| Various organic materials like humic acid (HA) can be used to enhance P availability from rock phosphate (RP). To investigate the effect of RP augmented with two levels of HA on the productivity of wheat and P uptake, a field trial was conducted. Treatments used were Control (No RP, No HA), rock phosphate alone (RP), RP mixed with HA @ 5 Kg ha ‒1 (RP+HA-5) and RP mixed with HA @ 10 Kg ha ‒1 (RP+HA-10) and were replicated 3 times randomly in Complete Block Design. Addition of RP significantly increased soil P 2 O 5 content, P uptake, total dry matter, grains, and straw yield of wheat over control. Whereas application of RP with increasing amount of HA augmentation further increase these soil and crop parameters over RP alone. The increase in soil P 2 O 5 content, P uptake, grains, total dry matter, and straw yield of wheat was in the order RP+HA-10 > RP+HA-5 > RP > Control. This study conclude that RP can be used as P fertilizer efficiently when HA is mixed with it in order to increase P availability, nutrient uptake and wheat productivity.
