【 摘 要 】
The availability of P in Andisol is low because phosphate is absorbed by allophane, Al and Fe minerals on the colloidal surface so that it is not available for plants. This research aim was to determine the effect of phosphate solubilizing microbes and chicken manure in increasing P availability and the growth of green beans (Phaseolus radiatus L.) plants on Andisol. This research was carried out at the Greenhouse and Laboratory of Soil Biology, Faculty of Agriculture, Universitas Sumatera Utara, Medan. This research used a randomized block design with 2 treatment factors and 3 replications. The first factor is phosphate solubilizing microbes (PSM), namely: (M0) without application, (M1) 5 gr mycorrhiza, (M2) 5 gr Burkholderia cepacia bacteria, (M3) 5 gr Talaromyces pinophilus fungi. The second factor is the dose of chicken manure, namely: (A0) 0 gr, (A1) 80 g, (A2) 120 g and (A3) 160 g. The results showed that the administration of phosphate solubilizing microbes and chicken manure could increase P-available by 10.78-50.82%, total leaf area by 8.63-65.18%, plant dry weight by 2.46-58.25% and plants P content by 24-99%, the best treatment was the interaction of T. pinophilus fungi with a dose of 160 gr / plant chicken manure.【 预 览 】
