Evaluación de la influencia físico-química en la aplicación de un abono orgánico-mineral de liberación controlada en el desempeño productivo de una mezcla forrajera

Abstract

The goal of this thesis was to introduce an alternative fertilizer, based on an organic fertilizer, manure and a mineral one, zeolite, and evaluate the physical - chemical influence on the soil. It took place in Azuay’s Province, Soldados’ Community, Pumamaqui’s Sector, and was directed by the Independent Institute for Agricultural Research (lNlAP). The experimental design was completely randomized with 12 treatments per experiment and three replicates per plot. Work was done on a pasture forage mixture established with annual rye grass, perennial rye grass, red clover and white clover, in a ratio of 80 % grasses and 20% legumes. Agronomic and physical-chemical results were processed according to the Statistical Program SPSS 22.0 version, using the Tukey test at 5%, to later be analyzed and discussed. The obtained values point out that using manure with zeolite acquired better responses in dry matter yield, final physical - chemical soil’s parameters and production costs.
