A field experiment was conducted during the year 2011-13 to study the nutrient management based on soil test to achieve the target yield of jute and rice and their effect of soil nutrient status for jute-rice cropping system. The target yield of jute fibre (3.5 t/ha) with -6% deviation and target yield of rice (5.5 t/ha) were achieved with application of 100% NPK based on ST-TY based along with 5 t/ha Farm Yard Manure (FYM). The highest system productivity (11.7 t/ha) and benefit-cost ratio (3.16) was also recorded higher with application 100% NPK based on ST-TY based along with 5 t/ha FYM. The nutrient uptake by crops and soil nutrients status were higher after three year of jute-rice cropping sequence when NPK were applied with FYM. Hence, combination of inorganic and organic (FYM) fertilizer could achieve target yield and maintain the soil fertility status.

Performance of two fodder crops namely, sorghum (Sorghum vulgare L.) and maize (Zea mays L.) was investigated with Willow (Salix alba L.) to evaluate productivity and economics of the silvopastoral agroforestry system in Kashmir valley. The experiment was laid out by planting two year old willows at 2.0m × 2.0m spacing and dividing the main plot into sub-plots of size 8m × 2m each with 5 replications in randomized block design (RDB). The intercrops of sorghum and maize were maintained at 20cm × 10 cm spacing and supplied with recommended doses of fertilizers. The economics of the willow plantation intercropped with fodder crops was compared with sole willow farming by the benefit-cost ratio and net present worth. The study revealed the differential behaviour of Salix alba regarding growth parameters (height, diameter and girth) by different intercrops and various fodder intercrops with respect to yield, above ground biomass, dry matter production and soil nutrient status (pH, organic carbon, available nitrogen, phosphorus and potassium). The willow based silvopastoral system was estimated to have benefit-cost ratio of 2.71 with maize and 2.68 with sorghum, while as sole crop the willows accrued a benefit-cost ratio of 2.66. The study is useful in discovering growth of willows, productivity of fodder crops and soil nutrient status under various silvopastoral agroforestry systems for maximizing economic gains. The findings envisaged evidences in favour of adopting willow based silvopastoral agroforestry instead of sole tree farming and the knowledge of interactions will be helpful in proper management of the system for sustained multiple productions.

Increasing system productivity in a planned way is an important base for attaining food security, where bringing marginal land like Charland under intensive crop cultivation is highly desirable. The field trial was conducted in the Charland of the Jamuna River under Saghataupazilla of Gaibandha during 2017- 18 & 2018-19 to increase the productivity and profitability through the development of three crops-based improved cropping patterns instead of the local practice (double-crop). Three crops based improved cropping pattern namely Millet (BARI Kaon-2)-Jute (O-9897)-T. Aman (Gainja) was compared with the existing cropping pattern of Millet (Local)-Fallow-T. Aman (Gainja). The experiment was laid out in six dispersed replications maintaining RCB design. The introduced improved cropping pattern produced the higher system productivity based on rice equivalent yield, REY (12.95 t ha-1), than the existing cropping pattern (4.20 t ha-1), which is three times higher than the existing pattern. Total field duration and turnaround time were 323 and 42 days, respectively in improved pattern and 215 and 150 days, respectively in the existing pattern, which revealed that 108 days more could be made productive through the introduction of improved cropping pattern. The alternate pattern increased production efficiency and land-use efficiency by 35% and 30%, respectively than that of the existing cropping system. The gross margin was also three times higher in the improved cropping pattern (1, 41,600 Tk ha-1 yr-1) compared to the farmers’ existing cropping pattern (38,350 Tk ha-1 yr-1). The marginal benefit-cost ratio (MBCR) was calculated 2.44 in an improved cropping pattern over the existing cropping pattern. The inclusion of an extra one crop (Jute) in the existing cropping pattern and replacement of the local millet variety by high yielding variety (BARI Kaon-2) could play a significant role to increase the system productivity as well as profitability in the Charland of Saghata, Gaibandha.

