Abstract

This experiment was carried out to determine the efficiency of inorganic fertilizer in the main nursery of oil palm with the application of empty fruit bunches and the addition of local microorganisms (MOL) Mucuna bracteata. The experiment was conducted by using a factorial design, arranged in a completely randomized design with three replications. The first factor was the dose of inorganic fertilizer (100%, 75%, 50%, 25% ), the second factors was dose of empty fruit bunhes (efb) compost (0%, 15%, 30%, 45% by volume), and the third factor was concentration of local microorganisms (MOL) M. bracteata (no,5%,10%). The results showed that the application of 25% inorganic fertilizer in the main nursery provide of oil palm seedling growth equal to 100% inorganic fertilizers. The application of 15% oil palm empty fruit bunches compost in the main nursery of regosol soil can replace inorganic fertilizer. Granting MOL Mucuna bracteata with a concentration of 5% to 10% have not been able to increase the growth of oil palm seedlings in the main nursery. Granting of oil palm empty fruit bunches can increase inorganic fertilization efficiency in the main nursery of oil palm.Keywords: fertilizer, efb, MOL, oil palm seedlings, main nursery

Abstract

The aim of this research was to determine the effective volume of water in several types of soil for the growth of Mucuna bracteata. This research was conducted at the Education and Research Garden (KP-2) of the Stiper Agricultural Institute located in Maguwoharjo, Sleman, DIY. This study uses factorial experiments arranged in Completely Randomized Design (CRD) consisting of two factors and five replications. The first factor was the volume of water spray/day/plant consisting of four volume levels, namely: 50 ml, 100 ml, 150 ml and 200 ml. The second factor was the type of soil consisting of three types of soil, namely : regosol, latosol and grumusol. The results of the research data were analyzed using variance (Analysis of variance) at a real level of 5%. Data that is significantly different is continued with Duncan's multiple distance test or DMRT (Duncan multiple range test) at a real level of 5%. The results showed that there was no good combination of the volume of water and soil type on the growth of Mucuna bracteata. The volume of 50 ml / plant water was sufficient to produce good Mucuna bracteata plant growth. Mucuna bracteata plants can grow in regosol, latosol, and grumusol soil types.Keywords: volume, water, soil type, Mucuna bracteata

Abstract

Seedling performance is a prerequisite for successful palm oil cultivation. Determining the growth of seedlings in addition to genetic factors can also be influenced by the provision of nutrients at the beginning of growth. This research was conducted with the aim to get the best combination of cow manure with urea and NPK on the growth of oil palm seedlings in pre-nursery. This experiment used a factorial design, consisting of a single factor arranged in a completely randomized design (CRD), which is a combined application of cow manure, urea fertilizer and NPK fertilizer consisting of 4 combination levels (0.4 g urea + 0.4 g NPK; 0.2 g urea + cow manure fertilizer, 0.2 g NPK + cow manure fertilizer, and 65 g cow manure fertilizer). Research data was analyzed using Analysis of Variance (ANOVA) at 5% significance level. The results showed that administration of a combination of 0.2 g urea + 40 g cow manure produced the best growth of oil palm seedlings, although it had the same effect as a combination of 0.4 g NPK fertilizer + 50 g cow manure, whereas the combination treatment of 0.4 g urea + 0.4 g NPK fertilizer and 65 g cow manure treatment resulted in lower growth of oil palm seedlings.DOI: 10.37637/ab.v3i1.419
