Description A field experiment was conducted during rainy season of 2003 at the research farm of the Indian Agricultural Research Institute, New Delhi to study the effect of N and S levels on productivity and nutrient uptake in aromatic rice. The experiment was carried out with 16 treatments combinations of 4 N levels (0,50, 100 and 150 kgha) and 4 S levels (0, 20, 40 and 60 kg/ha) in factorial randomized block design replicated thrice. Growth and yield attributes, grain, straw and biological yields increased significantly with N and S levels. The increase in grain yield due to application of 100 and 150 kg N/ha over control was 1.99 tonneslha and 1.95 ronneska and in terms of percentage increase was 49.5 and 48.5% respectively. The percentages increase in the grain yield of rice at application of 20,40 and 60 kg $/ha over the control were in the order of 6.5,7.3 and 8.8% respectively. Various N and S levels had a significant effect on N, P, K and S uptake by grain, straw and their total. Based on the total N uptake (grain + straw) there was 49.9, 63.9 and 70.4% increase in the N uptake over the control with 50, 100 and 150 kg Nka, respectively. From this field study it can be concluded that aromatic rice requires 100 kg N and 20 kg Slha for increased productivity and uptake of N, P, K and S, under transplanted puddled condition.
