Abstract:
Crop production must increase substantially to meet the needs of a rapidly growing human population, but this is constrained by the availability of resources such as nutrients, water, and land. There is also an urgent need to reduce negative environmental impacts from crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles, appropriate use of inputs, and soil improvement are the core for integrated approaches to solve this grand challenge. This special issue includes several review and original research articles on these topics for an array of cropping systems, which can advise implementation of best management practices and lead to advances in agronomics for sustainable intensification of crop production.

Abstract:
The goals of sustainable agriculture include decreased reliance on synthetic nutrients and pesticides and improved environmental quality for the long-term benefit of the land, livelihood of growers, and their communities. Cropping systems that maximize these goals use alternative fertility and pest control options to produce crops with minimal soil erosion and nutrient leaching. Cropping system elements that can help achieve these goals include: reduced tillage, cover crops, and organic soil amendments. Cover crops are grown before the cash crop and used to replenish the soil with nitrogen and organic matter. Cover crops often also influence pest populations and can be selected based on site-specific growing conditions. Cover crops can be mulched on the soil surface to prevent erosion and weed emergence or can be tilled directly into the soil to incorporate nitrogen and organic matter. Green waste mulch is an increasingly used soil amendment. Many municipalities are encouraging farmers to use green waste mulch in farming systems as an alternative to green waste disposal in landfills. Reduced tillage was once restricted to large-seeded field crops but recent technical advances have made it a feasible option for vegetables and other horticultural crops. Alternative farming practices; however, are still only used by a small minority of growers. Increases in price for organic produce and changes in laws governing farming operations may increase adoption of alternatives to conventional agriculture.

Abstract:
Towards the sustainable food security for a particular area, the policymakers, researchers, extension and development agents need the detailed information of cropping patterns, cropping intensity and crop diversity. Sylhet, a potential region of enormous potentiality of growing crops across the haor area lying below the northeastern Himalyan foothills experience the highest rainfall in the world to make the basin prone to flashflood. That is why, a study was conducted in the region considering all the upazillas during 2016 using the pretested semi-structured questionnaire and validated by appropriate informants with a view to documenting the existing cropping patterns, cropping intensity and crop diversity in the region. As per the study the region is dominated by the rice based cropping pattern. The non-rice based cropping pattern are either few or the area under those cropping patterns are not enough to satisfy the non-rice food requirement of people of the region. Beside these, the cropping patterns and crop diversity appeared as below the expected level. Therefore, much thrust is needed to initiate research and development activities to diversify the single or double-cropped cropping pattern with the introduction of appropriate crops and crop varieties even other non-crop agricultural commodities.Bangladesh Rice j. 2017, 21(2): 273-288

Abstract:
The study was conducted in Bam in 2019 to develop an index to quantify sustainability of cropping systems in the region. The studied cropping systems included single-cropping systems (palm trees) and multi-cropping systems (citrus, palm trees and alfalfa). The studied indices included economic, social, agricultural indices, as well as, personal features, market access, features of communication, education-extension activities, sustainable agricultural knowledge, attitude towards sustainable agriculture, and obstacles facing sustainable agriculture. The results indicated that the amount of sustainability index was lower than the mean value in 0.56% of the farms and this index was higher than the mean value in 0.44% of the others. Comparison of the mean value of sustainability indices in the studied cropping systems indicated that the mean indices of the type of cropping system, attitude towards sustainable agriculture and extension training activities in multi-cropping systems were more than single crops. The mean indices in social participation and the obstacles facing sustainable agriculture in single cropping systems was more than the multi-cropping ones. Some indices including social participation, sustainable agricultural knowledge and education-extension activities in multivariate regression model remained in the final model as variables that had the largest contribution in the rate of change in the dependent variable (sustainability) and explained = 60% of the changes in the dependent variable. The study showed that the sustainability of multi-cropping systems was more than the single-cropping ones.

