Peranan Rhizobium dalam Meningkatkan Ketersediaan Nitrogen bagi Tanaman Kedelai
Oleh: Novriani
Abstract
Supplies nutrients nitrogen in soybean crop is high enough, to meet the nitrogen needs during growth, it can be done given rhizobium. Rhizobium bacteria that can be symbiotic with the soybean crop is rhizobium japanicum. This bacterium is able to fixate nitrogen at 100-300 kg/ha, so it can meet the needs of 80% nitrogen for soybean. Besides able to fixate nitrogen rhizobium can also produce hormones such as IAA and giberalin grow. Rhizobium...
