Background: Soybean-wheat is the most dominant soybean based cropping system and it also fits well in soybean-spring maize and soybean-gobhi sarson cropping systems. Soybean being a highly nutrient-exhaustive crop requires higher amounts of nutrients, particularly phosphorus for its optimum production. Thus, the present investigation was undertaken. Methods: A field experiment was conducted for three years to study the effect of phosphorous application on yield and P uptake by soybean in different cropping systems. There were three cropping systems which were kept in main plots and five P levels viz., 0, 20, 40, 60 and 80 kg P2O5 ha-1 applied to soybean which were kept in the sub plot. Result: Application of 80 kg P2O5 ha-1 resulted in highest mean seed yield of soybean (20.9 qha-1) but significant response was observed up to 40 kg P2O5 ha-1 (19.8 qha-1) only. Highest mean seed P uptake of soybean was observed under application of 80 kg P2O5 ha-1. The mean seed yield, stover yield and P uptake of soybean was not affected significantly under different cropping systems. The interaction effects of cropping system and applied P levels were however non-significant. A significant build-up of available P in surface soil over control was observed under 80 kg P2O5 ha-1 level.

A field experiment was conducted in B deficient soil (0.37 mg kg-1) to assess the frequency and level of B application for increasing crop yields in maize - sunflower cropping system, fate of B pools in soils system and to monitor the changes in soil fertility and productivity due to different levels and frequency of B application under continuous cropping system at Tamil Nadu Agricultural University, Coimbatore since 2012. The analysis of initial soil samples indicated that experimental soil was neutral in soil pH and free from salinity with sandy clay in texture. The grain and stover yield of maize crop varied from 5.51-8.38 and 5.16 to 8.00 t ha-1 , respectively and significantly differed with rate of B application. Among the B levels application of B @ 1.0 kg ha-1 registered the maximum grain and stover yield of 7.55 and 7.00 t ha-1 , respectively and was followed by application of 1.5 kg ha-1, however they were on par with each other. After the harvest of maize crop, sunflower was raised and harvested and the grain and stalk yields were recorded. Among the B levels, application of B @ 1.0 kg ha-1 registered the maximum seed yield of 2.33 t ha-1 respectively and was followed by application of 0.5 kg ha-1. The interaction between the rate of B application and frequency significantly differed with grain and stalk yield. Among the frequency levels, application of B to maize crop alone every year (F3) registered the maximum seed yield as compared to others. The interaction effect revealed that application of B @ 0.5 kg ha-1 to all crop registered the highest seed yield of 2.79 t ha-1 respectively. Boron fractions like available boron, specifically adsorbed B, oxide B, organically bound B, residual B status and total boron contents were analysed after the harvest of second crop. The results revealed that the available B status varied from 0.277 to 1.940 mg kg-1,specifically adsorbed B ranged from 0.190 to 1.332,oxide bound B status in soil varied from 0.127 to 0.89 mg kg-1, organically bound B status in soil varied from 0.235 to 1.644 mg kg-1, residual fraction of B varied from 41.61 to 291.8 and total boron varied from 42.44 to 297.6 mg kg-1. Boron application resulted in significant increase in maize yield as first crop and sunflower as residual crop, respectively. Among the B fractions the order was residual B >organically bound > specifically adsorbed > oxide bound B. Application of B @ 2.0 kg ha-1 significantly registered the highest available B in soil (1.038 mg kg-1) and among the frequencies, application of B to all crops registered the highest available B (1.32 mg kg-1). The actual fraction of B fertilizer removed by the crops is only 1-2 % of the total applied fertilizer through soil.

In a four-year period (1997–2000), selected phytonutrients, of which the beta-glucan content is most important for human health, were studied in caryopses of different types of barley varieties and lines (standard, waxy, hulless) from two cropping systems. It was significantly highest in the waxy variety Washonubet (4.93%). The whole group of waxy types of barley showed a significantly higher mean content of beta-glucans (4.75%) than the varieties with standard starch composition (4.12%), the starch content, however, was significantly higher in standard varieties (61.98%) than in waxy types (60.30%). The hulless varieties, however, had a significantly higher mean starch content (61.73%) than the hulled forms (61.07%) and a significantly higher protein content (13.82% versus 13.00%). The hulless intensive varieties and lines had a significantly higher content of beta-glucans (4.34%) and protein (13.95%) than the hulled intensive varieties (4.07%, 12.65%). Chemical treatment and fertilization increased significantly only the mean content of protein in caryopses (13.77%) compared to the variants with the absence of treatment (13.13%), the content of beta-glucans and starch increased insignificantly (by 0.12% and 0.27%). Years and varieties participated most in the variability of starch content (31.67%, 28.08%), varieties in the content of beta-glucans and protein (per 22%), and (21%) the interaction of varieties and years in the variability of these two nutrients.

The costal saline zone of West Bengal in India is the home for millions of the world’s poorest and most vulnerable people. Due to gradual increase in salt accumulation on soils of the costal saline zone of West Bengal in India from winter to summer days, cultivation of the second crop in winter season becomes possible in a limited area. To address this issue, field experiment was conducted both in rainy and winter seasons of 2016–2017 and 2017–2018 in this zone to study the feasibility of incorporating different winter pulses (lentil and grass pea) in the rice based cropping system. The experiment was conducted in strip plot design having two factors namely, Factor I: Six dates of sowing of rice at an interval of one week (2nd week of June to 3rd week of July) and Factor II: Two land situations (Medium-upland and Medium-lowland). Date of sowing significantly influenced dry matter and macro-nutrients (NPK) partitioning in rice. Irrespective of land situation, crop sown on 1st and 2nd dates recorded significantly higher grain yield and macro-nutrient uptake by rice. Date of sowing of rice and land situation also significantly influenced the seed and stover yield of different pulse crops. Pulse crops sown on 1st and 2nd dates recorded significantly higher seed yield in coastal saline ecology of West Bengal, India.