Abstract:
The long-term sustainability of crop production depends on the complex network of interactions and trade-offs between biotic, abiotic and economic components of agroecosystems. An integrated arable management system was designed to maintain yields, whilst enhancing biodiversity and minimising environmental impact. Management interventions included conservation tillage and organic matter incorporation for soil biophysical health, reduced crop protection inputs and integrated pest management strategies for enhanced biodiversity and ecosystem functions, and intercropping, cover cropping and under-sowing to achieve more sustainable nutrient management. This system was compared directly with standard commercial practice in a split-field experimental design over a six-year crop rotation. The effect of the cropping treatment was assessed according to the responses of a suite of indicators, which were used to parameterise a qualitative multi-attribute model. Scenarios were run to test whether the integrated cropping system achieved greater levels of overall sustainability relative to standard commercial practice. Overall sustainability was rated high for both integrated and conventional management of bean, barley and wheat crops. Winter oilseed crops scored medium for both cropping systems and potatoes scored very low under standard management but achieved a medium level of sustainability with integrated management. In general, high scores for environmental sustainability in integrated cropping systems were offset by low scores for economic sustainability relative to standard commercial practice. This case study demonstrates the value of a ‘whole cropping systems’ approach using qualitative multi-attribute modelling for the assessment of existing cropping systems and for predicting the likely impact of new management interventions on arable sustainability.

Abstract:
Deep drainage or drainage below the bottom of the profile usually occurs when rain infiltrates moist soil with insufficient capacity to store the additional water. This drainage is believed to be contributing to watertable rise and salinity in some parts of the Liverpool Plains catchment in northern New South Wales. The effect of land use on deep drainage was investigated by comparing the traditional long fallow system with more intense ‘opportunity cropping’. Long fallowing (2 crops in 3 years) is used to store rainfall in the soil profile but risks substantial deep drainage. Opportunity cropping seeks to lessen this risk by sowing whenever there is sufficient soil moisture. Elements of the water balance and productivity were measured under various farming systems in a field experiment for 4 years in the southern part of the catchment. The experimental results were used to verify APSIM (Agricultural Production Systems Simulator) by comparing them with predictions of production, water storage, and runoff. The verification procedure also involved local farmers and agronomists who assessed the credibility of the predictions and suggested modifications. APSIM provided a realistic simulation of common farming systems in the region and could capture the main hydrological and biological processes. APSIM was then used for long-term (41 years) simulations to predict deep drainage under different systems and extrapolate experimental results. The results showed large differences between agricultural systems mostly because differences in evapotranspiration contributed to differences in profile moisture when it rained. The model predicted that traditional long fallow farming systems (2 crops in 3 years) are quite ‘leaky’, with average annual deep drainage of 34 mm. However, by planting crops in response to the depth of moist soil (opportunity or response cropping), APSIM predicted a much smaller annual drainage rate of 6 mm. Opportunity cropping resulted in overall greater water use and increased production compared with long fallowing. Furthermore, modelling indicated that average annual deep drainage under continuous sorghum (3 mm) is much less than under either long fallow cropping or continuous wheat (39 mm), demonstrating the importance of including summer cropping, as well as increasing cropping frequency, to reducing deep drainage.

Abstract:
The study was conducted over all 42 upazilas of Chittagong region during 2016 using pre-tested semistructured questionnaire with a view to document the existing cropping patterns, cropping intensity and crop diversity in the region. The most dominant cropping pattern Boro−Fallow−T. Aman occupied about 23% of net cropped area (NCA) of the region with its distribution over 38 upazilas out 42. The second largest area, 19% of NCA, was covered by single T. Aman, which was spread out over 32 upazilas. A total of 93 cropping patterns were identified in the whole region under the present investigation. The highest number of cropping patterns was 28 in Naokhali sadar and the lowest was 4 in Begumganj of the same district. The lowest crop diversity index (CDI) was observed 0.135 in Chatkhil followed by 0.269 in Begumganj. The highest value of CDI was observed in Banshkhali, Chittagong and Noakhali sadar (around 0.95). The range of cropping intensity values was recorded 103−283%. The maximum value was for Kamalnagar upazila of Lakshmipur district and minimum for Chatkhil upazila of Noakhali district. As a whole the CDI of Chittagong region was 0.952 and the average cropping intensity at the regional level was 191%.Bangladesh Rice j. 2017, 21(2): 109-122

