Efectos de la fertilización química-orgánica en el rendimiento de dos variedades de Alfalfa (medicago sativa l.), en la Comunidad de Calpaqui, provincia de Imbabura

This research took place in the community of Calpaquí, Otavalo city, Imbabura province, at a height of 2.740 mamsl. This project was carried out to evaluate the effect of the chemical - organic fertilization in the yield of two varieties of alfalfa, such as Flor Morada and Abunda Verde (50 kg/ha each one). The chemical - organic fertilization was made of excretes of cows, guinea pigs, and hens (39.250 kg/ha for each one) with diammonium phosphate (87 kg/ha), ammonium sulfate (69 kg/ha), and potassium sulphate (60 kg/ha) for each dosage of manure. Besides, here was implemented a statistical design of completely randomized blocks with a factorial arrangement of (3 x 2) + 2 and three replications; the average contrast of treatments was performed with Tukey's test at 5% of significance. Furthermore, some variables were evaluated, such as number of seedlings, plant height, number of stems per crown, leaves number, basal diameter, forage production, agronomic efficiency of fertilizer rates, economic analysis, and bromatological analysis.
