Abstract

                                Two years data on grain yield revealed non-significant differences in the first year due to slow-release sources of N at a moderate dose of 50 kg N/ha for rice IR 20. In the second year however. IBDU was able to record the highest grain yield of 5040 kg/ha. The split application of N at 25 kg/ha at tillering and another 25 kg/ha at panicle initiation stage and pre-plant application of SCU at 50 kg N/ha gave similar grain yield during second year. No significant difference in the panicle number per unit aren, numberof filled spike- lets, panicle weight and 1000 grain weight due to sources and time of application of N during first year.
