PEMANFAATAN DAUN GAMAL SEBAGAI PUPUK ORGANIK CAIR (POC) UNTUK MENINGKATKAN PERTUMBUHAN DAN PRODUKSI TANAMAN KUBIS BUNGA (Brassica oleracea L.) PADA TANAH PODSOLIK
Abstract
This study aims to investigate the response of growth and yield of cauliflower on the provision of Gliricidia
Leaves Liquid Organic Fertilizer and to determine the concentration of Gliricidia Leaves Organic Liquid Fertilizer
for the best growth and production of cauliflower. This research was conducted in experiment garden Faculty of
Agriculture Baturaja University, located in the sub district Baturaja Timur. The research started since May to July
2015. Data was analyzed by using non factorial completely randomized design, with 5 treatments were repeated 5
times, in order to get 25 units of treatment. The treatment in this study was P0 = Control, P1 = POC Leaves of
Gliricidia 15 ml / liter of water, P2 = POC Leaves of Gliricidia 25 ml / liter of water, P3 = POC Leaves of Gliricidia 35
ml / liter of water, P4 = POC Leaves of Gliricidia 45 ml / liter water. The results of this research was the giving
Gliricidia Leaves Liquid Organic Fertilizer significantly affect the growth and production. Giving POC concentration
of 45 ml / liter of water (P4) is the best treatment to improve the growth and yield of cauliflower. P4 treatment
enhances growth of cauliflower interest at 12.86% and production by 135.22% if compared to P0 treatment, with
the production of cauliflower as 10.38 tonnes per acre.
