Description 1267-1275
In this work, two phosphate solubilizing fungi viz., Aspergillus tubingensis S33 and A. niger S36 were studied under different physiochemical and nutritional parameters in the lab, and in vitro under soil-plant experiments at two very distinct agro-climatic conditions viz., Banasthali, Tonk (Rajasthan), and Dwarahat, Almora (Uttarakhand), India. Phosphate-solubilizing capability was checked with different carbon and nitrogen sources. Maltose, glucose, and fructose were optimal carbon source in A. tubingensis S33 while fructose in the case of A. awamori S33. Amongst nitrogen sources, S33 showed maximum phosphate solubilization with ammonium sulfate while, S36 with ammonium sulfate and sodium nitrate. Ammonium was more stimulating than nitrate as the chief nitrogen source. In vivo experiments revealed that solubilization was noticeable at all the temperatures, but optimal temperature was 25ā€“35ā„ƒ. The optimal initial pH for Tricalcium Phosphate (TCP) solubilization was 8.0. The ideal concentration of TCP for solubilization was 7.5 gāˆ™lāˆ’1. The application of both strains in two different geographical sites exhibited a significant (p
