This study aims to determine the effect of the concentration of ultra gene liquid biofertilizers and crowns compound NPK and to find out whether there is any interaction between the both of it on the growth of oil palm seedlings.This research was carried out at the main nursery land of Nusantara I Plantation Limited Company (PTPN I) Kebun Baru, Langsa City, Aceh Province from June to September 2017. This study used factorial randomized block design with 16 treatments repeated 3 times. This study consisted of two factors, namely the dose of ultra gene liquid biofertilizer 0.100, 200 and 300 ml and the dose of crowns compound NPK fertilizer 0,5,10 and 15 g. The results showed that the dose of Ultra Gen liquid biofertilizer significantly affected the stem diameter, leaf number and leaf area in almost all MSP and significantly affected the leaf area of 6 MSP. The dose of Ultra Gen liquid biofertilizer treatment has a very significant effect on the growth of oil palm seedlings, which is indicated by the parameters of the increase in stem diameter, number of leaves and leaf area, and only a significant effect on leaf area 6 weeks after observation. The dose of 200 ml of the Ultra Gen factor shows better growth than other doses. There is a real interaction on seedling growth as indicated by the parameters of the number of seedlings. The highest number of seed leaves was shown by the treatment of 100 ml / polybag ultra gen with NPK 5g/polybag (U1N1), and 200 ml / polybag with no NPK fertilization (U2N0), although not significantly different from the U0N0 and U3N3 treatment combinations, but significantly different with the combination of other treatments.

Cassava is one of the local food sources that are widely available in almost every region. Cuttings are used to plant cassava, and these cuttings will produce a number of roots and buds. The main purpose of this study was to evaluate the effect of cuttings slices model and the number of buds on the growth of Tobelo local varieties of cassava. This study employed a factorial Randomized Block Design (RBD), with the cuttings slices model as the first factor, consisting of three levels, namely: flat slice, one-sided slice and two-sided slice. The second factor is the number of buds, which is divided into three levels, 1 bud, 2 buds and 3 buds. The observation parameters in this study include plant height, number of leaves, stem diameter and leaf area. The results have revealed that the model of two-sided sliced cuttings combined with the number of one bud is the most effective treatment in improving the growth of cassava plants of Tobelo local varieties. The models of one-sided and two-sided oblique cuttings slices yield the highest average value for the parameters of plant height, stem diameter and leaf area, while the treatment with one bud tends to give the best results for the growth parameters.

<p>ABSTRACT</p><p>The accuracy of fertilizer dosage for one-year-old oil palm plants is very important. The objective of the research was to determine the optimum rates of Nitrogen and Phosphorus fertilizers for young oil palm. The experiment was conducted at IPB-Cargill Teaching Farm of Oil Palm at Jonggol, from March 2013-March 2014. This study consisted of two separate experiments namely (1) Optimizing Nitrogen and (2) Optimizing Phosphorus. Both experiments used randomized block design with one factor and three replications. The treatments were five rates of nitrogen or phosphorus (0, 135, 270, 405, 540 g N per plant; 0, 135, 270, 405, 540 g P2O5 per plant). The results showed that nitrogen fertilizer rates increased height linearly at 10 month after treatment (MAT) and quadratically at 12 MAT. Stem girth, frond production and leaf area of 9th frond increased quadratically with N rates (9, 10, 12 MAT). Nitrogen fertilizer quadratically increased leaf chlorophyll content (12 MAT), but did not significantly affected leaf-N content. Phosphorus fertilizer increased palm height linearly (9, 10 MAT) and quadratically (12 MAT). Phosphorus linearly increased stem girth (12 MAT) and quadratically (9, 10 MAT). Frond production was quadratically increased with phosphorus rates (9, 10, 12 MAT). Phosphorus linearly increased leaf area of 9th frond (9 MAT) and quadratically (12 MAT). The optimum rates of nitrogen and phosphorus fertilizers for one year old plant was 382 g N and 331 g P2O5 per plant, respectively.</p><p>Keywords: inorganic, nutrient, optimum rates, single fertilizer</p>
