Four improved cropping patterns, BRRIdhan28-Fallow-BRRIdhan30, BRRIdhan28-Fallow-BRRIdhan31, BRRIdhan29-Fallow-BRRIdhan30 and BRRIdhan29-Fallow-BRRIdhan31 were evaluated in the farmers field along with the farmers` existing major cropping patterns BR14-Fallow-BR11 and BR14-Fallow-Pajam in six blocks under Sadar, Kapasia and Sreepur Upazilas of Gazipur district. Grain yields of all the alternative improved cropping patterns were significantly higher than the farmers` existing cropping patterns in each site. In all locations, pattern BRRIdhan29-Fallow-BRRIdhan31 gave higher grain yield and higher gross margin compared to other tested patterns.
