PEMBERIAN FUNGI MIKORIZA ARBUSKULA DAN BIOCHAR TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KEDELAI (Glycine max (L.) Merril) PADA TANAH ULTISOL

Soybean is one of the main needs and sources vegetable protein for Indonesian. National soybean continue to increase in line with population, but production has not been able meet national needs. Therefore, efforts need be made by utilizing marginal land using arbuscular mycorrhizal fungi biochar. The aim this study was determine effect single factors (AMF), biochar interaction these two on growth yield Ultisol soil. This research conducted from December until March 2019. used 3 x factorial completely randomized design three replications. first factor AMF dosage consist levels : M0 (0 g per plant), M1 (15 M2 (30 plant) second type B0 (without biochar), B1 (biochar rice husk), B2 coconut shell). observation data that obtained were analyzed statistically analysis variance (ANOVA). results continued Duncan's multiple range test at level 5%. showed treatment improved all parameters can improve parameters. between did soybean.
