Optimasi Pupuk Dolomit pada Tanaman Kelapa Sawit (Elaeis guineensis Jacq.) Belum Menghasilkan Umur Satu Tahun

Abstract

This research aims to determine the optimum rate of fertilizer dolomit on oil palm plant aged one year. This experiment was conducted at the IPB-Cargill Palm Oil Teaching Farm, Jonggol, Bogor from March 2013 to March 2014. The design used is randomized complete block design with three replications and one factor was dolomit fertilizer rates i.e. 0, 200, 400, and 600 g plant-1. Each experimental unit consisted of 5 plants, so the number of samples is 60 crop plants. Dolomit fertilizer affected vegetative and physiology variables. Based on the plant height the rates of dolomit fertilizer recommendations for plant oil aged one year is 306.4 g dolomit plant-1.
