard deviation (RSD) was between 0.3 % and 15.9 %. Half-lives in rice plants and soil were 0.8–2.8 days and 1.9–3.8 days, respectively, and emamectin benzoate was not detected in rice or rice hull. The experiment showed that emamectin benzoate is harmless to human health at the concentration recommended by the manufacturer.

Resumen

Irrigated rice production can involve environmental contamination with pesticides due to the proximity of the fields to rivers and to management problems. During three years (2000 to 2003) the rice herbicides clomazone, propanil and quinclorac were quantified in water during the rice growing season, in the Vacacaí and Vacacaí-Mirim Rivers, located in Rio Grande do Sul (RS) State, Brazil. Water samples were taken at several locations in each river, selected by their importance in terms of rice drainage area. The samples were analyzed by HPLC-UV. At least one herbicide was detected in 41% of the samples from the Vacacaí River and 33% from the Vacacaí-Mirim River. The most frequent herbicide in both rivers and in each year was clomazone. The amount of herbicides in the river water was dependent on the rainfall regime. River water contamination by rice herbicides is probably caused by the rice water management used in the fields. The maintenance of flooded areas makes herbicides prone to contaminate the environment. To reduce the environmental contamination risk it is necessary to adopt measures to avoid overflow of flooded rice fields, keeping paddy water in the field for time enough to reduce the herbicide concentration before its release and enhancing the quality of the levees to reduce the probability of paddy rice overflow.

Resumen

The Krasnodar region is the main rice-producing region in the Russian Federation. The gross yield of rice in the Kuban area is more than 80% of the national total. The rice irrigation systems occupy 234.5 thousand hectares, about 130 thousand of which are sown with rice in accordance with a scientifically based crop rotation. Over the past 5 years, the volume of rice production increased by 114.8 thousand tons and amounted to 823.6 thousand tons in 2019, and the average yield increased by 6.2 centners/ha. The economic indicators of crop production have also increased: in 2019, the total costs per hectare amounted to 89289.0 rubles, which is 24876.7 rubles higher in comparison with 2015. Over 5 years, the growth in all cost items and especially in material costs amounted to 11087 rubles. The cost of one ton of rice for the period of 2015-2019 has increased by 3389.9 rubles.

Resumen

The world practice of rice cultivation has shown that rice cultivation by traditional methods for Russia is labor-intensive, resource-intensive, ineffective with low profitability, and often unprofitable production. As a result, traditional methods of flooding rice paddies in Russia are faced with a shortage and high cost of irrigation water and a reduction in rice irrigation systems, i.e., areas suitable for rice cultivation. For solving the problem of unprofitable rice production, an analysis of the world practice of rice production has been implemented. The analysis showed that the most optimal solution for the natural and climatic conditions of the Krasnodar Territory is the cultivation of rice using sprinkler irrigation and drip irrigation. Further analysis showed that drip irrigation is the most promising way of growing rice, which has many undeniable advantages. The main advantages of drip irrigation are the low irrigation rate, labor intensity, and energy intensity of rice production. Therefore, the article proposes a pioneering Russian ridge cultivation method for rice cultivation on the lands of the irrigated rice fund with drip irrigation under plastic and/or biodegradable perforated film. This method will make it possible to radically revise the principles of rice cultivation, form a new generation of rice crop rotations with the inclusion of melons and vegetables in them, and carry out rice production on previously rainfed lands. The implementation of the method has proven the effectiveness and feasibility of our research.

Resumen

Blast (causative agent Pyriculariaoryzae Cavara) plays an important role among economically important, dangerous and harmful rice diseases of rice in all rice-growing countries, including Russia. The problem of resistance of rice plants to disease is one of the main problems in modern breeding in most countries. Intensification of rice cultivation creates a favorable microclimate in the sowing agrocenosis for the development of blast disease and leads to an increase in its harmfulness. The varieties quickly lose their resistance to new races of the pathogen, due to high spontaneous variability of the M. grisea fungus, its field populations are usually represented by a mixture of races with different virulence and aggressiveness, outstripping the evolution of the host plant. The nature of the blast manifestation depends on the agroclimatic conditions and genotype. The article presents the results of research at experimental and production plots of Federal Scientific Rice Centre (FSC of Rice) and Elite Seed-Production Experimental Statation Krasnaya (ESPES Krasnaya). It has been shown that a clear differentiation of rice varieties in terms of blast resistance and yielding properties is possible only when certain (provocative) conditions are created that contribute to the manifestation of their genetic potential, while the blast resistance of varieties cannot be provided only by the introduction of one gene of racespecific resistance. A close negative relationship was obtained between the yield and the intensity of blast disease on two backgrounds of mineral nutrition: N-1 - r = -0.93; N-2 - r = -0.95. The determination coefficients showed that in 86.8 - 90.1% of cases, the yield is due to the intensity ofblast development on the crops of the studied rice varieties.

