Nitrogen Management to Improve the Nutrient Uptake, Yield and Quality Parameters of Scented Rice under Aerobic Culture

In the present study, the research results concluded that yield attributes of scented rice under aerobic culture responded up to 150 kg/ha nitrogen with four equal splits of nitrogen at 1⁄4 basal + 1⁄4 at active tillering + 1⁄4 at panicle initiation and 1⁄4 at heading. Grain and straw yields obtained higher values with highest level of nitrogen i.e. 175 kg/ha comparable with 150 kg/ha. Grain quality parameters milling percent, head rice recovery, kernel length, breadth, amylose content and protein content of rice registered significantly highest values with 150 kg N ha. Spilt application of nitrogen at 1⁄4 basal + 1⁄4 at active tillering + 1⁄4 at panicle initiation and 1⁄4 at heading was the most suitable stages for split application of nitrogen, which record significantly higher values of all quality parameters except amylose and protein content of grain. Nutrient uptake of N, P2O5 and K2O was influenced only by quantity of nitrogen applied and recorded higher with 175 kg/ha but not influenced by time of application of nitrogen except N uptake.
