The experiment was conducted to evaluate the modern photosensitive rice varieties, BR22, BR23, Binasail and an advanced line BR5226-6-3-3 and widely cultivated local variety Telosh for increasing the productivity of medium high land phase-2. BR5226-6-3-3 gave the highest grain yield of 4.14 t ha-1 followed by BR23 (3.96 t ha-1). The higher grain yields of BR5226-6-3- 3 and BR23 were associated with higher number of filled grains panicle-1 and heavier grain weight. Economic analysis indicated that cultivation of BR5226- 6-3-3 and BR23 after Boro rice gave about 36 and 31 additional gross margins than the existing local variety, Telosh.
