Abstract:
A field experiment was conducted at the Rice Research Station, Moncompu
to assess whether rice crop can be raised without continuous application of
phosphorus and potash in the clay loam soils of Kuttanad. The variety used
wasTriveni. Results revealed that skipping of potash during the alternate seasons
is not affecting the yield, end hence csn be adopted for economising ihe expenditure.
Skipping of phosphorus is having depressing effect on yieid. Application
of nitrogen alone without phosphorus and potash has shown significant
reduction in yield, and the crop exhibited typical symptoms of phosphate
deficiency.
