主 题：Benefit land rice pea cropping pattern.
摘 要：The experiments were conducted at the Pulses Research Centre, Ishurdi, Pabna, Bangladesh during the 2005-2006 and 2006-2007 crop seasons to determine the economic viability of planting legumes for both vegetable and forage purposes in the fallow period between monsoon-rice and spring-rice. The objectives were to ensure better land utilization, break up the mono cropping, improve soil health, and generate extra-income for small and resource-poor farmers of Bangladesh. Crop compositions used in the experiments were monsoon-rice （cv. BRRIdhan-32, BRRldhan-39 and BINAdhan-4） followed by pulses （grasspea, chickpea and field pea） followed by spring-rice （cv. BRRldhan-28, BRRldhan-29 and BINAdhan-6）. Based on the data from two years in a pooled analyses, it was observed that monsoon-rice variety BINAdhan-4, followed by field pea （as vegetable ＆ forage） and spring-rice variety BINAdhan-6 produced the highest yields of 5.0 t ha-1 rice grain, 3.25 t ha1 （green vegetable） ＋ 18.1 t hal （forage） legumes and 7.8 t ha~ rice grain, respectively. The cropping pattern of monsoon-rice （BINAdhan-4）-field pea （as vegetable ＋ forage）-spring-rice （BINAdhan-6） gave the highest net return of USD$1,705 hal year-~ compared to other patterns with different rice varieties and chickpea and grasspea. This is a new finding, and is being practiced by farmers of Bangladesh who have enhanced their farm income substantially. This has also generated job opportunities for rural women to pick the green vegetable of field pea.
