Abstract

Abstract Rhizobium is one of the important microorganisms in free nitrogen fixation. The study aims to determine the use of Rhizobium spp as substitute for chemical fertilizer Nitrogen on soybean cultivation. The experiment design was a randomized complete block with four replications, using Rhizobium isolate in granule and powder media with spraying volume 600cc/kg granules and 400cc/kg of powder. The treatment dosage consisted of 3 g; 4 g; 5g and 6 g/plant, while the control was Phonska fertilizer 1,5 g/plant. The results showed that the use of rhizobium granules and powder as much as 4 g / plant was not significantly different in the formation of root nodules compared with control; the use of Rhizobium in granules and powder 6 g/plant for the number of pods did not show a significant difference; the use of 4 g - 6 g/plant for seed weights compared to controls also did not show a significant difference. The use of Rhizobium isolate 400cc/kg granules and 600cc/kg of powder can be used to replace the use of Phonska in soybean cultivation.
