Abstract:
This study aims at elucidating the combined effects of Vesicular Arbuscular Mycorrhiza with different organic and inorganic treatments in increasing the phosphorus content of alkaline soil. A pot experiment was conducted to study the interactive effect of VAM on soil pH, soil available P, phosphatase activity and inorganic P fractions. The experiment was carried out in a factorial completely randomized block design (FCRD) with four replications and five different treatment combinations. Control (no P), P alone, P + FYM, P + EFYM, P + Humic Acid. The five treatments were tried with and without VAM. The results showed that the treatment in which phosphorus was applied along with FYM and VAM showed greater soil available P (26.12 kg ha-1) and alkaline phosphatase activity (69.80µg p-nitro phenol released g-1 soil hr-1) at the harvest stage of the crop. The significant difference in soil pH was also observed under the application of FYM along with VAM. The phosphorus fixed as inorganic fractions such as Saloid P, Reductant soluble P, Ca P, Fe P and Al P was also significantly reduced by VAM application along with FYM.
