Fertilizing is an important part in the management of palm oil nursery. The use of nitrogen fertilizer requires special attention because it is closely related to greenhouse gas emission. Alongside the application of sustainability principles at palm oil plantation, the absorption effectivity of nitrogen becomes the main concern to reduce greenhouse gas emission. The symbiosis of arbusculal mycorrhyzal fungi (AMF) becomes an important part to increase the absorption of many nutrition elements as well as reduce the pollution potential. The objective of this research is to understand the role of AMF on the prenursery growth on several intakes of urea fertilizer. The research consists of factorial treatment with several treatments: AMF application frequency: without AMF, AMF application during plantation, and application upon seedling planting and one month after that. The treatment using nitrogen fertilizer consisted of 3 levels: 0, 0.5, and 1.0 gram/seed. Research results showed that AMF application when and one month after seedling planting can increase the prenursery growth of palm oil seed, especially its biomass and the growth of the root. The dosage difference of nitrogen fertilizer caused different seed growths. The 0.5 g/seed dosage tended to result in best oil palm nursery growth compared to other dosages. There is a tendency that the application of nitrogen at 1.0 gram/seed suppressed the AMF colonization at palm oil root growth. Keywords: arbuscular mycorrhyzal fungi, nitrogen fertilizer, palm oil seed, pre nursery

Nursery is the beginning of the process to reach optimum production, so proper treatment is necessary. To reduce side effects on the environment and higher fertilizing costs, we employ mycorrhyza that is expected to increase efficiency and effectiveness of the production process. The purpose of this research is to understand the effects of mycorrhyza application on the vegetative growth of palm oil at the main nursery. This research is using non-factorial Randomized Completely Block Design with 4 (four) treatments and six repetitions that used 24 samples by observing the growth of the tree trunk, its diameter, and number of leaves. The last observation was conducted to know the degree of mycorrhyza infection in every treatment. The results showed that mycorrhyza application had no significant effect on the growth of the plant and trunk diameter, but it has very significant effect on the growth of the leaves at the last week. The more significant result was observed at M3 with 75 gram dosage. The infection degree at the end of the research showed a very significant effect with average value of 6.00 at M3 compared to M1 with 4.00 value. Keywords: mycorrhyzae, oil palm, main mursery

The aim of the study was to determine the effect of volume of solid bioslury and soil type on the growth of pre-nursery oil palm seedlings. This research was conducted at the Education and Research Garden, STIPER Agricultural Institute, located in Maguwoharjo, Sleman, Yogyakarta. The experimental design used was a completely randomized design consisting of two factors and four replications. The first factor was the bioslury volume consisting of five levels (0% + chemical fertilizer, 10%, 20%, 30% and 40%) and soil types consisting of three types (regosol, latosol, and grumosol). The data of the research were analyzed with analysis of variance at a real level of 5%. Data that was significantly different was further tested with 5% DMRT (Duncan Multiple Range Test). The results showed that there was no good combination of bioslury volume and soil type on the growth of pre-nursery oil palm seedlings. The 10% bioslury volume has the same effect as bioslury 20% and 40% but is better than 30% volume and chemical fertilizer. The use of regosol and latosol soils has the same and better effect than grumosol soil on the growth of oil palm seedlings in the pre nursery. Kata kunci : bioslury, regosol, latosol, grumosol, palm oil
