Respuesta del cultivo de maíz a la fertilización orgánica y mineral en el cantón Pasaje.

Abstract

Maize, (Zea mays L), has played a fundamental role in diet and cultural heritage throughout time. The connection between production and fertilization is closely linked, so special attention has been paid to fertilization practices to understand how maize plants react to this process. The objective of the research was to determine the effect of organic and mineral fertilization on agro-morphological parameters in the maize crop, for applicability in the appreciation of productive capacity. The experiment was carried out in the Pasaje canton - El Oro province, at 30 meters above sea level. A Latin square design (LCS) was used. The study factor was the application of organic and mineral fertilizers to the corn crop, with five treatments and five replications. A one-factor analysis of variance between groups was used to identify possible statistical differences among the different treatments. The variables evaluated were: plant height, leaf length, leaf width, stalk diameter, fruit weight (ear and seed). The incorporation of mineral fertilizer at a dose of 200 kg/ha (Nitrogen) in ear yield obtained 2.98 t/ha, numerically surpassing the treatment of organic fertilizer at a dose of 200 kg/ha (compost) which obtained 2.92 t/ha, although the differences did not reach statistically significant levels, it is important to recognize the differences between treatments.
