PENGARUH WAKTU DAN DOSIS KOMPOS ISI RUMEN SAPI TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KUBIS BUNGA (Brassica oleraceae L.) PADA TANAH GAMBUT

Abstract

This study aims to determine the effect of time and dose compost composting cow rumen contents on growth and yield of cauliflower (Brassica olerasea L.) on peat soil. Research using a completely randomized design (CRD) factorial with two factors. The first factor is the composting time (W) consisting of 3 levels: 15 days, 30 days and 45 days. The second factor is the dose composted cow rumen contents (D), which consists of four levels: 100 g.polybag^-1, 200 g.polybag^-1, 300 g.polybag^-1and 400 g.polybag^-1, repeated 4 times to obtain 48 units of trial. The results showed that there was no interaction effect between time composting and compost dose cow rumen contents on the growth and yield of cauliflower in the peat soil. Time composting  30 days is the best time because it can produce stover heaviest weight, ie 335.17 g.plant^-1. Composting cow rumen contents at a dose of 400 g.plant^-1 is the best because it produces a heavy dose of flowers, flower diameter and weight of the heaviest stover respectively 114.58 g.plant^-1, 9.23 cm and 385.95 g.plant^-1