Abstract:
Cropping systems of safflower (Carthamus tinctorius L.) with faba bean (Vicia faba L.) under different fertility were compared with sole cropping of each crop during 2015 and 2016 at the Research Farm of Tabriz University in Iran. The treatments were cropping systems (safflower and faba bean sole croppings, intercropping systems of safflower and faba bean with ratios of 1:1 and 2:1), and nutrient levels (100% chemical fertilizers, 60%, 30% chemical + biofertilizers and no fertilizer). A factorial set of treatments based on a randomized complete block design replicated three times was used. Cropping system and fertility effects were significant for yield and yield components of each crop. Yield and yield components were increased with the integrated use of 60% chemical plus biofertilizers for both years, while seed yield was reduced by intercropping. Maximum land equivalent ratio (LER), relative value total (RVT), system productivity index (SPI) and monetary advantage index (MAI) were achieved in nutritive level of 60% chemical plus biofertilizers as intercropped plants in ratio of 1:1 for both years. The total actual yield loss (AYL) values were positive and greater than zero in all mixtures, indicating an advantage from intercropping over sole crops. Intercropped safflower had a higher relative crowding coefficient (RCC) than intercropped faba bean, indicating that safflower was more competitive than faba bean in intercropping systems. From this study, it is inferred that intercropping (safflower and faba bean) with integrated use of the reduced chemical and biofertilizers may give better overall yield and income than sole cropping of each crop species.

Abstract:
The development of agricultural planning largely depends on the reliable and comprehensive statistics of the existing cropping patterns, cropping intensity and crop diversity of a particular area, which will provide a guideline to the policy makers, researchers, extensionists and development workers. A study was undertaken over all the upazilas of Dinajpur region during 2016 using pre-tested semi-structured questionnaire with a view to document of the existing cropping patterns, intensity and diversity for the region. The most important cropping pattern Boro-Fallow-T. Aman occupied about 41% of net cropped area (NCA) of the region with its distribution over all the upazilas. The second largest area, 9% of NCA, was covered by Wheat-Fallow-T. Aman, which was spread over 18 upazilas. A total of 112 cropping patterns were identified in the whole region. The highest number of cropping patterns was identified 30 in Boda upazila of Panchagarh district while the lowest was 11 in Kaharol upazila of Dinajpur district. The lowest crop diversity index (CDI) was reported 0.708 in Birampur followed by 0.753 in Ghoraghat of Dinajpur. The highest CDI was reported 0.955 in Ranisonkail followed by 0.952 in Baliadangi of Thakurgaon. The range of cropping intensity was recorded 206-249% whereas the maximum value was found for Khansama of Dinajpur and minimum for Boda of Panchagarh district. As a whole, CDI and cropping intensity for Dinajpur region were calculated 0.924 and 229% respectively, which indicates that the land use and crop diversification is not quite enough for the national demand.Bangladesh Rice j. 2017, 21(2): 143-156

Abstract:
Cropping pattern exerts significant impact on the population density of the arbuscular mycorrhizal fungi (AMF) and on soil properties. The study examined the population of indigenous AMF communities as well as status of soil properties under different cropping systems in Aluu, Rivers state, Nigeria. Two farm sites of mono cropping and mixed cropping systems and a fallow land (which served as control) were sampled at 0 – 20 cm depth of soil. Soil samples were analyzed in the laboratory for their physical and chemical properties as well as for the estimation of AMF spore density and resulting data were analyzed statistically. Result shows that, soils of the mono cropping and mixed cropping systems are moderately acidic with mean pH values of 5.80 and 5.74, respectively, while the fallow land exhibits a strongly acid soil reaction (pH = 5.29). Concentrations of organic C (9.25 g kg-1), total N (0.97 g kg-1), exchangeable Ca2+ (3.63 cmol kg-1), available P (13.31 mg kg-1) and C:N ratio (7.87) as recorded in the mixed cropping system, were generally higher than the corresponding results in the fallow and mono cropping systems. Spore population of the AMF varied significantly (P < 0.05) across the cropping systems and was highest in the mixed cropping (157 spores 100 g-1 soil) followed by the fallow (144 spores 100 g-1 soil) while the mono cropping (123 spores 100 g-1 soil) had the lowest spore density. Significant negative (P < 0.05) correlations occurred between AMF spore population and soil pH in both the fallow (r = 0.689*) and mixed cropping (-0.670*) systems whereas correlation with C:N ratio was positively significant (P < 0.01) across the cropping systems. Adoption of mixed cropping rather than mono cropping practices should be encouraged in the studied area in order to enjoy maximum benefits of mycorrhizal symbiosis.

