Peran Granulasi dan Pengayaan Terhadap Peningkatan Efektivitas Kompos pada Sawi, Selada, Kangkung, dan Bayam



This study aimed at determining the effect of granulation and compost enrichment to improve the effectivity of compost on green mustard, lettuce, kangkong, and spinach. The granulation treatments i.e without and with granulation and the enrichment using microbial cultures, the liquids from the rock phosphate fermentation, and the mixture of microbial cultures and the liquids from the rock phosphate fermentation were as treatments . The combinations of treatments were arranged using completely randomized block design with 20 replications. Variables observed were plant height, leaf number, fresh weight and dry weight. The data were analyzed using analysis of variance and foll owed by Duncan's Multiple Range Test. The results showed that there was no significant interaction between granulation with enrichment to improve the effectivity of compost on green mustard, lettuce, kangkong, spinach. The compost granulation treatment significantly increased the effectivity of compost on green mustard and lettuce, but not on kangkong and spinach. The granulation even decreased the compost effectiveness on spinach. The compost enrichments treatments significantly increased the effectivity of compost on green mustard, lettuce and spinach. The compost enrichments using the mixture of liquid fermentation medium of rock phosphate and microbial increased yield of green mustard and lettuce up to 48.4 and 60.1% respectively, while liquid fermentation medium of rock phosphate increased yield of spinach 75.0%.