Resumen

The spatial and temporal distributions of heat unit and various agrometeorological indices for the rice crop, are studied in this paper. Eight ET – stations were selected from six rice growing zones, viz., Canning (in lower Gangetic plains), Bikramganj and Varanasi (in middle Gangetic plains), Ludhiana (in trans Gangetic plains), Ranchi, Shymakhunta (in eastern plateau and hills), Annamalai Nagar (in east coast plains and hill region) and Pattambi (in western plains and ghat region). Eleven crop growth stages were identified for this study, viz., germination, nursery seedling, transplanting, tillering, active tillering, lag phase, panicle initiation, flowering, grain formation, grain maturity and harvesting, the duration of each of the growth stages varied widely, station wise. Daily data were collected growth stagewise for latest available five years and the mean values were computed for the derived parameters, viz., the crop requirements of heat unit, agroclimatic rainfall index (ARI), yield moisture index (YMI), aridity index (AI). The study revealed that for rice crop the total degree days requirement varied from 1706 degree – days (at Ranchi) to 2815 degree – days (at Shymakhunta). It showed primary peak (with 16.7 % of total requirement) at active tillering stage. The ARI values were mostly higher than 100 per cent. The mean YMI values varied widely from 477 mm (at Bikramganj) to 1523 mm (at Pattambi). The values showed main peak at active tillering stage. The AI values showed moderate aridity at early growth stages, which increased at advanced crop growth stages.

Resumen

The inconsistency of the Indian monsoon has constantly threatened the country’s food production, especially key food crops such as rice. Crop planning measures based on rainfall patterns during the rice-growing season can significantly improve the sustainable water usage for water-intensive crops such as rice. This study examines the variability of Indian monsoonal rainfall in rainfed and irrigated rice-cultivating regions to improve rainfall utilization and irrigation water-saving practices. Two distinct rice-growing conditions in southern peninsular India are chosen for this study. The preliminary seasonal rainfall analysis (1951–2015) showed anomalies in the Sadivayal (rainfed rice) region compared to the Karaikal (irrigated rice). The dry-spell analysis and weekly rainfall classification suggested shifting the sowing date to earlier weeks for the Thaladi season (September–February) and Kar season (May–September) to avoid exposure to water stress in Sadivayal. Harvesting of excess rainwater during the wet weeks is proposed as a mitigation strategy for Karaikal during the vegetative stage of the Kuruvai season (June–October) and Late Thaladi season (October–February), where deficit rainfall is expected. Results showed that an adaptation strategy of early sowing is the most sustainable measure for rainfed rice cultivation. However, harvesting the excess rainwater is an ideal strategy to prevent water stress during deficient rainfall periods in irrigated rice farming. This comparative study proposes a comprehensive rainfall analysis framework to develop sustainable water-efficient rice cultivation practices for the changing rainfall patterns.

Resumen

An experiment was conducted to study the effects of different growing mediums on rice seedlings. Nine kinds of growing mediums were used: AN, AR, BN, BR, CN, CR, DN, DR, mixtures of decomposed chicken feces, soybean cake, plant ash and two organic acid (N and R) with different proportions; CK, a commercial growing medium (XinZu), used as control. Chlorophyll content, soluble sugar, peroxidase activity and root vigor of rice seedlings were analyzed. Results showed that rice seedlings in BR were stronger, with higher contents of chlorophyll, soluble sugar and peroxidase activity. The root vigor of rice seedlings was enhanced in BR. It was indicated that BR could be used successfully as growing medium for organic rice seedling.

Resumen

Most traditional methods for rice mapping with remote sensing data are effective when they are applied to the initial growing stage of rice, as the practice of flooding during this period makes the spectral characteristics of rice fields more distinguishable. In this study, we propose a sequential classifier training approach for rice mapping that can be used over the whole growing period of rice for monitoring various growth stages. Rice fields are firstly identified during the initial flooding period. The identified rice fields are used as training data to train a classifier that separates rice and non-rice pixels. The classifier is then used as a priori knowledge to assist the training of classifiers for later rice growing stages. This approach can be applied progressively to sequential image data, with only a small amount of training samples being required from each image. In order to demonstrate the effectiveness of the proposed approach, experiments were conducted at one of the major rice-growing areas in Australia. The proposed approach was applied to a set of multitemporal remote sensing images acquired by the Sentinel-2A satellite. Experimental results show that, compared with traditional spectral-indexbased algorithms, the proposed method is able to achieve more stable and consistent rice mapping accuracies and it reaches higher than 80% during the whole rice growing period.

