PENGARUH 2 VARIETAS DAN BEBERAPA ISOLAT RHIZOBACTER TERHADAP PRODUKTIVITAS TANAMAN KEDELAI (Glycine max (L.) merril)

Soybeans are a great source of calcium, iron, zinc, phosphorus, magnesium, thiamine, riboflavin, niacin and folic acid. Soybeans contain large amounts of essential amino acids for humans, and so are a good source of protein and vegetable oils. Dried soybeans contain 34% protein, 19% oil, 34% carbohydrates (17% dietary fiber), 5% minerals and several other components including vitamins, isoflavones. Soybean plants need a balance between temperature and humidity which is influenced by rainfall. In general, soybean plants require high air temperatures and low rainfall (humidity). If the air temperature is low and the rainfall (humidity) is too high, it will result in a decrease in the quality of the soybeans produced. However, domestic soybeans continue to experience increasing demand, until Indonesia imports soybeans to meet domestic needs. Based on these problems, a solution is needed, namely by giving rhizobacteria to increase soybean productivity. The purpose of this study was to determine the effect of various bacterial isolates on the productivity of soybeans (Glycine max (L.) merril) Dega1 and Anjasmara varieties and also to determine whether there was an interaction between the administration of various rhizobacterial isolates and soybean (Glycine max (L.) merril). ) Dega1 and Anjasmoro varieties. This study was conducted using a factorial RAK Split Plot experimental design with two factors and three repetitions. The first factor is the variety, there are Dega1 and Anjasmoro varieties, while the second factor is the treatment, namely zpt and 3 rhizobacter with each treatment of 5 soybean plant samples. The results of this study showed that soybean plants treated with rhizobacteria increased the productivity of the two soybean varieties. The treated soybean plants had more leaves than the control. Meanwhile, the height of soybean plants in the two varieties in the control had a lower height compared to the height of the soybean plants that were given the treatment. With the large number of leaves on soybean plants will also add branches to soybean plants, so that more flowers will appear in the armpits of the leaf branches. This will increase the number of pods that grow on the soybean plant
