Abstract

Field experiments were conducted at the Agricultural Research Station, Bhavanisagar during kharif seasons of 1994 and 1995 on transplanted rice to study the effect of doses and timing of N application. Increasing rate of N application upto 200 kg N/ha significantly increased the grain" yield mainly dur to improvement in yield attributes like productive tillers and filled grains per panicle. N applied in 5 splits at 7 DAT, active tillering, panicle initiation heading and floweing stages along with Seshania rostrata incorporation produced maximum grain yield and economics.

Keywords: Transplanted rice, N fertilizer, split application, Sesbania rostratu, grain yield.
