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.
