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.

Highlights

In West Nusa Tenggara, the development of dryland agriculture is a superior and a mainstay of the future as most of the NTB area, namely 84 % (1.8 million hectares), is dry land that has the potential has to be developed into productive agricultural land for various raw materials. food crops, especially soybeans [17].Soybean plants have been shown to adapt well to the dry, the yields obtained are still lower than those in wetlands [3, 2]
The combination of different components of biological technology that provides a synergistic effect on plants and soil systems, such as the use of bioactivators and the use of Arbuscular Mycorrhizal Fungi (AMF) and superior soybean varieties resistant to soil pathogens, is an organic agricultural component that can be applied to soybean crops [25]
The plot child is a dosage of bioactivators which consists of seven levels, namely without bio-activator, with bio-activator 2.5 g tablet, with bio-activator 5.0 g tablet, with bio-activator 7.5 g tablets, with 2.5 ml liquid bio-activator, 5.0 ml liquid bio-activator, and 7.5 ml liquid bioactivator
