Abstract

This research was carried out at the Experimental Field of the Faculty of Agriculture, Asahan University (UNA) Kisaran, Asahan Regency, North Sumatra Province with an altitude of ± 17 m above sea level. This study was arranged based on a factorial randomized block design (RAK) with 2 treatment factors and 3 replications. The first factor is the treatment of super compost (K) with 3 levels, namely K0 = 0 tons/ha (control), K1 = 5 tons/ha (8.5 kg/plot), K2 = 10 tons/ha (17 kg/plot). The second factor is the concentration of POC JST (J) with 4 levels, namely J0 = 0 ml/liter water/plot, J1 = 15 ml/liter water/plot (1.5%), J2 = 30 ml/liter water/plot (3 %), J3 = 45 ml/liter of water/plot (4.5%). The results showed that the treatment of super compost fertilizer on plant height 3 weeks after transplanting was best at a dose of 17 kg of super compost fertilizer (K2), which was 30.73 cm, the number of branches aged 3 weeks after transplanting was best at a dose of 17 kg of super compost ( K2) is 8.31 branches, the number of pods containing per plant the best sample at a dose of 17 kg of super compost fertilizer (K2) is 50.53 pieces, the best pod production per sample at a dose of 17 kg of super compost (K2) is 30.72 g, the best production per plot at a dose of super compost fertilizer (K2) is 0.30 kg. The concentration of POC JST (J) had a significant effect on plant height at 3 weeks after transplanting, number of branches at 3 weeks after transplanting, number of pods filled per sample plant, pod production per sample, and pod production per plot. The best plant height was 3 weeks after transplanting with POC JST treatment with a concentration of 4.5% (J3), which was 29.23 cm, the number of branches aged 3 weeks after transplanting was best with POC JST treatment with a concentration of 4.5% (J3), which was 7, 25 branches, the number of pods containing per plant the best sample with POC JST concentration of 4.5% (J3) ie 48.76 pieces, the best pod production per sample with POC JST treatment with a concentration of 4.5% (J3) that is 29.44 g and the best production per plot with POC JST treatment with a concentration of 4.5% (J3), which is 0.31 kg. The interaction of super compost fertilizer and POC JST concentration did not affect all plant parameters of soybean varieties edamame.
