Studies on the fractional application of nitrogen on the yield of rice

Abstract

The effect of fractional application of nitrogen on the grain yield of two high yielding rice varieties Jaya and Annapurna was studied for six consecutive seasons during 1972-73 to 1974-75 in the Rice Research Station, Mannuthy. Significant results were obtained in two first crop seasons and the treatments receiving 50 kg N as basal and another quantity of 50 kg N in two equal splits given either at booting and heading or at panicle initiation and booting gave maximum grain yield.
