An experiment was conducted to evaluate the effect of tillage practices and nitrogen rates on the %N content in grain, straw and N uptake by grain, straw, plants in rice var. Binasail. The %N content in grain, N uptake by grain and total N uptake by plant were significantly influenced by different tillage practices. Maximum N content in grain (1.12 %), N uptake by grain (34.54 kg/ha-1) and total N uptake by plant (43.23 kg/ha-1) were observed in 20 cm deep tillage treatment (T2). Minimum N content in grain (1.09 %), N uptake by grain (26.87 kg/ha-1) and total N uptake by plant (35.41 kg/ha-1) were found in no tillage treatment (T not). The nitrogen content (%) in grain and straw, N uptake by grain and straw and total N uptake by plant were also significantly influenced by different rates of nitrogen application. The maximum N content in grain (1.17 %) was recorded in no nitrogen (N 0) and the minimum (1.04 %) with the application of 105 kg N ha-1 (N3). The interaction effect of tillage operations and nitrogen application on %N content in grain, straw and total N uptake (kg/ha-1) by plant found to be significant.
