Abstract

Field experiments conducted at the Agricultural Research Station, Bhavanisagar, during 1981-1987 to determine the P and Krequirement of rice in "rice-rice" system revealed that addition of P2O5 and K20 up to 50 kg/ha continuously for nine seasons failed to influence the grain yield. Continuous addition of P20s resulted in considerable build up of available P2Os content of soils. Soil K status was not altered by the Continuous application of varying rates of potassium.
