Effect of Rhizobium Inoculation and Phosphate Fertilizer on The Growth of Soybean (Glycine max L) Grobogan Variety

Various strategic efforts to increase food production continue be made in an effort achieve self-sufficiency and security. Soybean is a national commodity support government programs with the aim of achieving self-sufficiency. The purpose this study was determine effect combination phosphate fertilizer rhizobium biofertilizer on growth soybean (Glycine max L) Grobogan variety. research conducted from June September 2022 at Ma'had Al Zaytun Agricultural Complex, Indramayu Regency. method used randomized block design pattern. There were 9 treatment combinations SP-36 inoculation. Fertilizer consists 3 levels, namely 100, 150 200 kg/ha Rhizobium 0.05, 0.10 0.15 g/planting hole. Each repeated three times so that there 27 trial plots. experimental plot 6 m2. observed data processed using analysis variance Scott-Knott test. results showed.that combination-of Phosphate fertilizer-and inoculation had-a significant all observations both plant height, number trifoliate leaves, branches, root volume.
