Abstract/ Executive Summary:

Objective of this study was to refine the technology through inclusion of recent wheat and mungbean variety for increasing the agro-economic productivity of rice-wheat-mungbean cropping system. This activity was initiated during November 2005 with wheat crop in 15 plots, 6 in Borai under Jhenaidah Sadar Upazila of Jhenaidah district; 6 in Patikabari under Kushtia Sadar Upazila of Kushtia district and 3 in Jolibila under Chuadanga Sadar Upazila of Chuadanga district.The agro-economic productivity of Wheat (Shatabdi)- Mungbean (BARI mung-6) - T. Aman (BR11) cropping pattern was 89% higher than existing Wheat (Kanchan)-Fallow- T. Aman (BR11) cropping pattern in rice-wheat ecosystem. This cropping pattern may be a profitable option for the farmers in rice-wheat ecosystem.

Keywords: Agro-economic productivity, Existing cropping pattern, Improved cropping pattern, Rice-wheat system

Program Area: Farming System

Non-commodity: Cropping pattern

Objectives:

To refine the technology through inclusion of recent wheat and mungbean variety for increasing the agro-economic productivity of rice-wheat-mungbean cropping system.

Methodology:

This activity was initiated during November 2005 with wheat crop in 15 plots, 6 in Borai under Jhenaidah Sadar Upazila of Jhenaidah district; 6 in Patikabari under Kushtia Sadar Upazila of Kushtia district and 3 in Jolibila under Chuadanga Sadar Upazila of Chuadanga district. Participating farmers and their plots were selected based on criteria related to the cropping systems. Two plots of each farmer were selected recommended Wheat (Shatabdi)- Mungbean (BARI mung-6)- Rice (BR11) and existing Wheat (Kanchan)-Fallow-Rice (BR11) cropping patterns. One crop cycle is completed in Aman 2006. The total productivity was compared in terms of rice equivalent yield (REY). A simple economics was done to evaluate the total productivity of the cropping system.

Achievement/Findings:

The average grain yields of wheat, mungbean, rice for improved cropping patterns are 3.20, 1.70, 5.53 t/ha, respectively. The REYs for improved cropping patterns and existing cropping patterns are 16.01 and 8.52 t/ha, respectively. The wheat variety Shatabdi produced higher grain yield in all the locations. The recent mungbean variety, BARI mung-6, also gave high yield and the performance was very good. Yield of T. Aman rice was similar in both the patterns. The REY of Shatabdi-BARI mung-6-BR11 was much higher than existing Kanchan-Fallow-BR11 cropping pattern. Economic analysis showed that instead of high TVC, Shatabdi-BARI mung-6-BR11 cropping pattern resulted much higher gross return, gross margin and BCR than the existing pattern. The results indicated that the refined cropping pattern may be a profitable option to existing pattern for the farmers in rice-wheat ecosystem.
