Pengujian Pupuk Organik Cair Urine Domba dengan Biochar Cangkang Biji Kemiri pada Tanaman Kedelai (Glycine Max L)

Abstract

This study aims to determine how the results of organic fertilizer liquid urine sheep combined with biochar shell of candlenut seeds on the growth and production of soybean crops. This research was done by using Factorial Random Block Design (RAK) Factorial consisting of 2 factors of treatment that is: first factor Biochar candlenut Seed Shell consists of 4 levels that is B0 = Positive Control (No Biochar), B1 = Negative Control (NPK fertilizer with standard dose ie 300 kg/hec), B2 = Biochar 5 tons / ha (0.5 kg/m2), B3 = Biochar 10 tons / hec (1 kg / m2). The second factor of Sheep Liquid Organic Fertilizer consist of 4 Treatment Levels: U0 = No Organic Fertilizer Liquid Sheep Urine (0%), U1 = Organic Fertilizer Liquid Urine Sheep 0.75% (7.5 ml/l), U2 = Organic Fertilizer Liquid Sheep Urine 1.5% (15 ml / l), U3 = Organic Fertilizer Liquid Urine Lamb 2.25% (22.5 ml/l) The results of this study indicate that Giving biochar shell of candlenut seeds very significant effect on height of plant, stem diameter, and significant effect on the number of leaves, seed production for bed and plant biomass. Best treatment is the biochar shell of seeds of candlenuts as much as 5 tons / hec. Giving of Organic Fertilizer Liquid Urine Sheep have a very significant effect on plant height and significant effect on seed production for sample, weight of 100 seeds for sample, seed production for plot, seed production for hectare, and plant biomass for sample The best treatment is giving of Organic Liquid Fertilizer Urine Lamb 2.25%.
