  A field experiment was conducted during the Kharif season (June to November) of 1998 at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh to study the effect of point placement of urea super granule (USG) and broadcasting prilled urea (PU) as sources of N in Transplant aman rice. One hybrid variety (Hybrid rice 6201) and one modern inbred variety (BRRI Dhan 32) were included in the experiment. USG and PU were applied at 40, 80, 120 or 160 Kg N ha–1. A control (no N) treatment was also included in the experiment. Hybrid rice 6201 produced significantly longer panicle and higher number of total spikelets panicle–1 but showed poor performance regarding all other yield parameters. A considerable difference was noted between these two varieties in respect of spikelet sterility where Hybrid rice 6201 produced almost the double of sterile spikelets than that of BRRI Dhan 32 which ultimately led to inferior grain yield (3.25 t ha–1). On the other hand, BRRI Dhan 32 produced taller plants, higher number of effective tillers hill–1, grains panicle–1 and heavier grains which eventually contributed to higher grain yield (3.85 t ha–1). USG was more efficient than PU at all respective levels of nitrogen in producing all yield components and in turn, grain and straw yields. Placement of USG at 160 kg N ha–1 produced the highest grain yield (4.32 t ha–1) which was statistically identical to that obtained from 120 kg N ha–1 as USG and significantly superior to that obtained from any other level and source of N.

  The response of hybrid (Sonar Bangla-1 and Alok 6201) and inbred (BRRI Dhan 34) rice varieties was determined to the application methods of urea supergranules (USG) and prilled urea(PU). Grain and straw yields were highest (4.87 and 7.72t ha -1, respectively) in BRRI Dhan 34. The highest grain yield of BRRI Dhan 34 was mostly the outcome of highest number of grains panicle -1. Sonar Bangla-1 produced the second highest (4.28t ha -1) grain yield while the lowest one (3.86t ha -1) was produced by Alok 6201 which was the consequence of lowest number of grains panicle-1 and highest number of sterile spikelets panicle -1. BRRI Dhan 34 showed the best performance among the varieties studied for almost all the growth and yield characters. Grain yield was recorded the highest (4.5t ha -1) in the method of half USG + half PU at 10 and 30 DAT which maintained similarity with recommended method of USG and furrow placement of USG. BRRI Dhan 34 interacted favourably with furrow placement of USG to produce the highest grain yield.
