Jur.2013Palm nurseries in large scale requires a lot of planting medium, so it is necessary to use some alternative media sources, so as not to focus only on the use of top soil, peat and soil that dominates the PMK is riau area with few weaknesses, so that the need to test the use of the singular or combined enriched with the addition of various organic materials. The research was conducted at the experimental farm of the Faculty of Agriculture University of Riau in June 2012 - September 2012 with the aim of knowing the effect of organic fertilizer, planting medium, and their interactions, as well as determine the best treatment, the growth of oil palm seedlings. Research Methods factorial experiment in completely randomized design (CRD), 2 factors, four levels of organic fertilizer (chicken cage, Sludge, Organic Liquid Fertilizer, Organic Fertilizer Without) and three levels of planting medium (Peat, PMK, Peat Combined with PMK) with 3 replications. Parameters measured were high accretion seeds, increase the number of leaves, tubers accretion diameter, root volume, wet weight berangkasan plants. Data were statistically analyzed, and followed by test Ducan's New Multiple Range Test (DNMRT) at the level of 5%. The results showed that the organic fertilizer can increase seedling height, number of leaves, tubers diameter, root volume and wet weight, giving the peat media tends to increase the diameter of the stump. The best combination seen in the treatment of organic liquid fertilizer (PCO) torch 20 ml with peat soil from the number of leaves, tubers diameter, root volume and wet weight. Recommended using planting medium Peat and organic liquid fertilizer (PCO) torch 20 ml, to get a quality oil palm seeds.otherPalm nurseriesstudent Paper Post Degree
