The effect of bokashi fertilizer from agricultural waste contain Trichoderma to improve soybean production, growth, and resistance against plant diseases

Abstract

This study focus on the development agent of biological control based on technologies used Trichoderma mix with bokashi fertilizer from agricultural waste. This study arranged in a randomized block design (RBD) in a factorial pattern, factor I is a type of decomposer microorganism that consisted of three treatments (M1: EM4 decomposer, M2: Trichoderma decomposer, M3: EM4 decomposer and Trichoderma), and factor II is the type of agricultural waste, consisted of four treatments (L1: soybean plant waste, L2: rice crop waste, L3: corn plant waste, and L4: a mixture of various agricultural waste) so there were 12 combinations of treatments with three repetitions. The observations data have been analyzed used variance and continued with the Duncan multiple distance test (DMRT) at the 95% confidence level. The result showed the application of bokashi from agricultural waste using EM4 and Trichoderma can increase plant growth, plant production, and resistance from plant pathogenic both independently and interactively, especially for Cucumber Mozaic Virus (CMV) and Soybean Mozaic Virus (SMV). In the other hand, the experimental study confirms that the Legume agricultural waste (L1), EM4 decomposers, and Trichoderma (M3) are the best combination to increase the growth, production, and durability of soybean crops either by main-treatment or interaction treatment compared to other treatments.
