Abstract

One alternative to soybean cultivar production was utilization of Rhizobium and AMF as biofertilizers. The experiment was aimed to get a Rhizobium and AMF combination which capable to increase growth and yield of soybean in Ultisols of Bengkulu.This experiment was arranged in split block design and consisted of two factors. The first factor was soybean genotype, Pangrango, Ceneng, DSI (Malabar x Kipas Putih).The second factor was inoculant of Rhizobium and AMF namely: G. manihotis + Rhizobium of KLR 5.3 strain, G. manihotis + Rhizobium of TER 2.2 strain, Gigaspora margarita + Rhizobium of KLR 5.3 strain, Gigaspora margarita + Rhizobium of TER 2.2 strain, fertilizer NPK at recommended dosage without inoculants respectively. All replication received 1 ton ha-1 of farmyard manure, biofertilizer treated plot received 54.3 kg ha-1 Urea, 55.5 kg ha-1 SP36, and 185.2 kg ha-1 KCl. Chemical fertilizer application was 217.4 kg ha-1 Urea, 222.2 kg ha-1 SP36, and 185 kg ha-1 KCl. The results of the experiment showed that biofertilizer combination that ca be recommended for use is ultisols are Glomus and Rhizobium of Kandang Limun origin (R1) and Talang Empat origin (R2) and Gigaspora only with Rhizobium of Talang Empat origin (R2)
