Pemanfaatan Amandemen Tandan Kosong Kelapa Sawit Pada Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensis jacq.) Periode Pre-Nursery di Tanah Ultisol

Abstract

Oil palm is an important commodity for the Indonesian economy as it produces vegetable oil that is needed by industries. Its production produces waste, including oil palm empty fruit bunches (EFB), which is expected to be utilized as compost to replace inorganic fertilizers. Ultisol is poor in nutrients such as c-organic, nitrogen, phosphorus, magnesium, potassium and low pH, and has high aluminum content. This study aims to assess the effect of giving empty palm bunches amendment (Elaeis Guineensis Jacq.) on the growth of oil palm seedlings at the pre-nursery stage in Ultisol. This research was conducted in April 2024 - July 2024 in Buntu Pane Sub-district, Asahan Regency, North Sumatera with an altitude of ± 86 meters above sea level. This study used a completely randomized design (CRD) consisting of 4 treatments with 5 repetitions, namely P0: Control, P1: 200 g Empty Palm Bunch, P2: 200 g Oil Palm Empty Bunch Biochar, P3: 200 g Oil Palm Empty Bunch Compost. Based on the results of the study, it was found that the provision of 200g of oil palm empty fruit bunch compost was the best treatment to increase the height and number of leaves of oil palm plants. The application of oil palm empty fruit bunch compost is the best treatment because it can improve soil nutrient content and support nutrient absorption by pre-nursery oil palm seedlings.
