Respon Pertumbuhan dan Produksi Tanaman Kedelai Terhadap Pemberian Biochar Cangkang Biji Kemiri dan Pupuk Organik Cair dari Kulit Pisang

Abstract

This study aims to determine the response of growth and production of soybean crops to the provision of biochar shell of candlenut and liquid organic fertilizer (POC) from banana peel. The design used was Factorial Random consisting of 2 treatment factors: (1) Biochar Kemiri Biji Shell (B) consist of 3 levels, B0 = without biochar, B1 = dose 5 ton / ha, B2 = dose 10 ton / ha. (2) POC of Banana peel (P) consists of 4 levels, P0 = without POC, P1 = POC concentration 1%, P2 = POC 2% concentration, P3 = 3% concentration, the results of this study indicate that the seed shell biochar hazelnut has a very significant effect on plant height, leaf area, root volume, and significant effect on the number of pods / samples. The best treatment is the biochar shell of candlenut seeds as much as 5 tons / ha. The provision of POC from banana peel was very significant to plant height, and had significant effect on leaf number, leaf area, branch number, root volume, and number of pod / sample. The best treatment is POC from banana peel at 1% concentration. Combination of biochar of pecan seed shell and POC from banana peel was very significant on root volume, weight of pod production / sample, and significant effect on number of pod / sample, number of pod / plot, biomass / sample. the best treatment is the biochar shell candlenut dose 5 ton / ha and POC from banana skin concentration of 1%.
