Abstract:-

It was decided to undertake a greenhouse experiment on dry direct-seeded rice (DSR) to investigate the influence of three different amounts of fertilizer P (0, 6.5, and 13 mg kg-1 soil) administration on the changes in P fractions in soils with varied Olsen-P and texture in ten distinct soils. When comparing the administration of P fertilizer to the no-P treatment at the maximum tillering stage, the concentration of Ca-P fraction rose by a substantial amount. The increase in Ca-P fraction at flowering was statistically significant only when 13 mg P kg-1 was applied in comparison to no P administration. The values of the Fe-P and Al-P fractions were not substantially different regardless of the initial Olsen-P concentration or the amount of P applied to the sample
