Abstract/ Executive Summary:

The experiments were conducted at the Pulses Research Centre, Ishurdi, Pabna, Bangladesh during the 2005-06 and 2006-07 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. Crop compositions used in the experiments were monsoon-rice (cv. BRRIdhan-32 BRRIdhan-39 and BINAdhan-4) followed by pulses (grasspea, chickpea and field pea) followed by spring-rice (cv. BRRIdhan-28 BRRIdhan-29 and BINAdhan-6). Based on 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 rice grain, 3.25 t/ha (green vegetable) + 18.1 t/ha (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 $1705/ha/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.

Start Date: 10-07.-2004

End Date: 08.02.2006

Program Area: Farming System

Commodity: Rice

Objectives:

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.

Methodology:

A field experiment was conducted for two consecutive years of 2004-2005 and 2005-2006 on Calcareous Gray Food Plain soils at Pulses Research Centre, Ishurdi, Pabna, Bangladesh. The experimental soil was clay loam in texture having pH 7.5, containing organic matter 1.2%, total N (%) 0.063, K 12μg/ml, S 15μg/ml & Zn 1.9μg/ml. Season wise, experiment was laid out in RCB design with five replications. Second crop, relay pulses, were sown in the monsoon rice plots in such a way, that every pulses were placed in every rice varieties’ plot. After the harvest of pulses for vegetable and forage, third crop of spring rice was placed in the pulses plot in the same way. First crop, transplant (T) aman rice i.e. monsoon rice (var. BR32, BR39 and BINAdhan-4), second crop, winter pulses (Lathyrus var. BARI Khesary-1, Chickpea var. BARI-chhola-5 and Field pea var. Norail local) for vegetable and forage and third crop, Boro rice i.e. spring rice (var. BR-28, BR-29 and BINAdhan-6) were used in the experiment. The unit plot size was 5m x 4m. Soil samples were collected during start and compilation of the two years cycle experiment and chemically analyzed.

1.	Budget: Fifty thousand only

Total Budget (Tk.) : Fifty thousand only

Achievement/Findings:

In this study, BINAdhan-4 - field pea (as vegetable + fodder) - BINAdhan-6, cropping pattern combindly (3 crops) produced the highest net return of Tk. 141548/ha/year equivalent to $1705/ha/year (1 $ = Tk. 83.00). Thus, the cropping system consisting of monsoon rice (BINAdhan-4) followed by relay crop of field pea (for vegetable & fodder) and spring rice (BINAdhan-6) appears to be most appropriate in terms of food, forage & vegetable production and net returns for resource poor-farmers in Bangladesh. This technology has also generated job opportunities for rural women to pick the green vegetable .of pea. The poor farmers of Bangladesh are using this technology; as a result, fallow lands are bringing under cultivation without hamper of existing crops and farmers are also getting more benefit from less land.
