On-farm Assessment of System Productivity of Wheat- Jute-t. Aman Rice Cropping Pattern in Sylhet Region

M.I. Nazrul
OFRD, Bangladesh Agricultural Research Institute (BARI), Bangladesh.

Abstract/ Executive Summary:

The study was conducted to determine the yield and economic performance of two cropping patterns viz. IP: improved pattern (Wheat - Jute - T. aman) + improved management practice and FP: farmer’s pattern (Fallow - T. aus - T. aman) + management practice. The experiment was laid out in a randomized complete block design with six dispersed replications at farmer’s field in Sylhet region during two consecutive years of 2013-14 and 2014-15. Two years means data showed that the pattern with improved management practices provided 31% higher yield of T. aman rice and also contributed more rice equivalent yield compared to farmers practice. Sustainable yield index, production efficiency, and land use efficiency were the maximum with Wheat- Jute- T. aman cropping system. Similarly, highest mean gross margin and benefit cost ratio were attained in improved pattern. It was concluded that farmers of Sylhet region might follow Wheat (var. BARI Gom-26) - Jute (var. CVL-1) - T. aman (var. Binadhan-7) cropping system in medium high land for higher productivity and profitability.

Keywords: Agronomic performance, Land use efficiency, Production potential, Sustainable yield index

Location: In farmer’s field under Eastern Surma - Kushiyara Floodplain

Start Date: 00-00-2013

End Date: 00-00-2015

Program Area: Farming System

Non-commodity: Cropping pattern

Objectives:

The present study was therefore, initiated to find out the agro- economic feasibility of an improved package of technologies over the farmers existing practices

Methodology:

On-farm trials were carried with out in farmer’s field under Eastern Surma - Kushiyara Floodplain (AEZ-20) which is located in between 23°58' and 24°16' north latitudes and in between 91°16' and 91°25' east longitudes of Bangladesh, during two consecutive years 2013-14 and 2014-15. This trial was conducted to with two cropping patterns viz. IP: improved pattern (Wheat - Jute - T. aman) and FP: farmer’s pattern (Fallow - T. aus - T. aman) through inclusion of modern high yielding varieties of Jute, T. aman rice as well as Wheat and improved management practices for crop production.

Annual monthly total rainfall 3821 mm was during the period 2014-15. Average maximum and minimum temperature was 31.34 and was 14.72⁰C, respectively (Fig.1). The soil was clay loam with low organic matter content (1.30%) and soil pH was ranged 5.3-6.2 acidic in nature. The status of N, P, K, S, B and Zn was very low, low, low, very low and medium, respectively. The experimental design was a randomized complete block with six dispersed replications with plot size of 500 m².One plot was under the improved pattern and the other farmer’s pattern.

In the improved pattern, wheat var. BARI Gom-26 was introduced against fallow period. The var. CVL-1 of Jute and Binadhan-7 of T. aman rice was introduced instead of BR26 and BRRI dhan33, respectively. All field operation and management practices of both farmer’s and improved pattern were closely monitored and the data were recorded for agro-economic performance. The yield differences between the practices were statistically analyzed by‘t’ test. Agronomic performance viz. land use efficiency, production efficiency, rice equivalent yield and sustainable yield index of cropping patterns were calculated by the formula.

Achievement/Findings:

Wheat - Jute - T. aman rice cropping system was found more productive, sustainable, land-use efficient, and remunerative than the existing farmers cultivated patterns under eastern Surma-Kushiyara Floodplain (AEZ-20) of Bangladesh. . Therefore, farmers of AEZ-20 could follow the Wheat (var. BARI Gom-26) - Jute (var. CVL-1) - T. aman (var. Binadhan-7) rice cropping system for higher system productivity and profitability in medium high land.
