UJI KEMAMPUAN SPORA CENDAWAN MIKORIZA ARBUSKULA (CMA) LOKAL BALI PADA PERTUMBUHAN TANAMAN KEDELAI (Glycine max L.)

Necessity of soybean in Indonesia increase every year along with population growth. The goverment need to import the soybeans from abroad. Soybean in Indonesia are generally planted in ricefield and upland (dryland) which have potential of deficiency water. Water deficiency can caused the reduction of soybean production. Therefore some alternatives are needed to increase the yield of soybean productivity, one of them is applying arbuscular mycorrhizal fungi (AMF). The aim of this research was to know the dosage of isolates AMF to increase the growth of soybean. The experiments conducted over 2 months at Agriculture Faculty’s Greenhouse, Udayana University. The research use Completely Randomized Design which consists of 5 treatments, which are : without inoculation/negative control (M0), 50 spores AMF (M1), 100 spores AMF (M2), 150 spores AMF (M3), and ZA/positive control (M4). The results showed that, the inoculation of spores AMF Bali indigenus were significantly different (P0,05) based on analysis of variance (ANOVA) level 5%. Doses 50 spores AMF (M1) is the dose of inoculants has been able to increase number of leaves, leaf length, root fresh weight, and percentage of root colonization.
