Evaluación de Cuatro Abonos Orgánicos(Humus, Bokashi, Vermicompost y Casting), en la Producción Primaria Forrajera de la Brachiaria brizantha en la Estación Experimental Pastaza

Abstract

Pastaza Experimental Station belonging to the ESPOCH, the effect of manure humus, bokashi, vermicompost and casting was evaluated applying in doses of 4 Tn / ha in brizanta brachiaria behavior, which were compared with control treatment The (no compost), 15 research plots of 12 m2 were used under a DBCA. experimental results were subjected to analysis of variance for mean differences and separations according to the Tukey test. At the first cut, significant statistical differences were determined in canopy cover (94.11%) with humus usage and forage production (85.00 Th / ha year) in vermicompost, whereas the other parameters considered were not statistically different reaching plant grass heights to 65.39 cm, 7.99 plant / stems, leaves / stem 5.67, 76.33% basal cover and forage production in dry matter Tn / ha 18.38 per year. In the second evaluation cut, there were no statistical differences in answers up to 68.51 cm plant height, plant / stems, 7.42, 5.67 leaves / stem, basal cover 84.61%, 98.75% of air cover. Most forage production was got with the vermicompost (85 Tn / halyear) and dry matter (18.38 Tn / halyear). About soil, addition of manure reduced pH, humidity and the presence of K20, however contents are elevated NH4, P205 and MgO. It is recommend to use the vermicompost 4 Th / ha since it reached an increased green forage production.