Resumen

An experiment was conducted to estimate the crop water requirement of rice and to compare it with the amount of rainfall. Experiment was designed to estimate evaporation and evapotranspiration in cylindrical half cut mineral water bottles. Rice was planted in the bottles to estimate evapotranspiration. The amount of rainfall during the experiment period was recorded in the rain gauge station. The evaporation was highest in the month of September (3.16mm/day) and lowest in June (2.56mm/day). The rate of evapotranspiration was in increasing order from June to September ranging from 3.43 mm/day in June to 19.57mm/day for September respectively. The crop water required was in increasing order reflecting more water required with the increase in days after plantation and successive developmental stage of rice. The total amount of rainfall in the study area over study period (23rd June, to 30th September, 2005) was 549.59mm. The total crop water requirement of rice for same period in the same area was 711.45mm. It showed that the rainfall during the study period was insufficient to meet the water demand for rice in the study area.

Resumen

Rice is a historically important crop in Portugal. This crop development and production strongly depend on atmospheric conditions in the growing season. Given the strong dependence of climatic conditions, climate change may pose a significant risk for future rice production. In the present study, a high spatial resolution bioclimatic characterization over the main rice producing region in Portugal was performed for the recent past (1950–2000) and for the future (2041–2060) under four different anthropogenic forcing scenarios (RCP2.6, RCP4.5, RCP6.0, and RCP8.5). This zoning is performed by using eight bioclimatic indices, based on temperature and precipitation, using a very high resolution gridded dataset (Worldclim). For the future period, an 11-member global climate model ensemble was used, also taking into account model/scenario uncertainties and bias. Additionally, a new index was developed to incorporate the main features of temperature and precipitation at each rice field level. Under recent past climates, a clear north–south gradient in temperature and precipitation is apparent, with the regions of Tejo and Sado presenting higher temperatures and lower precipitation than the Mondego and Vouga regions. Additionally, there is a coastal–inland effect due to the Atlantic Ocean influence. Under anthropogenic climate change, all indices point to annual higher temperatures and lower precipitations across all rice producing regions, accompanied by increased seasonality. Furthermore, the rise of summertime temperatures may substantially increase water demands, which, when unmitigated, may bring physiological problems in the crop development. We conclude that climate change may negatively impact the viability of rice production in Portugal, particularly taking into account the national grown varieties. Thus, adequate and timely planning of suitable adaptation measures are needed to ensure the sustainability of this historically important food sector.

Resumen

Soils of varying K status were selected at the BAU farm, Mymensingh and BADC farm, Madhupur for conducting laboratory, pot, and field experiments to see the dynamics of potassium in wet land rice soils. The soils were BAU-1(0.087 cmol/kg soil), BAU-2 (0.146 cmol/kg soil), Maddhupur-1 soil (0.097cmol/kg soil), and Madhupur-2 soil (0.706 cmol/kg soil). Almost neutral silt loam soils (Sonatola series) of BAU firm developed on the recent alluvial deposits of Old Brahmaputra Flood Plain and the acidic clayey soils (Noadda and Kalma series) of BADC farm developed on Madhupur clay. The laboratory experiments were potassium release capacity of soils, Q/I relationships of potassium. Results of the experiments showed that BADC farm soils released more K than BAU farm soils. The Q/I relationship showed that the equilibrium exchangeable K (EK0) and labile K (KL) of Madhupur-2 soil were higher than other soils. The potential buffering capacity (PBCK) was higher in BAU-2(5.19±0.12 cmol/kg (mol/L)1/2 soil followed by BAU-1 (4.07±0.09 cmol/kg (mol/L)1/2) and then Madhupur-2 soil (2.23±0.04 cmol/kg (mol/L)1/2). BAU farm soils adsorbed 55 to 60% of added K in non-exchangeable form, while it was 33 to 39% in BADC farm soils. DOI: http://dx.doi.org/10.3329/bjar.v36i4.11750 Bangladesh J. Agril.

Resumen

There have been issues of increased broken rice when farmers finally sell their rice crop, especially in the higher altitudes, and this has always been attributed to the quality of milling machines used. In this study, the head rice recovery of two rice varieties grown in high and low altitudes in Bhutan was assessed in both pre-and post-milling through manually peeling and milling in four different types of rice milling machines, respectively. The head rice recoveries on manual peeling of high and low altitude rice varieties were 54.00±0.41% and 83.68± 0.45%, respectively, and were significantly different at P<0.05. Grain crack percentages were 29.44±0.45% and 5.37±0.45%, respectively, indicating that the climatic conditions had some influence on crack development and head recovery of rice. For machine milling, the rice head recoveries were statistically significant both between varieties and among the milling machines used. The head yield was higher in low attitude variety compared to that of the high altitude one. The friction type machine with 3.32 m/s peripheral velocity gave lower head yield compared to friction type of 1.2 m/s and rubber roller type I and II milling machines. This study recommends improving the drying method presently practised in high altitudes by not laying the paddy on the ground after harvest to avoid exposure of harvested paddy to extreme day and night temperature fluctuation. The use of lower peripheral speed rice milling machines and rubber rollers is recommended to increase head yield.
