Abstract/ Executive Summary:

The high-yielding modern variety (MV) rices developed by BRRI presently covers 90% of the Boro (winter rice), 25-30% of the Aus (summer rice), and 50-55% of the transplanted Aman (wet season rice) areas of Bangladesh. But, BRRI varieties are not equally adopted by the farmers in different agroecological zones (AEZs). The study was undertaken to assess the adoption rate of MV rices in different AEZs in Bangladesh and estimate the yield of MV and local rice varieties in different agroecological situation. A multi-stage random sampling procedure was adopted to collect the farm level data. A total of 46 thanas under seven AEZs of the country were selected, considering the variance of MV rice adoption rate. Data were collected from randomly selected rice farmers using a predesigned questionnaire. Among the MV rices cultivated in the T.Aman season, BR11 covered the highest area (30%) followed by Pajam (4.9%) in the 1996 T.Aman season. In the Boro season, Purbachi ranked highest coverin g 20% of the Boro area followed by the Indian varieties (12.31%). In the Aus season, Purbachi covered the highest area (19%) followed by the Indian varieties (12.59%) and BR2 (11.36%). Thus, it seems that Purbachi is popular both in the Boro and Aus seaon because of its short growth duration. The average yields of MV rices in the T.Aman, Boro and Aus seasons were, 3.30, 4.48 and 3.08 t/ha, respectively. However, BR4 yielded the highest of 3.66 t/ha in T.Aman; BR15, 5.71 t/ha in Boro; and BR9 4.09 t/ha in Aus season.

Program Area: Socio-economic and Policy

Commodity: Rice

Objectives:

To assess the adoption rate of MV rices in different AEZs in Bangladesh.
To estimate the yield of MV and local rice varieties in different agroecological situation

Methodology:

A multi-stage random sampling procedure was adopted to collect the farm level data. A total of 46 thanas under seven AEZs of the country were selected, considering the variance of MV rice adoption rate. Data were collected from randomly selected rice farmers using a predesigned questionnaire. Collected data were edited, and analyzed using simple tabular method .

Achievement/Findings:

Among all MV rices, BR11 covered the highest area (30%) followed by Pajam (5%) in the T.Aman season. The popular variety Puurbachi ranked highest in both the Boro and the Aus seasons, covering 20% and 19% of the total area, respectively. In terms of yield, BR4 ranked the highest (3.66 t/ha) in the T.Aman season. BR15 yielded the highest (5.71 t/ha) in the Boro season. BR26 and BR16 were the next higher yielders in the Boro season. In the Aus season, BR9 surpassed all other modern rice varieties.
