Effect of Giving Arbuscular Mycorrhizal Fungi (AMF) and Bioactivator Dosage of Trichoderma spp. on the Growth and Products of Soybeans (Glycine max L. Merr.)

Summary/Abstract: Several factors become an obstacle to increasing soy production and achieving quality standards for soybean yields, including limited water, especially in rain-fed areas, that determine the success of soybean cultivation. The use of Trichoderma spp. Bioactivators and AMF can be a solution for adding organic material to soy cultivation. This study aims to investigate the effect of AMF and the bioactivator Trichoderma spp. on growth, yield in soybeans (Glycine max L. Merr,). The design used is a two-factor split-plot design. Because the main plot was AMF, which consisted of without and with AMF (15 g/plant). The subplot is the dosage of bioactivators (tablet and liquid form with legundi leaves fermented by Trichoderma spp.), Consisting of seven levels without bioactivators, 2.5 g tablets with bioactivators, 5.0 g tablets with bioactivators, and 7.5 bioactivators. g tablets, containing 2.5 ml liquid bioactivator, 5.0 ml liquid bioactivator, and 7.5 ml liquid bioactivator. The treatment was a combination of FMA factor and bioactivator dose, each of which was repeated three times so that there were 42 experimental units. The results showed that the administration of AMF at a dose of 15 g/plant showed better growth of the soybean plant and yielded a yield of 29.27% or 1.13 tons/ha. While the administration of Trichoderma spp bioactivator at a dose of 5.0 ml can increase the growth of soy plants and give higher yields of dry soybean seeds, namely 31.54% or 1.28 tons/ha.
