Eficiencia agronómica del sulfato de magnesio para la emisión foliar del cultivo de maíz (Zea mays L.) en la Parroquia Isla de Bejucal, cantón Baba

Corn is a very important crop for feeding people and animals, therefore its demand is continuously growing, so it is sought to nourish the plant in a correct and timely manner. Magnesium is a macronutrient directly related to chlorophyll since it is the center of This molecule that attributes the greenness of the plants causing photosynthetic reactions of the same. Therefore, the present investigation proposes as objective to evaluate the agronomic efficiency of magnesium sulfate for the foliar emission of the corn crop (Zea mays) in the area of the Isla of Bejucal, the same that was carried out in the properties of Mr. Emilio García Villegas, located in the Isla de Bejucal parish, Baba canton, the geographical coordinates where the essay will be located in UTM are X: 9813736; Y: 650768 whose area has a humid tropical climate, with an average temperature of 24 to 26° with relative humidity of 78%, average annual precipitation of 1796,2 mm, with a height of 11 meters above sea level and 884,7 hours of annual average sunshine. Based on the results, significant effects were found in some agronomic variables of the magnesium sulfate treatments. The result of the application of magnesium sulfate had a higher response height and leaf index compared to the control. Regarding days of flowering, no statistical significance was reported between the treatments. The highest concentration of chlorophyll was found in the treatments with the application of magnesium sulfate at 30 kg/ha and 40 kg/ha. The highest grain yield was obtained in the magnesium sulfate treatment at a dose of 30 kg/ha.

El maíz es un cultivo muy importante para la alimentación de las personas y animales por ende su demanda va en continuo crecimiento por lo que se busca nutrir a la planta de manera correcta y oportuna. El magnesio es un macronutriente relacionado directamente con la clorofila ya que es el centro de esta molécula que atribuye el verdor de las plantas provocando reacciones fotosintéticas de la misma. por lo cual la presente investigación propone como objetivo evaluar la eficiencia agronómica del sulfato de magnesio para la emisión foliar del cultivo de maíz (Zea mays) en la zona de la Isla de Bejucal, la misma que se realizó en los predios del sr. Emilio García Villegas, ubicado en la parroquia Isla de Bejucal cantón Baba, las coordenadas geográficas donde se ubicará el ensayo en UTM son X: 9813736; Y: 650768 cuya zona presenta un clima tropical húmedo, con una temperatura promedio de 24 a 26° con humedad relativa de 78%, precipitación promedio anual de 1796,2 mm, con altura de 11 msnm y 884,7 horas de heliofanía de promedio anual. En base a los resultados se encontró efectos significativos en algunas variables agronómicas de los tratamientos de sulfato de magnesio. El resultado de la aplicación de sulfato de magnesio tuvo como respuesta mayor altura e índice foliar a comparación del testigo. En lo concerniente a días de floración no se reportó significancia estadística entre los tratamientos. La mayor concentración de clorofila los tuvo los tratamientos con aplicación de sulfato de magnesio a 30 kg/ha y 40 kg/ha. El mayor rendimiento de grano se obtuvo en el tratamiento de sulfato de magnesio en dosis de 30 kg/ha.
