【 摘 要 】

Andisol is a soil formed from volcanic ash and has a problem with low P availability in the soil. The purpose of this research was to determine the effect of phosphate solubilizing fungi, various sources of P fertilizer and phosphate solubilizing fungi interactions to increase P availability and soybean plant growth in Andisol soil. The research was carried out at the Faculty of Agriculture Greenhouse and USU Soil Biology Laboratory, Medan 2018. This research used Factorial Randomized Block Design (RBD) with 2 Treatment Factors and 3 replications. The first factor is phosphate solubilizing fungi, namely; M0 (without application of PSF), M1 (5g Talaromyces pinophilus), M2 (5g Aspergilus terreus), M3 (2.5g Talaromyces pinophilus + 2,5g Aspergilus terreus). The second factor is various sources of P fertilizer, namely; P0 (Without application P), P1 (0.78g TSP), P2 (1g SP36) and P3 (1.3g RP). The research results showed that the application of phosphate solubilizing fungi and P fertilizer could increase the availability of P as much as 1.4-15.4%, plant dry weight as much as 21.6-42% and plant P content as much as 1.3-8.9%. The best treatment was the interaction of Talaromyces pinophilus with SP36.
