Resumen
Esta investigación se la desarrolló en la parroquia Mariscal Sucre
perteneciente a la ciudad de Milagro con coordenadas de 02°20'22'' de latitud
sur y 79°31'43'' de longitud occidental. El objetivo general de este trabajo fue
Identificar el efecto de dos niveles de fertilización a base de Boro y Magnesio
en diferentes estados presente al ciclo del maíz utilizando una fertilización
para mejorar la productividad, calidad y rentabilidad del cultivo, entre los
objetivos específicos encontramos: a) Evaluar agronómicamente el hibrido de
maíz con dos niveles de fertilización foliar con base al Boro y magnesio, b)
Realizar un estudio económico de los tratamientos estudiados. Se concluyó
que el tratamiento con 6,0 ml/L de agua de Boroned/ha (1200 mL/ha de
Boroned), presentó agronómicamente la mayor longitud de mazorca, días a
floración y peso de cien semillas; con los tratamientos de 6,0 y 9,0 mL de Eco
Magnesio/L de agua (400 y 800 ml de Eco Magnesio/ha), se obtuvo la mayor
longitud de mazorca y rendimiento de grano; La Interacción B1+ Mg2 (600 mL
de Boroned + 400 mL de Eco Magnesio/ha), presentó la mayor circunferencia
de mazorca, longitud de mazorca y peso de 100 semillas; y La metodología
de presupuesto parcial mostró que ningún tratamiento se ajustó a la Tasa
mínimo de retorno que es de 50 a 100%, no considerando rentable su
aplicación con los rendimientos de grano obtenidos.

This research was carried out in the Mariscal Sucre parish belonging to the city of Milagro with coordinates of 02 ° 20'22 '' south latitude and 79 ° 31'43 '' western longitude. The general objective of this work was to identify the effect of two levels of fertilization based on Boron and Magnesium in different states present to the corn cycle using fertilization to improve the productivity, quality and profitability of the crop, among the specific objectives are: a) Agronomically evaluate corn hybrid with two levels of foliar fertilization based on Boron and magnesium, b) Conduct an economic study of the treatments studied. It was concluded that the treatment with 6.0 ml / L of Boroned / ha water (1200 mL / ha of Boroned), agronomically presented the longest ear length, days at flowering and weight of one hundred seeds; with the treatments of 6.0 and 9.0 mL of Eco Magnesium / L of water (400 and 800 ml of Eco Magnesium / ha), the highest ear length and grain yield were obtained; Interaction B1 + Mg2 (600 mL of Boroned + 400 mL of Eco Magnesium / ha), presented the largest ear circumference, ear length and weight of 100 seeds; and The partial budget methodology showed that no treatment was adjusted to the minimum rate of return that is 50 to 100%, not considering its application profitable with the grain yield obtained.
