An experiment consisting of a fertilizer rate of 69/23 kg N/P₂O₅ ha^-1 and seven nitrogen application times was conducted on Vertisols of Fogera plain during 2016/2007 cropping season. The N application times were 1/2 at sowing + 1/2 at tillering (control), 1/3 at sowing + 2/3 at tillering, 1/3 at 15 days after sowing + 2/3 at panicle initiation, 1/3 at 25 days after sowing + 2/3 at panicle initiation, 1/3 at sowing + 1/3 at mid tillering + 1/3 at panicle initiation, 1/3 at 15 days after sowing +1/3 at panicle initiation +1/3 at heading and 1/3 at 25 days after sowing + 1/3 at panicle initiation +1/3 at heading. RCB Design with three replications was used. The objective of the experiment was to identify the best time of N fertilizer application for maximum rice yield in Fogera plain. Results showed significant difference in grain yield in response to time of N application. The highest mean grain yield (3.5 ton/ha) was recorded when N was applied 1/3 at 25 days after sowing and 2/3 at panicle initiation. The Agronomic Nitrogen Use Efficiency was higher when 1/3 of N was applied at 25 days after sowing + 2/3 at panicle initiation. Therefore, it can be concluded that nitrogen applied 1/3 at 25 days after sowing plus 2/3 at panicle initiation is the appropriate time for rice production in Fogera plain.
