Abstract
In a fertilizer management experiment conducted during 1988 crop seasons with
different levels of N, P and K, it was observed that 50 kg N/ha was sufficient for the rice cultivar
Culture 1727 from the point of view of economics and nitrogen use efficiency, in laterite soil with
low available nitrogen status. Application of different levels of N, P and K did not show any
marked effect on the grain and straw yield. Plant nitrogen content decreased and uptake increased
up to 50 per cent flowering. Maximum nitrogen uptake was observed in between 30 to 40 days
after transplanting. Better utilization of nitrogen was observed during the second crop season
(Oct-Jan).
