Effect of Oil-Palm-Empty-Fruit-Bunch Granular Organic Fertilizer on The Yield 0f Oil Palm Fruit

Abstract

ABSTRACT Pakcoy (Brassica rapa L.) is a vegetable crop and important to human body because it contains good nutrition. Productivity of pakcoy is still low in Indonesia for some reasons, such as cultural technology. One of the efforts to increase the production of pakcoy is the application of liq- uid organic fertilizer (LOF) from jering pods. LOF can be absorbed by plants faster than solid organic fertilizers and it does not damage soil structures as synthetic chemical fertilizers did. This study was aimed to determine the optimum concentration of LOF of jering pods on growth and yield of pakcoy. The research was conducted at the greenhouse and Laboratory of Agroecotechnology, the University of Bengkulu. The re- search was organized in Completely Randomized Design (CRD) with a single factor and repeated 5 times. The LOF concentration consisted of 5 levels included LOF 0% (Control), LOF 25%, LOF 50%, LOF 75%, and LOF 100%. The result showed that the concentration of LOF 100% pro- duced the best growth and yield of pakcoy and has the longest shoot, the highest number of leaf, the widest leaf area, the heviest fresh weight of shoot, the highest weight of dried biomass, the highest greenish leaves, and the haviest weight of dried roots.
