The Growth Performance of Oil Palm Seedlings in Pre-Nursery and Main Nursery Stages as a Response to the Substitution of NPK Compound Fertilizer and Organic Fertilizer

Abstract

<p>The need of nitrogen (N), phosphate (P) and potassium (K) nutrient in oil palm nursery are usually fulfilled with synthetic chemical fertilizers such as NPK fertilizer. The application of NPK fertilizer can cause the soil to become hard due to the accumulation of the residue left on the ground. Cow manure is able to substitute NPK fertilizer based on the chemical status of the soil. This study aimed at analyzing the effect of NPK fertilizer substitution with cow manure on the growth of oil palm seedlings in the pre-nurseries and main nurseries. The experiment was conducted from February to September 2018 in the Banguntapan research and experimental field, Faculty of Agriculture, Universitas Gadjah Mada. The experiment applied the Randomized Complete Block Design (RCBD) with one factor and six blocks as replications. The factors were subtitution using the replacement series method with five levels of doses, 100% NPK, 75% NPK + 25% cow manure, 50% NPK + 50% cow manure, 25% NPK + 75% cow manure and 100% cow manure. The observed parameter variables were root lenght, root area, hump diameter, leaf area, the number of leaves, plant height and plant dry matter. The use of 25% NPK substitute with 75% organic material was the best result in increasing the growth performance of oil palm seddlings in pre-nursery and main nursery.</p>

Respon Kelapa Sawit di Aplikasi Kompos Eceng dan POC Asal Tebu di Pre Nursery

“…Pada pertanian konservatif, menurut Halbrendt et al, (2014), pertanian organik merupakan salah satu tehnik yang diperkenalkan untuk membantu memecahkan masalah penipisan hara di dalam tanah. Penggunaan pupuk NPK dapat menyebabkan tanah mengeras dan meninggalkan residu (Adileksana et al, 2020). ISSN : 2085-4226 e-ISSN : 2745 Kompos merupakan salah satu bahan organik.…”

OIL PALM ECONOMIC PERFORMANCE IN MALAYSIA AND R&D PROGRESS IN 2020

“…Whilst the application of agrochemicals is an integral component in the well-being of palm, it is still not recognised as a sustainable practice and affects the soil health in the long run. Leveraging on the prospect of sustainable approaches, the mixing of 75% cow manure together with 25% nitrogen, phosphorus and potassium (NPK) compounds fertiliser was found to give the best vegetative growth among the five dosages examined on pre and main nursery seedlings (Adileksana et al, 2020). These are some of the optimisations that can be incorporated into best management practices (BMP), which has the appropriate fertiliser application in achieving optimum production.…”

Competitiveness of Palm Oil Products in International Trade: An Analysis between Indonesia and Malaysia

“…According to Lam et al (2019), products derived from this commodity are central in international trade, especially in the supply aspects, considering the fact that these derivatives are the most widely used oil products and also among the largest drivers of greenhouse gas (GHG) emissions from  Received for publication April 9, 2020 Accepted after corrections April 18, 2020 global land use and land cover change. Currently, the level of production in oil palm plantations has not been fully maximized, therefore, the need for various actions to improve this productivity (Adileksana et al, 2020). Aside being used as cooking oil, it is also a promising source of biodiesel and its demand has been increasing worldwide.…”
