Effect of applied P on soli fractions in green manure- rice cropping system

Abstract

                                Application of recommended level of P at 60 kg P2O3ha-1 maintained higher available soil P (22.06 kg ha). The amount of inorganic P varied significantly and the distribution of added P into different fractions was in the order of Ca-P> Fe-P> AL-P. Application of 50% P2O3 to rice recorded significantly higher P uptake.

Key words : Available P. Inorganic P and P uptake
