Abstract/ Executive Summary:

The Barind tract covers about 7728 km² in the seven districts of Rajshahi region and three districts of Rangpur region. Landscape of high Barind tract (HBT) is gently undulating. Predominant cropping pattern in HBT is rainfed T. Aman followed by fallow. Expansion of modern rice variety (MV)brought a dramatic change in annual rice production of Bangladesh. Although farmers are growing many varieties, only a few of them are popular eg, BRRI dhan28 in Boro and Aus and BR11 in Aman. The short duration Aman varieties BRRI dhan32, BRRI dhan33 and BRRI dhan39 are excellent for areas where early Rabi crop are to be grown in time. Farmers managed the lodging character of BRRI dhan32 by late transplanting after harvesting of short duration local Aus variety like Parija. After T Aus, some farmers are cultivating traditional aromatic varieties Chini Atap for high price. DAE has initiated special program to popularize fine aromatic rice varieties like BRRI dhan34, BRRI dhan37 and BRRI dhan38 which will give higher yield and higher price compared to local CHini Atap. Farmers also prefer high yielding modern rice varieties with high quality and high market price in T Aman season but disease susceptible long duration rice variety like Swarna in the HBT still exists which reduces the opportunity to establish Rabi crops using residual moisture. In Rajshahi region, BRRI dhan28 replacing Parija quickly in Aus season. Hybrid rice like BRRI hybrid dhan1, Sonar Bangla, Jagoron etc gaining popularity due to higher yield, but price and unavailability of seed is major constraint to disseminate the BRRI hybrid rice variety.
