Production of soybean in the application of Rhizobium spp. and Actinomycetes spp.

Abstract

This study aims at determining the effect of bacteria Rhizobium spp. and Actinomycetes spp. on the production of soybean crops. The research was conducted at the Laboratory of the Department of Agriculture Cultivation of Hasanuddin University and in Tarowang Village, South Galesong District, Takalar District, South Sulawesi, from July to November 2017. The research was conducted in the form of 2 factor factorial experiment arranged in Split Plot Design (SPT). The first factor is the bacteria Rhizobium spp. consists of no Rhizobium spp. and Rhizobium spp. with a density of 1x106 CFU mL-1, and the second factor is Actinomycetes spp., consists of no Actinomycetes spp., Actinomycetes spp. with density of 1x103 CFU mL-1 and 1x106 CFU mL-1. The results showed that interactions of Rhizobium spp. with a density of 1x106 CFU mL-1 and Actinomycetes spp. with a density of 1x103 CFU mL-1 significantly affected the number of root nodules per plant and the number of effective root nodules, but Interactions of Rhizobium spp. with a density of 1x106 CFU mL-1 and Actinomycetes spp. with a density of 1x106 CFU mL-1 no significant increased weight of 100 seeds.. Rhizobium spp. with a density of 1x106 CFU mL-1 significantly increased the number of pods per plant. Actinomycetes spp. with a density of 1x106 CFU mL-1 significantly increased seed weight per plot and seed weight per hectare.
