Daftar Isi:
- Indonesian Soybean production in 2009 amount was to 974,512 tons. Meanwhile, the domestic soybean demand was 2,000,000 tons. Therefore, the Indonesia must import 1,000,000 tons more to meet their needs. This is a direct impact on domestic food needs. Utilization of crop land under forest / tree planting to increase the area of soybean land. This is to overcome the lack of agricultural land are still available in Indonesia. Maximizing the role of Bradyrhizobium japonicum to tie up N (nitrogen) elements of nature is one effort to streamline the process fertilizer on soybean plants. Thus expected to increase growth and yield of soybean in the country. The purpose of this study was to study the relationship Bradyrhizobium japonicum isolate of biological nitrogen fixation, growth and yield of soybean under Paraserianthes falcataria. The study was conducted in Malang, East Java and Biotechnology Laboratory University of Muhammadiyah Malang, from May until August 2010. The experimental used simple Randomized Block Design, with 10 treatment, each was repeated 3 times. The results of this study indicate that Bradyrhizobium japonicum isolates in soybean cultivation under Paraserianthes falcataria, increase the nodule number and nodule dry weight at 60 days after sewing. Bradyrhizobium japonicum can also contribute to soil N 72.62% and plants N with a range of 4.6% -13.25%. However, Bradyrhizobium japonicum has not been able to increase plant growth (plant height, leaf number, leaf area), biomass (roots, stems and leaves) and yield (pod number, empty pods number and pod dry weight)
