Response of Soybean (Glycine max L.) to Arbuscular Mycorrhizal Fungi (AMF) applied with organic liquid fertilizer

This study aimed to obtain the best dose of Arbuscular Mycorrhizal Fungi (AMF) and the best concentration of liquid organic fertilizer made from overripe fruits for the growth and production of soybean plants. The trial was conducted at the Experimental Farm, Faculty of Agriculture, Universitas Hasanuddin, Makassar, South Sulawesi, from June to August 2017. The research was carried out in the form of a 2-factor factorial experiment using a Randomized Blocked Design (RBD) as environmental design. The first factor was the AMF dose with three levels, namely control (0 g polybag(-1)), 10 g polybag(-1), and 15 g polybag(-1). The second factor was the concentration of liquid organic fertilizer with three levels, namely control (0 ml 15 ml L-1, and 20 ml L-1. The experimental results show that the application of the mycorrhizal fungi on the soybean plants did not have a significant effect on several growth and production components, but it has a very significant effect on the number of branches parameter. Application of AMF of 10 g polybag(-1) gave the best result on parameters of flowering age, number of pods, dry seed production and weight of 100 seeds. The concentration of liquid fertilizer of 15 ml L-1 resulted in the best result on parameters of plant height, number of leaves, and flowering age.
