ABSTRACT
This study aims to determine the effect of various biochar materials and doses of chicken manure fertilizer on soil chemical properties, growth and yield of soybean. The research method used a 2 factorial Randomised Group Design. The first factor was the treatment of various biochar materials consisting of 4 levels, namely: B0 without treatment, B1 (corn cob biochar 1.5 kg/m2, B2 (jengkol bark biochar 1.5 kg/m2), B3 (rice husk biochar 1.5 kg/m2). Factor II was chicken manure (P) consisting of P0 (0 kg/m2), P1 (0.5 kg/m2), P2 (1 kg/m2 and P3 (1.5 kg/m2). The application of various biochar materials and chicken cohe fertilizer gave a real response to soil pH, organic C, total N, available P and K available. The results showed that the application of biochar to the growth and yield of soybean plants gave a significant effect on the parameters of stem diameter, number of productive branches, number of pods, dry weight of seeds/m2, seed production/ha. The application of jengkol skin biochar gave the highest effect on stem diameter (1.750 cm), number of productive branches (5.06 branches), number of pods (181.60 pods), dry weight of seeds/m2 (442.98 grams). The application of chicken manure fertilizer on the growth and yield of soybean plants gives a significant effect on stem diameter, number of productive branches, number of pods, dry weight of seeds/plot. The dose of chicken manure fertilizer 1.5 kg/m2 showed the highest effect on stem diameter (1.79 cm), number of productive branches (5.19 branches), number of pods (184.22 pods), dry weight of seeds/m2 (398.50 g). The interaction of biochar and chicken manure fertilizer did not give significant effect on all treatments.
