Abstract/ Executive Summary:

The study was conducted to determine the yield and economic consequences of two cropping patterns viz. improved cropping pattern (Wheat-Jute-T.aman rice) and farmers, pattern (Wheat-Jute-T.aman rice) through incorporation of modern high yielding varieties and improved management practices for crop production. The experiment was laid out in randomized complete block design with five dispersed replications in farmers’ condition in Faridpur during two consecutive years 2011-12 and 2012-13. Two years mean data showed that the improved management practices for the pattern provided significantly higher yield in Wheat, Jute and T.aman rice. The gross return (Tk. 265495/ha) and net return (Tk.123087/ha) of improved pattern were 9 % and 18 % higher, respectively compared to that of farmers’ pattern with only 3% extra cost. The higher benefit cost ratio, land use efficiency, production efficiency and sustainable yield index indicated the superiority of the improved pattern over the farmers’ practices.

End Date: 00-00-2013

Program Area: Farming System

Commodity: Rice, Jute, Wheat

Objectives:

The study was initiated with a view to find out the agro-economic feasibility of an improved package of technologies over the existing farmers’ practices.

Methodology:

The study was conducted at Farming System Research and Development (FSRD) site of Bangladesh Agricultural Research Institute (BARI) at Hatgobindapur, Faridpur during 2011-2013. It belongs to the Low Ganges River Floodplain Agro-ecological Zone of Bangladesh (AEZ-12). The experimental site belongs to tropical monsoon climate with unimodal rainfall. The most of the rainfall was received during the months of May to September. The annual rainfall of the study period were 1548 mm and 1623 mm. Mean annual minimum and maximum temperature was 21.55/30.96^oC and 21.28/30.83^oC, respectively. The soil was clay loam with low organic matter content (1.24%) and soil pH ranged from 7.0 to 8.1 neutral to slightly alkaline in nature. The statuses of N, P, K, S, Zn and B were very low, low, medium and low, respectively. (Table 1) General soil types predominantly include Calcareous Dark Grey soils and Calcareous Brown Floodplain soils. The improved cropping pattern (IP) was tested and compared against the farmers’ pattern (FP) with five dispersed replications under irrigated condition. Two plots of 600 m² were selected for each replication. One plot was under the improved pattern and the other one was farmers’ pattern. In the improved pattern, BARI Gom-26 and BRRI dhan39 were introduced against BARI Gom-21 and BRRI dhan33. The jute variety JRO 524 was used in both the patterns. The agronomic practices and cultural operations for crop production under improved and farmers’ practices are presented in Table 2. All field operations and management practices of both improved and farmers’ patterns were closely monitored and data were recorded for agro-economic performance. The yield differences between the practices were statistically analyzed by‘t’-test. Agronomic performance like field duration, land use efficiency, production efficiency, sustainable yield index and rice equivalent yield of cropping patterns were calculated. Land use efficiency was worked-out by taking total duration of crops in an individual cropping pattern divided by 365 days.

Achievement/Findings:

Considering higher rice-equivalent yield, net monetary return and more sustainability of the improved cropping pattern (Wheat-Jute-T.aman) with modern variety BARI Gom-26 and BRRI djan39 with improved technologies could be suggested for medium high land of the Low Ganges River Floodplain Agro-ecological Zone (AEZ-12) of Bangladesh
