Tanggap Pertumbuhan Dan Produksi Jagung Pioneer 23 Terhadap Berbagai Komposisi Vermikompos Dan Pupuk Anorganik

Abstract

Growth and yield response of maize Pioneer 23 on the several compotitions of vermicompost and inorganic fertilizers. Maize is a staple food after rice and has significant impact on the development of industry in Indonesia. Increased maize production is accompanied by the use of inorganic fertilizer. The application of inorganic fertilizer continuously without the use of organic matter results in land degradation. A solution to solve this problem is to use vermicompost which is basically the conversion of organic material by earthworms. The research was conducted to investigate response of the growth and yield of maize Pioneer 23 variety to several compotitions of vermicompost and inorganic fertilizers, using Non factorial Randomized Block Design with 11 treatments, which were P0 (control); P1 (vermicompost 2,5 kg/plot); P2 (N, P, K fertilizer 100 %); P3 (vermicompost 2,5 kg/plot + N, P, K fertilizer 100 %); P4 (vermicompost 2,5 kg/plot + N, P, K fertilizer 75 %); P5 (vermicompost 2,5 kg/plot + N, P, K fertilizer 50 %); P6 (vermicompost 2,5 kg/plot + N, P, K fertilizer 25 %); P7 (vermicompost 2 kg/plot + N, P, K fertilizer 100 %); P8 (vermicompost 2 kg/plot + N, P, K fertilizer 75 %); P9 (vermicompost 2 kg/plot + N, P, K fertilizer 50 %); and P10 (vermicompost 2 kg/plot + N, P, K fertilizer 25 %).The results showed that the several compotitions of vermicompost and inorganic fertilizers had no significant effects on all parameters, except for the plant diameter and 100 grain weight