Soil organic carbon is strongly affected by agricultural management practices. Cropping systems can influence the amount of carbon present in soil. Increase in SOC can be related with the choice of crops present in the cropping sequence as well as on the management practices followed. The present study was undertaken to quantify the changes in soil carbon stock under different cropping systems. Two major cropping systems i.e. pearlmillet-wheat and pearlmillet-mustard were selected in Mewat, Haryana while soybean-wheat cropping systems was identified in Dhar, Madhya Pradesh. Results showed that SOC of surface soil layer decreased from 0.42% to 0.39% in pearlmillet-mustard cropping system during the study period. But in soybean-wheat cropping system it increased from 1.14% to 1.24%. Legume based cropping system showed enhancement of surface soil carbon.

The North China Plain (NCP) is one of the most important grain production regions in China. However, it currently experiences water shortage, severe nonpoint source pollution, and low water and N use efficiencies (WUE and NUE). To explore sustainable agricultural development in this region, a field experiment with different cropping systems was conducted in suburban Beijing. These cropping systems included a winter wheat and summer maize rotation system for one year (WM), three harvests (winter wheat-summer maize-spring maize) in two years (HT), and continuous spring maize monoculture (CS). Novel ways were explored to improve WUE and NUE and to reduce N loss via the alternative cropping system based on the simulation results of a soil-crop system model. Results showed that the annual average yields were ranked as follows: WM > HT > CS. The N leaching of WM was much larger than that of HT and CS. WUE and NUE were ranked as follows: WM < HT < CS. Comprehensive evaluation indices based on agronomic and environmental effects indicated that CS or HT have significant potential for approaches characterized by water-saving, fertilizer-saving, high-WUE, and high-NUE properties. Once spring maize yield reached an ideal level HT and CS became a high-yield, water-saving, and fertilizer-saving cropping systems. Therefore, this method would be beneficial to sustainable agricultural development in the NCP.

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.

In absence of suitable cropping systems in terai, seed yield of mustard is decreasing. Farmers are growing mustard crop under energy starved condition and these are main reasons for low productivity of mustard. With a view to address these issues, an experiment on sustainability of productivity in rice-mustard sequential cropping system through integrated nutrient management for terai condition of Nepal was carried at Nawalpur, Sarlahi during 2004 – 2006. The result revealed that rice grown with 100% recommended dose of fertilizer and 10 tons compost /ha produced a maximum mean grain yield of 4371 kg/ha and straw yield of 5045.5 kg/ha which might be due to maximum dry matter accumulation. Likewise, it was exhibited that application of recommended dose of fertilizer with 10 t compost on preceding rice resulted in maximum seed yield of mustard (1259 kg/ha). The finding also showed that mustard grown with recommended dose of fertilizer produced a maximum mean seed yield of 1384 kg/ha. There was a positive effect of these treatments on seed yield attributes and seed yield of succeeding mustard. Economic analysis for the effects of treatments resulted a maximum benefit cost (BC) ratio of 2.0 which was obtained for mustard when grown after recommended dose of fertilizer. An encouraging BC ratio of 3.45 was found when mustard was taken with 100% recommended dose of fertilize (RDF).

A field experiment was couducted during kharif season of 2010 at the College of Agriculture, Central Agricultural University, Imphal to study the effect of phosphorus on yield and quality of promising varieties of soybean under rainfed condition. Results revealed that application of phosphorus significantly influenced the number of pods per plant, seeds per pod, test weight, seed yield, oil and protein content. The highest seed yield was recorded with the application of phosphorus at 60 kg P2O5/ha and stover yield with 90 kg P2O5/ha. However, the oil and protein contents in seed were significantly increased with the application of phosphorus up to 30 kg P2O5/ha. Residual available nitrogen and phosphorus in soil were increased with increased level of phosphorus up to 90 kg P2O5. Comparable seed yield was recorded in Local and Bragg varieties. Higher protein and oil contents were recorded in Bragg compared to other varieties. The residual available nitrogen was significantly enhanced by cultivation of Bragg over the local variety.

An experiment was conducted at saline agro-ecosystem of Burir Char Union, Barguna District during January to June 2018, with a view to find out  the fertilizer management for maximizing soybean (Glycine max L.) production in saline agro-ecosystem was laid out in randomized complete block design consisted of three varieties of soybean and four levels of fertilizer doses with three replications. Three varieties of soybean viz. BARI Soybean-5, BARI Soybean-6 and Binasoybean-3 and  four fertilizer levels viz. T1 = 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B (Soil test based fertilizer); T2 = 30-40-60-12-2.0-1.0 kgha-1 N-P-K-S-Zn-B (Fertilizer recommendation guide, 2012); T3 = 40-20-15-0-0-0 kgha-1 N-P-K-S-Zn-B (Farmers practices); T4 = Control native fertility were considered  which placed in a factorial randomized block design. The variety had significant influence on plant height, branches plant-1, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, seed yield (t ha-1), stover yield (t ha-1). BARI Soybean-6 performed better than the other two varieties. The fertilizer doses had significant influence on plant height, branches plant-1, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, 100-seed weight, seed yield (t ha-1), stover yield (t ha-1). Fertilizer doses 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B (Soil test based fertilizer) gave the maximum yield. The interaction between variety and fertilizer doses V2T1 (BARI Soybean-6 and 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B) produced the maximum yield SO, the variety BARI Soybean-6  with  fertilizer dose 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B could be suitable combination for higher yield of soybean in saline agro ecosystem of Barguna.
