In two years trial at multi location testing site, Netrakona, Bangladesh with 8 different fertilizer and straw incorporation treatments positive yield and economic response. Treatment with 2/3 straw + recommended fertilizer for moderate yield goal gave the highest grain (4.90 t ha-1) and straw (5.46 t ha-1) yields followed by T6 i.e., the recommended fertilizer for high yield (4.74 t ha-1 grain and 5.32 t ha-1 straw). Like grain and straw yields highest gross return (TK.37030 ha-1), return above variable cost (TK.26127 ha-1) and benefit cost ratio (3.40) were obtained from T3.
