The experiment was conducted during July to December 2013 to study the effect of varieties and number of guti urea hill–1 on the yield of Transplant Aman rice where three varieties viz. Moulata, Shakorkura and BRRI dhan-51 and three levels of guti urea hill–1 viz. 0, 1 and 2 guti hill–1 were used for the present study. The factorial experiment was laid out in a split–plot design with three replications. Responses of variety had significant among the whole yield, yield. Similarly, 2 guti hill-1 recorded the tallest plant (129.0 cm), maximum effective (7.846) and total tillers hill-1 (9.112). Maximum total grains panicle–1 (128.8), highest 1000 grain weight (28.88 g), grain, straw and biological yield (5.593, 9.661 and 15.27 t ha–1, respectively) were also obtained in 2 guti hill-1. Seed quality character viz. germination, SVI, EC, protein, seedling height and dry weight had also higher (93.45%, 53.66, 37.99 μ S cm-1, 7.344, 17.10 cm and 0.2041 g 10 seedlings-1, respectively) in 2 guti hill-1. Quality character of seed had also perform better in BRRI dhan-51 with 2 guti hill-1 as well as higher germination (94.67%), SVI (54.43), EC (39.32 μ S cm-1), protein (8.00%) and seedling height (18.09 cm) were taken from this interaction. These results suggested that the variety BRRI dhan-51 and 2 guti hill–1 individually or combined would be more effective for greater yield of T aman rice.
