Abstract

Research objectives to see the effect and best dose of empty widow ash application on the growth of This research was carried out experimentally using a factorial Complete Randomized Design (RAL), which consisted of two factors, namely A (empty ash), consisting of 3 levels, and factor N (NPK) consisting of 3 levels, and each there were 3 tests, the number of experimental units was 27 plots, each plot consisted of 3 plants and 2 plants as samples,  so that the whole plant is 27 x 3 = 81 plants. The level of factors is as follows: ,Factor A: A:Abu janjang empty with 3 levels, namely A0: Without giving empty janjang., A1: Giving Abu Janjang empty 325 gr /polybag, A2: Giving empty janjang ash 750 gr /polybag. Factor N: fertilizer application (NPK) with 3 levels, namely N0: Without applying NPK fertilizer, N1: Applying NPK fertilizer 1.25 gr / Polybag, N2 : Applying NPK fertilizer 2.50 gr / Polybag. Based on the results of the research that has been carried out, namely the combination of empty janjang ash and NPK fertilizer in peat medium, the following conclusions can be drawn: The application of Empty Janjang Ash at a dose of 325 gr / Polybag gives the best results against the parameters of plant height and leaf area. The application of empty janjang ash at a dose of 750 gr / Polybag gave the best results on the stem diameter of oil palm plant seedlings in the Pre-Nursery, The application of NPK fertilizer at a dose of 1.25 gr / Polybag gives the best results against the parameters of plant height, stem diameter and leaf area of oil palm plant seeds in the Pre-Nursery. The interaction of Empty Janjang Ash and NPK Fertilizer has a significant influence on the height parameters of oil palm plant seeds. Doses of Empty Janjang Ash (325 gr / Polybag) and NPK Fertilizer (1.25 gr / Polybag) provide the best results against the height parameters of oil palm plant seeds in the Pre-Nursery.
