PENGARUH POC LIMBAH RUMAH TANGGA DAN NPK ORGANIK TERHADAP TANAMAN KUBIS BUNGA (Brassica oleraceae Var. botrytis) PADA PERTANIAN ORGANIK

Abstract

Research entitled Effect of Liquid Organic Fertilizer of Household Waste and organic NPK on Cauliflower (Brassica oleraceae Var. botrytis) of Organic Farming had been conducted at the experimental garden of the Faculty of Agricultre, Islamic University of Riau. The purpose of this study was to determine the effect of household waste liquid and organic NPK on cauliflower of organic farming. The experimental design used was a factorial completely randomized design consisting of two factors. The first factor was liquid organic fertilizer of household waste which consisted of 4 level that is 0, 5, 10, 15 cc/l water/polybag and the second factor was organic NPK which consisted of 4 level that is 0, 15, 30, 45 g/polybag. The parameters observed were as follow: plant height (cm), number of leaves (sheet), flowering age (day), relative growth rate (g/day), net assimilation rate (mg/cm²/day), harvest age (day), yield weight (g), root volume (cm³), harvest index, and root shoot ratio. Data were statistically analyzed and followed by Honesty Significant Different test at the 5% level. The results showed that the between liquid organic fertilizer of household waste and organic NPK effect significant on parameters: plant height, number of leaves, flowering age, relative growth rate, net assimilation rate, yield weight and root volume. The best combination liquid organic fertilizer of household waste concentration 15 cc/l water/polybag and organic NPK dose 45 g/polybag.
