Respon Aplikasi Dosis Kompos dan Interval Penyiraman pada Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensis Jacq.)

Abstract

. The objective of the study to determine the effective of compost dosage and watering interval on growth of oil palm seedling. Dosage of compost consist of 1.0, 1.5, 2.0 kg/polyibag and watering interval: every day, every 2 days, and every 3 days, watering with 1 liter of water for every seedeling with 5 kg soil/polybag. The result showed that compost dosage had signifficant effect on increasing of stem diameter palm seedling at 30, 60,90 after planting, broad of leaf at 30, 60, 90 after planting, length of root 90 days after planting, weight of fresh biomass, 90 days after planting. Growth of palm seedling best at 1.5 kg compost/polybag. Watering interval had significan effect on hight of palm seedling at 30, 60 and 90 days after planting, increasing of broad of leaf at 30 days after planting, length of root at 90 days after planting. The best growth of palm seedling found at watering interval every 3 days. There were significant interaction between compost dosage and watering interval on hight of palm seedling at 60 days after planting, increasing of palm stem diameter at 30, and 90 days after planting the best growth of palm seedling found at treatment combination 2 kg compost/polibeg and every 3 days watering interval
