Abstract

Penelitian ini bertujuan untuk Mendapatkan dosis yang tepat dan melihat pengaruh dari pemberian pupuk kandang kotoran kuda terhadap pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq.) di main nursery. Penelitian ini menggunakan metode eksperimen Rancangan Acak Lengkap (RAL), dengan 5 perlakuan 5 ulangan. Perlakuan yang diberikan yaitu Tanpa Perlakuan, 200 gram Kotoran Kuda/ polybag, 400 gram Kotoran Kuda / polybag, 600 gram Kotoran Kuda / polybag, 800 gram Kotoran Kuda / polybag. Media tanam yang digunakan dalam penelitian ini adalah tanah Ultisol. Peubah yang diamati yaitu tinggi tanaman, diameter bonggol, jumlah daun, panjang daun, lebar daun, dan ratio tajuk akar. Hasil penelitian menunjukan bahwa pemberian pupuk kandang kotoran kuda terhadap pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq.) di main nursery memberikan pengaruh nyata pada tinggi tanaman, diameter bonggol, dan lebar daun. Sedangkan pada jumlah daun dan lebar daun tidak memberikan pengaruh. Dosis terbaik pada perlakuan pupuk kandang kotoran kuda terhadap pertumbuhan bibit tanaman kelapa sawit pada fase main nursery adalah 200 g/polybag. Kata kunci : kelapa sawit, kotoran kuda, main nursery THE EFFECT OF APPLICATION DOSES OF HORSE MANURE FERTILIZER ON THE GROWTH OF OIL PALM SEDDING (Elaeis guineensis Jacq.) IN MAIN NURSERY This study aims to get the appropriate dose of horse manure on the growth of oil palm seedlings (Elaeis guineensis Jacq.) in main nursery. This study uses an experimental method Complete Randomized Design (CRD), with 5 treatments 5 replications. The treatment were is without fertilizer, 200 gram horse manure / polybag, 400 gram horse manure / polybag, 600 gram horse manure / polybag, 800 gram horse manure / polybag. The planting medium used in this study was Ultisol soil. The variables observed were plant height, hump diameter, number of leaves, leaf length, leaf width, and root canopy ratio. The results showed that the application of horse manure to the growth of oil palm seedlings (Elaeis guineensis Jacq.) on main nursery had a significant effect on plant height, hump diameter and leaf width.
