Abstract

The natural resources of the coastal area in Indonesia have the potential to be developed as an agricultural land with the support of both cultivation technology and land processing which one of them is by using Rhizobium japonicum bacteria to meet the need of nitrogen in soybean plants. This study aims to determine the characteristics of nitrogen fixation in various soybean cultivar planted in the coastal area. The research was conducted in Mancingan, Parangtritis, Kretek, Bantul, DIY. The study was done using Completely Randomized Design which consisted of two factors and repeated three times. Factor I was Rhizobium japonicum inoculation (with inoculation and without inoculation); factor II was 10 various cultivar of soybean (Grobogan, Burangrang, Argomulyo, Anjasmara, Dena 1, Gema, Kaba, Wilis, Sinabung, Gepak Kuning). The results showed that the inoculation of Rhizobium japonicum in soybean cultivars in coastal area can increase the number of root nodule, dry weight of root nodule, dry seed weight per plant, and harvest index. Burangrang cultivar planted in coastal area is the most responsive to Rhizobium japonicum inoculation among other soybean cultivars tested
