Abstract

Post tin mining land in Bangka Island can be utilized as agricultural land with the application of organic fertilizer and Rhizobium. Organic fertilizer and Rhizobiumare the right combination to provide a good planting environment for edamame soybean. The purpose of this study was to study the effects of organic fertilizer and Rhizobium the growth and yield of edamame soybean in post tin mining land. This research was conducted in a post-tin mining land, Bangka, from January to May 2020. This research used a split-plot randomized complete block design. The main plot was an application of Rhizobium (legin) consisting of without Rhizobium (R0) and Rhizobium (R1). The subplot was the application of organic fertilizer consisting of empty palm fruit bunch (P1), husk (P2), and commercial compost (P3). The results showed that commercial compost gave the best effect on plant height, the number of leaves, chlorophyll content, weight of 100 seeds, number and weight of pods per plant, number and volume of roots. Rhizobium gave the best effect on the numbers of roots, root volume, and percentage of effective root nodules. The combination of husk and Rhizobium legin gave the best effect on the flowering day of edamame soybean in post tin mining land.
