Effect of different levels of phosphorus and phosphorus solubilizers on phosphorus fractions in soil at different stages of paddy

Abstract

In order to know the effect of P levels and P solubilizers on P fractions in soil at different growth stages of Paddy a field experiment was conducted at Agricultural and Horticultural Research station Bavikere, during kharif seasion in 2017-18. The levels of phosphorus at 0, 50, 75 and 100 % P2O5 as per ha-1 with and without P solubilizer seedling treatment were tried in a randomized complete block design (RCBD) with twelve treatments and three replication. At different growth stages higher valves of Saloid – P and Ca – P and available P status in soil were recorded in treatment received recommended NPK with PSF seedling treatment. Higher values of Al-P, Fe – P, red – P, occl – P, organic – P and total – P fractions were recorded in treatments recieved only P levels without P solubilizers seedling treatment compared to the application of P levels with P solubilizers seedling treatment.
