The Effect of Organic Matter on The Soil Innoculated Mycorrhizal on The Persentage of Root Infection and Growth of Mung Bean Plants

Abstract

This study was conducted to analyze the effect of organic matter application on mycorrhizal inoculated soil on the percentage of AMF infection and the availability of phosphorus nutrients for the growth of mung beans. The research was conducted at the Green House, Universitas Muslim Indonesia, and in the Microbiology laboratory of the Environmental and Forestry Research Institute, Makassar, which was carried out from May to August 2021. This research was conducted in an experimental form based on a completely randomized design consisting of four treatments with three replications. The treatments tested were planting media, namely sand + soil (without organic matter), sand + soil + husk, sand + soil + husk charcoal, and sand + soil + husk + husk charcoal. Parameters observed in this study were total soil P nutrient content, available P content, percentage of mycorrhizal infection, plant height, number of leaves, root length, and root volume. The results showed that the percentage of root infection with the application of organic husk material obtained the percentage of root infection up to 83.67%. Plant growth and nutrient levels of total P and available P were higher with the application of husk organic matter and husk charcoal.
