Estudio comparativo de la productividad en maíz, bajo una asociación de cultivos y fertilizantes inorgánicos con diferentes aportes de nitrógeno en El Coca Orellana.

Abstract

The objective of this experimental work was to determine the corn performance (Zea mays), under an association of crops and inorganic fertilizers where different treatments were tested, alternating lower and lower doses in the presence of legumes. The methodology employed had a qualitative and quantitative approach, using the randomized block method with four treatments and three replications per treatment, applying predetermined doses in each application, generating an approach designed for the experimental research analysis which was based on applications of doses defined by the researcher considering the nutritional levels assimilated by the plant contained in the inorganic fertilizers (Yara Tera) used in the exploration. The application reductions of 5% fertilizer were established, each one lower than previous one, starting from the percentage of application recommended by the manufacturer (1kg/ha), which resulted the plants in conditions of nutritional deficiency in interaction with a crop association between corn (Zea mays) and mung bean (Vigna radiata), derived feasibly in one of treatments, due to its productivity it was determined the best treatment yielded 121695 cobs per ha giving a net income of $1. 425.38 for each hectare by corn planted. In conclusion, it was possible to reduce the application dose of inorganic nitrogen fertilizer by 5%, maintaining the yield as well as returning fertility to the soil. It is advisable to work with shorter densities, which would increase profits, and for this it would be feasible to use drones for fertilization and pest control, leaving aside the farmer's transitory trails.
