Aplikasi Pupuk Npk Tablet dan Pupuk Organik Pada Pembibitan Kelapa Sawit Main Nursery di Medium Subsoil Tanah Ultisol

Abstract

To produce a good oil palm seedlings in nutrient-poor medium then carried inorganic fertilizer (NPK Tablet) and Organic fertilizer (Biotrikom) to meet the nutrient needs of plants. This research aims to produce oil palm seedlings are of good quality. The experiment was conducted for 3 months, starting in July 2012 to October 2012. The experiment was conducted in Unit, Faculty of Agriculture Experimental Station Riau. The design used was a factorial arranged in RAL comprising two factors: The first factor is the provision of fertilizer Biotrikom comprising 4 levels, ie T0 = Without fertilizer Biotrikom / polybag, fertilizer Biotrikom T1 = 50 g / polybag, T2 = fertilizer Biotrikom 100 g / polybag, fertilizer Biotrikom T3 = 150 g / polybag, Factor II is Sigi NPK fertilizer tablet comprised of P0 = Without NPK fertilizer Tablet Sigi / polybag, P1 = Giving NPK Sigi Tablet 1 Tablet / polybag, P2 = Giving NPK Sigi Tablet 2 Tablet / polybag, and P3 = Giving NPK Sigi 3 Tablet Tablet / polybag. Then further tested with DNMRT at 5% level. Parameters measured were seedling height increment (cm), in the number of leaf (blade), increase seed tuber diameter (cm), canopy dry weight (g), root dry weight (g), ratio of crown roots and seed quality index. Based on this research, Tablet turns giving Sigi NPK showed no apparent effect on all parameters, whereas fertilizer Biotrikom significant effect on seedling height parameters, stump diameter, canopy dry weight and root dry weight. Further test results show the interaction of NPK Sigi Tablet 2 Tablet / polybag with fertilizer Biotrikom 150 g / polybag provide the best growth parameters of leaf number, diameter ratio and crown root weevil.