Abstract:
The occurrence of diseases on barley and winter wheat was surveyed in a field experiment comparing four conventional and four organic cropping systems in 1982—88. On barley, foliar diseases were of minor importance regardless of the cropping system. On winter wheat, powdery mildew (Erysiphe graminis), yellow rust (Puccinia striiformis) and leaf blotch (Septoria nodorum) were more prevalent in conventional than in organic cropping systems. Root and foot rot diseases (Bipolaris sorokiniana, Fusarium spp. and Gaeumannomyces graminis) were frequent on barley and winter wheat in each cropping system. B. sorokiniana infected stem bases and roots of barley more frequently in organic than in conventional cropping systems. During the first years of the study, a serious epidemic of G. graminis was recorded in certain organic cropping systems

Abstract:
HighlightsOrganic cropping systems were less efficient in energy use.Sugarcane for seed was the highest energy input due to the consumption of 12 t ha-1 of seed.The second largest part of the energy input was the fuel consumed during mechanized operations.Abstract.Analysis of energy use efficiency provides an assessment of non-renewable energy consumption; it is a useful indicator of environmental and long-term sustainability when comparing cropping systems. This study aimed to estimate the energy use efficiency of organic and conventional cropping systems of sugarcane for sugar production in central Cuba. Estimation of the energy use efficiency included analysis of four cropping systems. The energy input in the field until harvest and transport to the sugar mill was the limit of this analysis. The results showed that organic cropping systems were less efficient in energy use because of the greater number of field operations, mainly for weed control by manual and mechanical cultivation. Organic cropping systems also had lower yield compared with conventional systems due to their use of low doses of organic products, instead of agrochemical fertilizers, for plant nutrition. In all cropping systems evaluated, sugarcane used for seed was the largest part of the energy input due to the consumption of 12 t ha-1 of seed, representing an average of 89% of the total energy input for the sugarcane cropping systems. The second largest part of the energy input was the fuel consumed during mechanized operations. Irrigation was the third largest part of the energy input for organic cropping systems and the second largest part of the energy input for conventional cropping systems. Keywords: Agricultural systems, Energy balance, Energy input, Energy output.

Abstract:
Pasture cropping is a farmer-initiated concept of sowing a winter active cereal into a summer-active native perennial pasture. Proponents claim that by using pasture cropping they are able to maintain or improve the perennial pasture. Research was carried out on a Bothriochloa macra dominant pasture at Wellington, in the central western slopes of New South Wales, to compare pasture cropping to conventional no-till cropping and pasture only systems under different fertiliser rates and rotations. Key variables for the comparison included forage and crop production, pasture perenniality and ground cover, soil fertility and water use, and profitability. Our results show that pasture cropping can successfully retain perennial grasses and ground cover while still producing profitable cropping and grazing compared with continuous pasture. Crop yields from pasture cropping were less than 65% of those for conventional no-till cropping, which led to conventional no-till cropping having the greatest, but also most volatile, gross margin throughout the experiment. However, the lower input costs associated with pasture cropping reduced the effects of crop failure on farm profit. While soil moisture differences did not occur between treatments during the experiment, soil fertility, especially N, played a major role in determining crop yield. The role of pasture cropping in farming systems is discussed.

Abstract:
In a multi-enterprise agriculture model, six different cropping systems have been evaluated at research farm of CSSRI Karnal for nutrient availability in surface soil. All the cropping systems left tremendous effect on soil quality. Among the different cropping systems, sorghum-berseem maintained lowest soil pH (8.14) followed by cowpea-cauliflower-potato cropping system (8.35). Sorghum-berseem cropping system was significantly build-up of soil fertility in terms of available nitrogen, (221.1kg/ha) and soil organic carbon (0.59%) as compared to other cropping systems. However, phosphorus (59.80 kg/ha) availability was higher in vegetable system followed by wheat-green gram cropping systems (48.85 kg/ha) than the other cropping systems. Vegetable system of multi-enterprise agriculture model showed more availability of Ca (3.20 me/L), Mg (2.63 me/L) and S (11.71 me/L) than other cropping systems. Higher amount of Fe (8.44 mg/kg) was observed in maize-wheat-green gram cropping system, whereas higher Mn (6.37 mg/kg) was noticed in sorghum-berseem fodder system than the other cropping system. Zn and Cu availability was relatively higher in vegetable system. Under prevailing climatic conditions of Karnal, sorghum-berseem fodder system was found to be the best with respect to soil quality and ready adaptability by the farmers as it was not much changed by climatic variability over the last 6 years. Vegetable system and fruits + vegetable were more or less similar in accelerating the availability of nutrients. Thus, leguminous crop (green gram) in any cropping system helped in improving the soil health, which is a good indicator of soil productivity.