Abstract Inherently poor soil fertility and non-adoption of fertilizer recommendations based on soil test and yield targets by farmers limit the productivity and profitability from monsoon rice in Bangladesh and much of South Asia. In the Level Barind Tract (LBT; AEZ-25) and the High Ganges River Floodplain (HGR; AEZ-11) agro-ecological zones (AEZs) of Bangladesh, monsoon (aman/kharif) season transplanted rainfed rice (known as T. aman rice) is grown in large areas after maize, wheat and/or mungbeans, with residues of each crop removed from the field after grain harvest. This results in lower grain yield and lower profits in these AEZs as compared with other AEZs. Nutrient management, based on soil test, yield targets, or integrated use of inorganics and organics for each AEZ together with retention of crop residue, has the potential to increase rice yield, reduce production cost and increase income. With this hypothesis, this study was conducted to determine the optimum nutrient management practices for achieving higher yield, maintaining apparent soil nutrient balance, and obtaining high profits from monsoon rice. Twelve nutrient management options were evaluated, of which the first six were: (i) 80-16-44-12-2 kg ha-1 of N, P, K, S, Zn respectively for a high yield goal (T1; ‘HYG’); (ii) 56-12-32-8- 1.5 kg ha-1 respectively for a medium yield goal (T2; ‘MYG’); (iii) 65-13-32-9-2 kg ha-1 respectively plus 5 t ha-1 cowdung as integrated plant nutrient management system (T3, ‘IPNS’); (iv) 67-14-41-9-2 kg ha-1 respectively as a soil test-based fertilizer management strategy (T4; ‘STB’); (v) 40-9-11-0-0 kg ha-1 respectively as per farmers’ practice (T5; ‘FP’) and (vi) 0-0-0-0-0 kg ha-1 as a control (T6; ‘CON’). The remaining six treatments were the same as above but each also included the crop residue incorporation (CRI), i.e., (vii) T7, ‘HYG+CRI’; (viii) T8, ‘MYG+CRI’; (ix) T9, ‘IPNS+CRI’; (x) T10, ‘STB+CRI’; (xi) T11 ‘FP’+CRI’; and (xii) T12, ‘CON+CRI’. In both AEZs, STB plus CRI resulted in the highest rice yield (p≤0.05) followed by ‘STB’ and ‘IPNS+CRI’. In comparison with ‘FP’ and ‘CON’, each without CRI, balances were positive (p≤0.05) for P, S, Zn and B but were negative for N and K in ‘HYG’, ‘MYG’, ‘IPNS’ and ‘STB’ with or without CRI. In both AEZS, STB nutrient management had the highest (p≤0.05) net returns (526 & 487 US$ ha-1, respectively), highest benefit cost ratio (BCR; 3.54 & 3.36) and highest marginal benefit cost ratio (MBCR; 10.47 & 10.19). These were followed by STB+CRI’ and ‘IPNS’, while they were lowest (p≤0.05) for CON and FP. We recommend that nutrient application, based on soil test with incorporation of mungbean residue, followed by IPNS, could be the best strategies for achieving high yield, improving soil fertility and for fetching a higher profit from monsoon rice in Bangladesh and similar soils and growing environments of South Asia.

CORRECTION: Due to a number of formatting and layout issues, the PDF of this paper was replaced on 10th October 2016. The page numbers of this paper have changed from 35-44 to 37-46.Adoptions of new crop establishment methods, changing management practices and inclusion of new crops in the rice-wheat cropping system are very important for maintaining and increasing system productivity. Experiments were conducted at the Bangladesh Rice Research Institute, Gazipur and farmers’ fields in Chuadanga during 2002-03 to evaluate the performances of rice, wheat and mungbean in bed planting and to evaluate the system productivity of Rice-Wheat-Mungbean cropping pattern. Wheat-Mungbean-Direct seeded rice (DSR), Wheat-Mungbean-Transplant rice (TPR), Wheat-Fallow-DSR and Wheat-Fallow-TPR cropping system under bed planting and conventional methods were evaluated. Grain yields of wheat, mungbean, rice and rice equivalent yield (REY) under bed planting were significantly higher (25.41, 40.91, 13.00 and 21.12%, respectively) than the conventional method. The Wheat-Mungbean-Rice cropping pattern produced significantly greater REY (38.25%) than Wheat-Fallow-Rice cropping pattern. Total variable cost was lower (17.33%) in bed planting than conventional method. Gross return, gross margin and benefit-cost ratio of Wheat-Mungbean-Rice cropping system in bed planting were higher (14.43, 40.99 and 38.52%, respectively) than the conventional method.Bangladesh Rice j. 2015, 19(2): 37-46

