Pengaruh Beberapa Media Tanam dan Varietas terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensies Jacq.) Selama Masa Pre-Nursery

Pengaruh komposisi media tanam dan jenis varietas terhadap pertumbuhan bibit kelapa sawit selama masa pre-nursery merupakan tujuan dari penelitian ini dan telah dilakukan pada bulan Februari sampai Mei 2022 di Balai Penelitian Pertanian/ Gardu Induk Kebun Organik Universitas Syiah Kuala Darussalam Banda Aceh dan Laboratorium Fisiologi Tumbuhan. Rancangan yang digunakan yaitu Rancangan Acak Kelompok (RAK) pola faktorial 3x3 menggunakan tiga ulangan. Faktor yang diteliti ada 2 faktor yaitu media tanam yang terdiri dari media tanam top soil, top soil : kompos, dan top soil : cocopeat serta 3 jenis varietas yaitu varietas topaz 1, topaz 2, dan dumpy. Terdapat interaksi yang sangat nyata terhadap peubah tinggi tanaman umur 30, 60, 90, dan 120 HST dengan kombinasi perlakuan terbaik ditemukan pada media top soil : kompos dengan varietas topaz 1. Serta terdapat interaksi yang nyata pula terhadap peubah diameter batang umur 90 dan 120 HST, dan peubah bobot berangkasan basah dengan kombinasi terbaik pada media top soil : kompos dengan varietas topaz 2.The Influence of Several Planting Media and Varieties on the Growth of Oil Palm (Elaeis guineensies Jacq.) Seedlings During the Pre-Nursery PeriodThe effect of the composition of the planting medium and the type of variety on the growth of oil palm seedlings during the pre-nursery period is the goal of this research and was carried out from February to May 2022 at the Agricultural Research Institute/Organic Garden Substation, Syiah Kuala Darussalam University Banda Aceh and the Plant Physiology Laboratory. The design used was a 3x3 factorial randomized block design (RBD) using three replications. The factors studied were 2 factors, namely the planting media which consisted of top soil, top soil: compost, and top soil: cocopeat and 3 types of varieties, namely topaz 1, topaz 2, and dumpy varieties. There was a very significant interaction with the variable plant height aged 30, 60, 90, and 120 DAP with the best treatment combination found in top soil media: compost with topaz variety 1. Also there was a significant interaction with the variable stem diameter aged 90 and 120 DAP, and wet tree weight variables with the best combination on top soil media: compost with topaz variety 2.
