Abstract

The research was carried out in the experimental field of the Faculty of Agriculture, Asahan University. Asahan Regency, North Sumatra. 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 rhizobium biofertilizer with 3 levels, namely R0 = 0 g Rhizobium biofertilizer per 250 g soybean seed (control), R1 = 1.5 g Rhizobium biofertilizer per 250 g soybean seed, R2 = 3.0 g fertilizer Rhizobium Bio per 250 g soybean seed and    R3 = 4.5 g Rhizobium Biofertilizer per 250 g soybean seed. The second factor is the Treatment of Tillage System (O) with 3 levels, namely O0 = No tillage (control), O1 = Minimal tillage (hoeed without turning), O2 = Perfect tillage (hoeed and turned). The results showed that the treatment of Rhizobium biofertilizer on plant height 3 weeks after transplanting was best at a dose of 4.5 g of Rhizobium biological fertilizer (R3) which was 37.66 cm, the number of branches aged 3 weeks after transplanting was best at a dose of 4.5 g rhizobium biofertilizer (R3) which is  7.14 branches, the number of pods contains per plant the best sample is at a dose of 4.5 g rhizobium biofertilizer (R3) is 218.06 pieces, the best production per sample is at a dose of 4.5 g biofertilizer rhizobium (R3) is 20.12 g, the best production per plot at a dose of 4.5 g of rhizobium biological fertilizer (R3) is  0.32 kg and the best number of root nodules at a dose of 4.5 g of rhizobium biological fertilizer (R3) is 15 ,53 pieces. Tillage system (O) treatment hada signi ficant effect on plant height at 3 weeks after transplanting, number of branches aged 1 and 3 weeks after transplanting, number of pods filled per plant sample, production per sample, and production per plot. The best plant height at   3 weeks after transplanting with perfect tillage treatment (O2) was 37.42 cm, the number of branches aged 3 weeks after transplanting was best with perfect tillage treatment (O2) was 7.25 branches, the number of pods contained per the best sample plants with perfect tillage treatment (O2) was 203.30 pieces, the best production per sample with perfect tillage treatment (O2) was 17.26 g and the best production per plot with perfect tillage treatment (O2) was 0, 27 kg. The interaction of rhizobium biofertilizer and tillage system did not affect all parameters of black soybean plant.