A field experiment was conducted during kharif seasons of 2010 and 2011 to find out the suitable integrated nutrient management (INM) package for successful blackgram production in eastern part of Uttar Pradesh. The results indicates that significantly higher grain (959 kg ha-1), stover (2479 kg ha-1) and biological (3438 kg ha-1) yields and harvest index (27.9%) of blackgram were recorded with the application of soil test based NPK+10 t FYM ha-1+ Rhizobium + 30kg S ha-1+ 1kg Mo ha-1 over rest of the treatments. With regards to economics, soil test based application of NPK + 10t FYM ha-1 + Rhizobium + 30kg S ha- 1+ 1kg Mo ha-1 resulted in highest gross returns (44,580 ha-1), net returns (26,519 ha-1) and benefit: cost ratio (2.27) over other nutritional treatments. Similarly, integration of FYM, NPKSMo with Rhizobium significantly enhances the nitrogen (3.98% and1.55%), phosphorus (0.53% and 0.27%), potassium (2.52% and 3.53% ), sulphur (0.39% and 0.31%), and molybdenum (4.25 mg kg-1 and 3.59 mg kg-1) contents in grain and stover of blackgram over control, respectively.

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.

Soils of Cambodia are low in fertility and conventional rice cultivation destroys any structure that they have. Usage of inorganic fertilizers is low and farmers are encouraged to use animal manure. Much of the research conducted on crop responses to manure is based on trials where unrealistically high application rates have been used so the farmers are given false hopes as to what they might achieve through its use. Little response curve data exists on which to base fertilizer rate recommendations and general recommendations have been formulated for the different soil groups. An economic analysis comparing the general recommendation with site specific nutrient management (SSNM) recommendations has been made on the results of a published experiment and shown substantial increases in both profitability and benefit/cost ratio in using the SSNM recommendations on four soil types. Cambodian farmers, like many in the developing world, have to be careful with their limited cash resources in purchasing plant nutrients and more attention need to be paid to producing profitable and reliable fertilizer and manure recommendations.

A fixed plot field experiment was conducted during two consecutive years (2010-12) at Farm Research, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, to find out the suitable integrated nutrient supply (INS) practice for improving the soil health, yield and profitability of blackgram in Eastern Indo Gangatic plain zone of India. The results indicated that significantly higher grain (948 and 971 kg ha-1), stover (2433 and 2525 kg ha-1), biological (3381and 3496 kg ha-1) yields of blackgram were observed with the application of soil test based NPK+10 t FYM ha-1 + Rhizobium + 30 kg S ha-1 + 1 kg Mo ha-1 over rest of the treatments.With regards to soil fertility after crop harvest, soil test based application of NPK + 10 t FYM ha-1 + Rhizobium + 30 kg S ha- 1+ 1 kg Mo ha-1 resulted in the highest soil available N (223 and 228 kg ha-1), P (21.17 and 22 kg ha-1), K (244 and 247.60 kg ha-1), S (19 and 19.78 kg ha-1) and Mo (0.30 and 0.33 mg kg-1) over other INM treatments. Similarly, soil test based application of NPK + 10 t FYM ha-1 + Rhizobium + 30 kg S ha- 1+ 1 kg Mo ha-1 recorded maximum gross returns (Rs.38584 and 50576 ha-1), net returns (Rs.20624.52 and 32415.09 ha-1) and benefit: cost ratio (2.15 and 2.78) over other nutritional treatments. Hence, study suggested that grower should follow soil test based application of NPK along with 10 t FYM ha-1 + Rhizobium + 30 kg S ha- 1+ 1 kg Mo ha-1 for fetching higher profitability from black gram cultivation in Eastern part of Indo Gangatic plains.

With limited research supporting local nutrient management decisions in North Carolina grape (Vitis vinifera) production, field studies (2015–17) were conducted to evaluate late season foliar nitrogen (N) application on leaf and petiole N concentration and yeast assimilable N (YAN) in the fruit. Foliar urea (1% v/v) was applied at different rates and application times beginning pre-and post-veraison. Compared to soil applied N, late season foliar N substantially enhanced petiole N and grape YAN. Smaller split N applications were generally more effective in increasing YAN than single larger N rates. These data demonstrate the value of assessing plant N content at full bloom with petiole N analysis or remote sensing to guide foliar N management decisions. Additional field studies (2008–11) were conducted to evaluate pre-bud soil applied phosphorus (P) and potassium (K) effects on petiole P and K nutrient status. Fertilizer P and K were initially broadcast applied (0–896 kg P2O5 ha−1; 0–672 kg K2O ha−1) prior to bud-break in 2008–09 and petiole P and K at full bloom soil test P and K were monitored for three to four years after application. Soil test and petiole P and K were significantly increased with increasing P and K rates, which subsequently declined to near unfertilized levels over the sampling time depending on site and P and K rate applied. These data demonstrate the value of annually monitoring petiole P and K levels to accurately assess plant P and K status to better inform nutrient management decisions.
