Abstract

Sorghum grown on loam soil (pH 7.4) was given 40-160 kg N, 0-120 kg P2O5 and 0-60 kg K2O/ha in 17 combinations and correlations between amounts of available P2O5 in soil at different depths extracted by using 4 extractants and grain yields were determined. The amount of available P2O5 extracted by using the Olsen extractant was the highest. There were positive significant correlations between yield and the amount of P2O5 extracted with this method from 0-10 and 10-20 cm depths. Application of 160 kg N + 120 kg P2O5 + 60 kg K2O/ha gave the highest yields
