dc.descriptionMaize (Zea mays L.) is a traditional crop of great economic importance in Ecuador, considered as one of the main raw materials for the industry; since a number of by-products are produced from it for human and animal nutrition. This productive chain represents about 24% of the agricultural GDP (Gross Domestic Product) and it is estimated that around 80 thousand families that live in the coastal region are involved in the production of hard yellow corn. The objective of this research was to determine the incidence of insect pests based on different levels of nitrogen fertilization, it was carried out in the Los Ríos province, Montalvo canton, "La Maravilla" Campus. The treatments used in the experimental work were 5 levels of nitrogen fertilization, the experimental plots have a planting distance of 0.80 x 0.20, with an area per plot of 5m x 5m = 20m2, the treatments were distributed in a design of complete random blocks with 4 repetitions, to determine the difference between treatments, the Tukey test was used at 95% probability. During the crop cycle, the following were evaluated: days to flowering, plant height, evaluation of the insect pest population, grain-tuff ratio, yield per hectare and economic analysis. The results established that the economic evaluation made to the treatments with the application of 140kgN / ha, found the highest utility with $ 1192.7, having the lowest income with 120kgN / ha, with $ 1074.76.es_ES

dc.description.abstractEl maíz (Zea mays L.) es un cultivo tradicional de gran importancia económica en Ecuador, considerado como una de las principales materias primas para la industria; pues de ella son elaborados un sin número de subproductos para la alimentación humana y animal. Esta cadena productiva representa cerca del 24 % del PIB (Producto interno bruto) agropecuario y se estima que alrededor de 80 mil familias que habitan en la región costa están involucradas en la producción de maíz amarillo duro. El objetivo de esta investigación fue determinar la incidencia de insectos plagas en función de diferentes niveles de fertilización nitrogenada, se realizó en la provincia Los Ríos, cantón Montalvo, Recinto “La Maravilla”. Los tratamientos utilizados en el trabajo experimental fueron 5 niveles de fertilización nitrogenada, las parcelas experimentales tienen un distanciamiento de siembra de 0,80 x 0,20, con un área por parcela de 5m x 5m=20m2, los tratamientos fueron distribuidos en un diseño de bloques completos al azar con 4 repeticiones, para determinar la diferencia entre tratamientos se utilizó la prueba de Tukey al 95% de probabilidad. Durante el ciclo del cultivo se evaluaron: días a floración, altura de planta, evaluación de la población de insectos plagas, relación grano-tusa, rendimiento por hectárea y análisis económico. Los resultados establecieron que la evaluación económica realizada a los tratamientos con la aplicación de 140kgN/ha, se encontró la mayor utilidad con $1192,7, teniendo menor ingresos con 120kgN/ha, con $1074,76.es_ES
