In this study attempts were made to identify the areas of single animal ploughing (SAP) in Bangladesh, causes of its localization and the socio-economic constraints hindering the expansion of the system. To determine the areas of single animal ploughing, 123 upazilas of 15 districts were surveyed. Of them, 16 upazilas were found heavily engaged with this system. A detailed investigation of 469 SAP and 439 double animal ploughing (DAP) farmers revealed that there was significant difference between the two systems in respect of cost of production and yield per unit of land. The benefit/cost (B/C) ratio was higher in SAP system. However, no significant difference was observed in respect of time required for ploughing, intensity of cropping, cost of implements, and cost of repairing implements (except yoke). The study recommends for expansion of SAP system in areas where buffaloes are concentrated. Fro this purpose, logistic and institutional supports need to be made available.

In this study an attempt was made to evaluate the economics of dairy farming in selected areas of Bangladesh. Data from 20 randomly selected farms were collected by survey method. Results show that cross-bred cows were more in number (2.55) in those farms than that of local cows (0.65). The number of cross-bred cows increased as the farm sizes increased. The production of milk per cross-bred cow was higher (5.66 litres) than the local ones (2.23 litres). Highest (5.74 litres) milk yield per cross-bred cow was recorded in large farms. The average lactation period for crossbred cows was higher (304 days) than the local cows (210 days). In production cost of farms, concentrates took the highest share (35.19%) followed by labour charges (23.64%). The production cost and gross returns for mini dairy farms were higher in large farms (TK. 183,005 and TK. 187,544, respectively), compared to medium and small farms. The benefit-cost ratio of all farms was 1 : 1.03, indicating that mini dairy farming is economically profitable. In addition, each farm created an annual employment opportunity of 649.70 man-days which was met by both male and female labourers. The small farms employed more female family labourers while the large farms depended more on hired labourers. The expansion of dairy farming with cross-bred cows is suggested for accelerating income and employment opportunities in rural Bangladesh.

Asia Triple HIn this study an attempt was made to determine the cost of producing fodders at Savar Dairy Farm (SDF). For this purpose, all seasonal fodders, such as Maize, Jowar, Cowpea and Oat and all perennial fodders, such as Para and Napier were studied. The highest acreage of land was allocated to high-land Para (33.8%) and the lowest acreage (2.7%) was devoted to Cowpea. Jowar attained the highest yield (74.2 tons) per hectare and Maize attained the lowest yield (25.8 tons/h). The highest cost per hectare was attributed to Jowar (TK. 20944.18) while the lowest cost was attributed to low-land para (TK. 10349.86). The cost of production of fodder per kilogram was the highest (TK. 0.66) for Maize and the lowest for Oat (TK. 0.24). The cost of production of low-land Para was much lower than that of high land Para. The per kilogram cost of silage production was the highest (TK. 0.71) for Maize and the lowest (TK. 0.31) was for Napier. The gross return analysis further showed that the highest net margin and B:C ratio were observed for Napier followed by Low-land Para, Jowar, Oat, Cowpea, High-land Para and Maize. Therefore, those fodders whose B:C ratios and yield/ha were higher should be allocated more area of land to stimulate increased returns to SDF in the future is suggested.

This study was conducted to compare the of rearing native and cross-bred dairy cows and returns received from them. For this purpose, 144 cows of 132 household from 24 villages were randomly selected. of them, 96 were native cows and 48 were cross-bred cows. The study revealed that among the structure of cost components, labour charge occupied the major share in the total cost of milk production per litre. The total cost of rearing native and cross-bred cows was Tk. 14,155 and Tk. 19,854 per annum, respectively. The average net cost of milk production per litre was Tk. 14.12 for native cows and Tk. 0.52 and for cross-bred cows were Taka 3.40. The benefit-cost ratio of milk per litre was higher (1:1.33) in cross-bred cows than native ones (1:1.04). The study further showed that in comparing with bulk line cost, the price of milk per litre received by the farmers was higher in cross-bred cows than native cows. Therefore, the study recommends dairying with cross-bred cows as encouraging and viable commercial enterprise in Banfladesh.

미국 농무성은 방글라데시의 Pirganj군과 Kurigram군에 작물재배기술을 보급하여 농민들의 소득을 향상시키고 작물의 수량을 제고하여 농민들의 식량을 자급 할 수 있도록 하기 위하여 2008년부터 2012년까지 4개년간 기술지원기금US$ 571,270을 제공할 계획이다. 이 사업의 주목적은 948ha, 임야개간 52ha 및 유휴지 345ha를 개발하고 농업생산기술을 지도 보급함으로써 농산물의 생산성을 제고시키고 가난한 1,059농가와 5,305명의 농촌농민들의 사회 경제적 생활조건을 개선시키는 것이다. 이 사업을 위하여 방글라데시의 미작연구소, 방글라데시 농업연구위원회, Rangpur Dinajpur 농촌 서비스 센터 및 농민단체들이 참여 하고 있다. 본 연구의 목적은 (1) 미곡, 밀, 옥수수, 엽연초 및 사탕수수의 생산성을 구명하고, (2) 작물 별 생산비와 소득을 추정하며, (3) 투입 산출물간의 상호관계를 구명하여 (3) 본 사업의 총 수익과 총 사업비를 비교함으로써 본 사업의 재무적 타당성 지표인 FIRR,NPV,B/C Ratio를 구명해 보고자 한다. 본 사업의 연간 순기대총편익은 US$ 33,028이다. 농산물 생산액의 총 증가액은 US$ 219,959이며 총 생산비증가액은 US$186,931로 추정되었다. 본 사업의 재무수익률은 경제분석기간을 15년으로 가정했을 경우 재무수익률(FIRR)이 26.15%로 추정되었으며, 이는 방글라데시의 할인율 10%보다 2.6배가 높게 나타났다. 방글라데시의 할인율을 10%로 볼 경우 B/C Ratio는 1.077이며 NPV는 US$ 101,663로 추정되었다. 따라서 본 사업은 방글라데시의 농촌경제를 활성화 시키고 가난한 농민들의 복지를 증대시키는데 있어 매우 중요한 농업정책으로써, 방글라데시의 타 지역에도 확대 보급함은 물론 재정적 지원을 지속해 나가야 할 것으로 판단된다.

This experiment was conducted to find the most suitable crop establishment method and weed management practices for transplanted aman rice in Bangladesh. Rice variety Bangladesh Rice Research Institute (BRRI) dhan44 was used as planting materials where three crop establishment methods ($T_1$: direct wet seeding by drum seeder; $T_2$: hand broadcasting; $T_3$: transplanting) and four weeding options ($W_1$: Hand weeding (HW); $W_2$: BRRI weeder+HW; $W_3$: Herbicide+HW; and $W_4$: no weeding) were tested. Among the crop establishment methods, the highest grain yield ($5.12t\;ha^{-1}$) was obtained with the $T_3$, while the highest benefit cost ratio (BCR) of 2.08 was found in $T_2$. In case of the weed management method, $W_1$ showed superior results on the plant $density/m^2$ (139.66) at 60 days after transplanting (DAT), grain yield ($4.97t\;ha^{-1}$), and BCR (2.03). On the other hand, the highest plant dry matter (36.20 g) at 60 DAT and the highest yield ($6.10t\;ha^{-1}$) were obtained in a $T_3W_1$ combination. The results of this study show that the productivity of rice during aman season could be most significantly increased with the use of transplanting ($T_3$) alone, hand weeding ($W_1$) alone, or a combination of the two methods ($T_3W_1$).
