Bio fertilization of Oil Palm (Elaeis guineensis Jacq.) crop in nursery phase

Oil palm (Elaeis guineensis Jacq.) is a crop with conservation vocation being a perennial plantation, managing to occupy grounds that stop other cultures can be marginal, to manage to produce organic oil of palm, would increase the environmentalist propensity of the same one. The objective of this work was to determine the dose and application way of vermicompost at level of the breeding ground. It was made in an area of a tropical very thy forest, located in Maracaibo-Venezuela. Plants of 20 cm of the Asvro*Deli hybrid was used seeded in bags of 23 kg. Six treatments were evaluated, vermicompost (VE), to three doses (0, 15 and 30% of the mixture with ground in stock-market), with and without the weekly application of the liquid extraction of vermicompost (L) (in a relation a solid part VE by 15 parts of water), in a totally at random experiment with four replications. Plant growth, number of leaves, wide of leaflet, stipe diameter and fresh biomass of the foliage was evaluated. Significant differences (P<0.05) were found between treatments for height of plant, wide biomass and leaflet with 1.15 +/- 8,01 m for VE15%+L; 773.33 +/- 106 g for VE30% and 1.85 +/- 0.13 cm for VE15%+L respectively. Differences for the other variables were not registered. It is possible to produce in breeding ground plants of oil palm for seedtime in field, only in organic form, with the use of VE 15% in the mixture of ground of stock-market and weekly applications of L to the foliage and soil.
