Determinación de la respuesta forrajera al uso de dos fuentes de Nitrógeno, Fósforo y Potasio Gallinaza y un Fertilizante Completo en potreros establecidos de Kikuyo, mejorados con Rye grass y Trébol blanco

Abstract

The research was conducted at the farm IRQUIS the University of Cuenca, located in Victoria del Portete-Cuenca-Azuay. at an altitude of 2,660 m.s.n.m .; Latitude and Longitude 9,659,297.287 713,529.792. We sought to evaluate the effect of using chicken manure and a complete fertilizer on the yield of MV, MS and nutritional quality of a meadow of Kikuyu grass enhanced Rye and white clover. Previously soil analysis was performed. Three treatments were evaluated: T1 Without fertilization; T2 fertilization with chicken manure; and T3 Fertilisation with complete fertilizer chemical. The amounts of fertilizers were incorporated into the meadow based on soil analysis, in a single dose at the beginning of the experiment December 2015. assessments established prairies Kikuyu Pennisetum clandestinum were performed and improved with Rye grass Lolium perenne and Lolium multiflorum and white clover Trifolium repens. The experimental design was randomized block with 4 replications for each treatment in each of the cuts. four cuts, one every 35 days were performed. Each experimental unit had 100 m2. Data were analyzed in Excel using ANOVA and Tukey test of significance of 0.05. For the production of MV significant difference p <0.05 was found between T1 and T2. T2 production MV best expressed in kg / ha in the second and third cut where it reached 21000 and 19375 kg / ha respectively was obtained; while T3 up to 17562.5 kg / ha was reached in the second cut. Production in MS, no significant differences were found. In the nutritional quality no significant differences were recorded. As for the economic analysis, it was determined that T2 has a net profit lower than the net profit achieved in T3; but is more variable cost T3 T2
