Respon Pertumbuhan dan Produksi Tanaman Jagung (Zea mays L.) Terhadap Pemberian Biochar Kulit Durian dan Pupuk Kandang Ayam

Abstract

Low productivity (Zea mays L) due to reduced soil quality but organic fertilizer can add soil nutrients where chicken manure and biochar are used as soil enhancers for research purposes to determine the response of durian skin biochar and chicken manure to the growth and production of corn plants. The study used a randomized block design (RBD) factorial with durian skin biochar B0 = without Biochar, B1 = Biochar 4,1 tons / ha (0.5 kg / plot), B2 = Biochar 8,3 tons / ha (1 kg / plot), B3 = Biochar 12,5 tons / ha (1.5 kg / plot) and composting chicken manure K0 = Without Chicken Manure, K1 = Chicken Manure 8,3 tons / ha (1 kg / plot), K2 = 12,5 tons Chicken Manure / ha (1.5 kg / plot), K3 = Chicken Cage Fertilizer 16,6 tons / ha (2 kg / plot).The study began with the preparation of durian skin biochar and chicken manure then land preparation, application of durian skin biochar and chicken manure, planting, maintenance of maize and crop observations consisted of plant height, number of leaves, stem diameter, ear weight, klobot / sample, ear weight with klobot / plot, ear weight without clobot / plant sample, ear weight without klobot / plot results showed the administration of durian skin biochar had a significant effect on the growth of the stem diameter of the plant with the best treatment, B3, the administration of chicken manure significantly affected the plant height with the best treatment, K3 and the combination of chicken manure and durian skin biochar had no significant effect.
