The Improvement of Yield and Quality of Soybeans in A Costal Area Using Low Input Technology Based on Biofertilizers

Yudhy Harini Bertham, Zainal Arifin, Abimanyu Dipo Nusantara

Abstract

Indonesia is an archipelagic country, having vast coastal areas which have not been utilized optimally for crop cultivation because their poor soil properties become a limiting factor for plant growth. It is, therefore, necessary to use cultivation technology, such as the use of soil microbes in order to overcome this limiting factor. The objective of this study was to determine the appropriate soil microbes for improving the quality of  soybean grains, the rhizosphere environment, and the soybean yield in a coastal area. The study was conducted in Bengkulu, Indonesia, using Randomized Complete Block Design, with a single factor, namely organic fertilizers. Six treatments were applied, namely addition of arbuscular mycorrhizal fungi(AMF), phosphate-dissolving fungi (PDF), Rhizobium (R), AMF+PDF, R+AMF, and R+PDF. The results of analyses showed that the dual inoculation of arbuscular mycorrhizal fungi and phosphate-dissolving fungi (AMF+PDF) resulted in the largest populations ofphospate-dissolving fungi and arbuscular mycorrhizal fungi, the highest percentage of arbuscular mycorrhizal fungi (AMF) infection, protein content in grain, tissue P content, grain weight and yield. The inoculation of phosphate-dissolving fungi (PDF) produced the highest fat content.
