The response of soybean crop to organic fertilizers has not been fully understood in Indonesia. This research aims to investigate the response of new superior variety of Anjasmoro soybean to phosphorus and organic fertilizers in the dry climate ricefields. The experiment was conducted in Sesela Village, West Nusa Tenggara Province, Indonesia from August - November 2015 using a randomized 2-factor design. The first factor was phosphorus fertilizer with 4 levels: 0 kg/ha, 36 kg/ha, 72 kg/ha and 108 kg/ha. The second factor was organic fertilizer with 4 levels of fertilizer dosage: 0 ton/ha, 2.5 tons/ha, 5 tons/ha and 7.5 tons/ha. Parameter observed were plant height, number of leaves, number of nodules, number of productive branches, number of pods, number of empty pods, dry weight, weight of 100 seeds, and production. The results showed that the optimum dose of organic fertilizer was 7.5 tons/ha with the highest number of pods of 100. This was confirmed by the regression value (R2) of 0.97 which indicates that organic fertilizer affects the increase in the number of pods in a quadratic. Phosphorus fertilizer has an effect on the number of empty pods, number of productive pods, number of pods, productivity and production of soybean.
