The Growth Response of Oil Palm Seedling at Main Nursery Against Watering at Different Volume and Frequency and Against Provision of Compost

Abstract

The purpose of this research is to know the growth response of oil palm seedling by doing watering at different volume and frequency combined with the provision of fertilizer compost during main nursery. The experiment was done from April 2017 until August 2017. It was conducted at the Ciparanje Experimental Garden, University of Padjadjaran, West Java by using random block design as the method of the experiment. Treatments consisted of volume watering (without, 1.5 l, 2 l; 2.5 l), intervals watering (without watering, every 2 days, every 3 days) which is also accompanied by provisioning compost (without, 2 kg). The results of the research show that watering volume 1.5 l - 2.5 l polybag-1 given every two or three days was the steady optimum range to favor the growth of oil palm seedling when accompanied by fertilizing with EFB compost. Watering 1.5 l polybag-1 every two days was tend to influentially good against the additional average of plant height oil palm seedling up to 12 WAP and on 16 WAP water needed was tend to be decreasing and was sufficiently sprayed every three days with the same watering volume alongside with 2 kg EFB compost fertilizing.
