Caracterización de las variedades del maíz para el desarrollo de productos en la empresa Asopromaiza del cantón Célica de la provincia de Loja

Abstract

Abstract: The production of fodder for cattle in our province is deficient, and is marked by seasonality that does not allow to maintain a uniform production throughout the year. The investigation was carried out in the Gonzanamá canton, Loja province, Ecuador. The objective was the evaluation of the yield of biomass of the cultivation of zarandaja and the nutritional quality of the silage of the same in the stages of: pre-flowering, flowering, filling of legumes and fruiting. For the calculation of biomass, 4 random gauges were made in different parts of the crop with a wooden square of 1m2, and with a scale the production in kg/m2 was measured. Subsequently, the forage was dehydrated 24 hours before being processed at the Lanzaca Productive Development Center; the containers were black covers of low density polyethylene. The silage was fermented for forty-five days, later the samples were sent for nutritional analysis in the laboratories of Agrocalidad Ecuador. The results show that, the best phenological stage to obtain a food with excellent organoleptic and nutritional characteristics is pre flowering.
