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.

The "System of Rice Intensification"(SRI) represents a sustainable alternative to improve household yields and incomes. This study aimed to evaluate the yields and the profitability of the SRI and the Traditional Practices (TP) in Ziguinchor district, Senegal. A directed sampling based on criteria for selecting the system used and the cultivated varieties common to both systems was applied to collect the yield parameters and yields of paddy rice. Thus, 18 producers in the Badiate, Essyl, and Fanda sites were selected, nine per system and four 1 m2 yield squares were installed in each selected producer plot. A total of 72 yield squares, 36 per system, were installed, and an individual questionnaire was randomly administered to 55 producers using at least one of the systems to collect data on rice production and costs. The yield parameters including the number of fertile tillers per m2, the number of spikes, the weight of the 1000 grains are significantly higher (p<0.05) in the SRI including yield compared to the traditional system. Transplanting density and plant duration are higher in TP (26±5.6 plants/m2 and 26 days) than in SRI (16±0.4 plants/m2 and 16 days). The lower the transplanting density, the higher the yield parameters and the yield. The economic profitability, determined based on the benefit/cost ratio, is higher in SRI (1.5) than in TP (1.2). The SRI required a lot of technicality in its implementation and generated more cost of production. However, SRI was more productive and economically more profitable than the traditional system.

Efficacy and profitability of insecticidal management practices using different insecticides were tested against insect pests of mungbean at Pulses Research Center, Ishurdi, Pabna, Bangladesh during two consecutive seasons of kharif-1 2013 and 2014. Insect infestations were reduced significantly by the application of synthetic insecticides. Spraying of Imidachloprid (Imitaf 20 SL) @ 0.5 ml/l of water showed the best efficacy in reducing flower infestation and thrips population followed by Fipronil (Regent 50 SC). Spraying of Thiamethoxam + Chlorantraneliprol (Voliam flexi 300 SC) @ 0.5 ml/l of water showed the best efficacy in reducing pod borer and flea beetle infestations. Spraying of Fipronil (Regent 50 SC) performed highest efficacy against stemfly infestation. The yield and the highest net return were obtained from Voliam flexi 300 SC, the highest benefit was obtained from Regent 50 SC treated plots. This might be due to the higher cost of Voliam flexi that reduced the profit margin and showed the lower marginal benefit cost ratio (MBCR) compared to Regent. Therefore, considering the efficacy and benefit, spraying of Fipronil (Regent 50 SC) @ 0.5 ml/l is the most profitable insecticidal management approach against insect pests of mungbean followed by Imidachloprid (Imitaf 20 SL) at the same dose.Bangladesh J.

Okra is one of the most important summer vegetables in South Asian countries including Nepal. However, the damage by insects like Jassid (Amrasca biguttula Ish.) and whitefly (Bemisia tabaci Guen) has resulted in significant reduction of its production. An experiment was conducted based on intercropping taking okra (Abelmoschus exculentus L. Moench) as the main crop in Arghau, Lekhnath-27, Kaski, Nepal from March 4 to May 24, 2018. The intercrops used were coriander (Corriander sativum), carrot (Daucas carota), fennel (Foeniculum vulgare) and parsley (Petroselinum crispum). The population of jassid and whitefly was recorded from three leaves representing the different strata (bottom, middle and top) of the vegetative parts; and related yield parameters were also observed to correlate with the level of population incidence of these pests. Least numbers of jassids (5.50±0.29, 6.94±0.43, 8.00±0.41 and 3.69±0.76) were observed respectively at 30, 40, 50 and 60 days after sowing (DAS) in okra+ coriander. Likewise, okra + coriander intercropping was effective in inhibiting the population of whitefly (7.50±0.59, 8.56±0.19, 10.25±0.66 and 7.06±0.42) at 30, 40, 50 and 60 days after sowing (DAS) respectively. In contrary, the highest number of jassids and whiteflies were observed in okra + parsley and control (okra only). Both pod length (cm) and yield (t/ha) were the highest (17.92±0.57 and 28.20±0.49 respectively) in okra + coriander and were the lowest (16.42±0.21 and 27.58±0.39 respectively) in okra + carrot. The benefit-cost ratio was in order okra + coriander > okra + carrot > okra + fennel > okra + parsley > control (okra only). Among the different intercrop combinations, the okra + coriander was found most effective that could be suggested as one of the alternative strategies to limit the population of pests; jassid and whitefly in okra.

