Field experiments were conducted during Kuruval season (June to September) 1996 and 1997 on hybrid rice ADTRII to study the effect of four nitrogen levels (0.75.150 and 225kg ha'') and three seed rates in nursery (10.20 and 30g m). The results revealed that there was significant increase in plant haight, dry matter accumulation. productive tillers/m². panicle weight and grain yield with an increase in the level of nitrogen from 0 to 150 kg/ha further increase in N rate upto 225 kg ha'did not show significant increase. Straw yield was found significant upto 225 kg N/ha. The seed rate 10 g/m² recorded the highest grain yield. followed by 20 and 30 g/m². The growth and yield attributes except plant height were significantly higher with 10 g/m² of seed rate than the other rates.