Abstract:
Thorough understanding and a reliable database on existing cropping patterns, cropping intensity and crop diversity of a particular area are needed for guiding policy makers, researchers, extensionists and development workers for the planning of future research and development. During 2016 a study was accomplished over all 34 upazilas of Jessore region using pre-tested semi-structured questionnaire with a view to document the existing cropping patterns, cropping intensity and crop diversity in the region. The most dominant cropping pattern Boro−Fallow−T. Aman occupied 32.28% of net cropped area (NCA) of the region with its distribution in all upazilas. The second largest area, 5.29% of NCA, was covered by single Boro, which was spread over 24 upazilas. A total of 176 cropping patterns were identified in the whole region under the current investigation. The highest number of cropping patterns was identified 58 in Kushtia sadar upazila and the lowest was 11 in Damurhuda upazila of Chuadanga district. The lowest crop diversity index (CDI) was reported 0.852 in Narail sadar upazila followed by 0.863 in Jessore sadar upazila. The highest value of CDI was observed 0.981 in Daulatpur followed by 0.978 in Bheramara upazila of Kushtia district. The range of cropping intensity values was recorded 175−286%. The maximum value was for Sreepur of Magura district and minimum for Abhaynagar of Jessore district. As a whole the CDI of Jessore region was calculated 0.955 and the average cropping intensity at regional level was 229%.Bangladesh Rice j. 2017, 21(2): 185-202

Abstract:
Among several alternative agricultural systems have been developed, organic agriculture has deserved increasing interest from. The objective of this paper was comparing both organic (OS) and conventional (CS) tomato cropping systems for varieties Débora and Santa Clara, through an interdisciplinary study. The experiment was set up in a randomized blocks design with six replicates, in a dystrophic Ultisol plots measuring 25 ´ 17 m. Cropping procedures followed by either local conventional or organic growers practices recommendations. Fertilization in the OS was done with organic compost, single superphosphate, dolomitic limes (5L, 60 g, and 60 g per pit), and sprayed twice a week with biofertilizer. Fertilization in the CS was done with 200 g 4-14-8 (NPK) per pit and, after planting, 30 g N, 33 g K and 10.5 g P per pit; from 52 days after planting forth, plants were sprayed once a week with foliar fertilizer. In the CS, a blend of insecticides, fungicides and miticides was sprayed twice a week, after planting. In the OS, extracts of black pepper, garlic, and Eucalyptus; Bordeaux mixture, and biofertilizer, were applied twice a week to control diseases and pests. Tomato spotted wilt was the most important disease in the OS, resulting in smaller plant development, number of flower clusters and yield. In the CS, the disease was kept under control, and the population of thrips, the virus vector, occurred at lower levels than in the OS. Variety Santa Clara presented greater incidence of the viral disease, and for this reason had a poorer performance than 'Débora', especially in the OS. Occurrence of Liriomyza spp. was significantly smaller in the OS, possibly because of the greater frequency of Chrysoperla. The CS had smaller incidence of leaf spots caused by Septoria lycopersici and Xanthomonas vesicatoria. However, early blight and fruit rot caused by Alternaria solani occurred in larger numbers. No differences were observed with regard to the communities of fungi and bacteria in the phylloplane, and to the occurrence of weeds.

Abstract:
Abstract Of the 5000 grass species identified worldwide, more than 1400 may be found in the United States (17). The potential benefits of interplantings in horticultural crops justifies the effort to identify the most appropriate grasses for this practice. Grass interplantings are used to reduce erosion, increase water infiltration into the soil, improve traffic-carrying ability, improve soil structure, limit weed invasion, moderate soil temperatures, and reduce soil contamination of crops. Disadvantages in using grasses for interplantings include increased competition for water and nutrients, harborage of pests, and expense of establishment and maintenance.
