Abstract:
Two field experiments were conducted at the Rice Research Station,
Pattambi on seed bed manuring using IRS and Jaya as test varieties.
The first experiment (1969—70, 1970—71) aimed to study whether nitrogen
application in the main field (0, 40, 80," 120 kg/ha) could be reduced by
phosphate manuring (0, 30, 60, 90 kg/ha) of the seed bed. The results showed
that response to nitrogen was independent of the dose of phosphours applied
in the seed bed.
The effect of nitrogen (0, 40, 80 kg/ha) phosphorus (0, 25, 50 kg/ha)
and potash (0, 25, 50 kg/ha) individually and in factorial combinations, on the
productivity of rice seedlings was investigated in tde second experiment (1970-
71, 1971—72). The results conclusivly proved that applied nutrients had no
significant influence on grain yield.
