Abstract
Incubation study was carried out in the Laboratory of Department of Agricultural Chemistry and Soil Science, C.P. College of Agriculture, S.D. Agricultural University, Sardarkrushinagar. Treatments comprising of three levels of moisture regimes, three levels of P of two P carriers, two levels of FYM and five incubation intervals were evaluated under completely randomized design (with factorial concept) with three replications. Available P2O5 content in soil was increased significantly with application of FYM @ 10 t ha-1 with 2.68 mg P/ 100 g soil and maintenance of moisture at 25% available water capacity was found significantly higher as compared to without FYM. Available P2O5 increased up to 3rd DAI then decreased with respect to phosphorus availability in loamy sand. Under the different forms of phosphorus, maintenance of moisture at 100% available water capacity, FYM @ 10 t ha-1 and P 2.68 mg P/ 100 g soil increased the inorganic-P and total-P up to 14th DAI.