A field experiment was conducted under late planted lowland situations during wet seasons of 2012 and 2013 at Jorhat to evaluate the performance of 3 late planted sali (kharif) rice varieties (Prafulla, Gitesh and Monoharsali) under 3 planting dates (10, 20 and 30 September) with 2 types of seedling (Nursery seedling and double planted seedling). Results revealed that delaying planting dates from 10 September to 30 September significantly and consistently reduced both grain and straw yields along with all the yield attributing characters during both the years. On an average, the grain and straw yield reduction being 58.3 and 19.3 per cent, respectively. Among the varieties tested, rice variety ‘Monoharsali’ outyielded the variety, ‘Prafulla’ and ‘Gitesh’. Double planted seedlings of 60 days (30 + 30 days) old recorded significantly higher yields and all the yield attributes over the use of 60 days nursery seedling. The highest net return and benefit-cost ratio was recorded when rice variety, ‘Monoharsali’ was transplanted on 10 September using 60 days (30 + 30 days) double planted seedling.

The experiment consists of the following treatments: T1: Nitro 505EC (Chloropyrifos+Cypermethrin) @ 2 ml/L of water at 10 days interval; T2: Casper 5 SG (Emamectin Benzoate) @ 2gm/L; T3: Voliam Flexi (Thiamethoxam+Chlorantraniliprole) @ 0.25 ml/L; T4: Tapnor 40 EC (Dimethoate) @ 2.0 ml/L; T5: Allion 2.5 EC (Lamda-Cyhalothrin) @; T6: Admire 200SL (Imidachorpid) @ 0.25 ml/Land T7: Control. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The lowest number of whitefly infestation per plant in the vegetative stage (4.18) and reproductive stage (2.13) was recorded from T6 treatment, whereas the highest (14.44) and (8.10) was recorded from T7 treatment in respective stage. Thrips infestation was higher (6.32) per 5 flower was recorded from T7 treatment whereas lower infestation (1.88) per 10 flower was recorded from T6. The lowest yield per hectare (1.27 ton) was found in T7 and lowest benefit cost ratio (4.16) was found in T5 whereas highest yield per hectare (1.53 ton) was found in T6 and highest benefit cost ratio (12.81) was found in T3 treatment. Among the management practices for controlling whitefly and thrips of mungbean Admire 200SL @ 0.25 ml/L of water was more effective which was followed by Voliam Flexi (Thiamethoxam+Chlorantraniliprole) @ 0.25 ml/L of water Farmers should use Admire 200SL(Imidachorpid) @ 0.25 ml/L of water at 10 days interval for controlling whitefly and thrips in mungbean.

The integrated use of chemical and organic fertilizers can help in sustainable and environmentally sound nutrient management of soils. A study was conducted in the farmer’s field of Godaghari, Rajshahi from February to May 2012 to investigate the effect of integrated nutrient management on nutrient uptake by rice cv. NERICA 10 and economization of inputs. Six treatments viz. T1 = Control, T2 = RFD for MYG + cowdung @ 5 t ha-1, T3 = RFD for HYG, T4 = RFD for HYG + cowdung @ 5 t ha-1, T5 = RFD for HYG + cowdung @ 5 t ha-1 based on IPNS, and T6 = RFD for HYG + 10% excess fertilizer of HYG were used. The experiment was laid out in a randomized complete block design with three replications. Results showed that the uptake of N, P, K, S, Ca and Mg by both grain and straw of rice were statistically significant due to use of integrated nutrient management. The highest nutrient uptake was recorded from the treatment T5 and the lowest value was obtained from control. Combined application of cowdung @ 5 t ha-1 along with recommended chemical fertilizers based on IPNS was more economic compared to other treatments because maximum benefit cost ratio was calculated from this treatment. The overall results suggest that integrated nutrient management can be used as an alternate option of chemical fertilization to achieve maximum yield, nutrient uptake and cost of return for rice cv.

Bamboo is proven to provide multi-benefits from the aspects of production, ecology and socio-economic. However, bamboo is still not fully developed. People tend to replace bamboo with wood species which are considered to be more profitable, one of them is sengon. The purpose of this study was to analyze bamboo management practices carried out by farmers and compare between sengon and bamboo cultivation which is more financially profitable. Financial analysis conducted includes: Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR). Analysis of market aspect and social aspect using the Market Analysis and Development (MA&D) method. The sensitivity analysis is carried out on the condition of fixed income while costs increase by 10% and 30% and fixed costs while income rises by 10% and 30%. The analysis included the analysis of market aspect and social aspect. The results of the financial analysis showed that the cultivation of petung bamboo with a spacing of 6x6 meters gave the highest yield with NPV value of IDR330.329.538, BCR 29.10 and IRR of 25.18%. Nevertheless; looking at market and social aspects, bamboo and sengon can be developed in agroforestry to ensure sustainability and continuity of income for farmers. Bamboo and sengon cultivation business is feasible to be conducted because the high demand which cannot be met from the existing sources.
