Resumen
El maíz es una de las gramíneas más importantes en el Ecuador, tiene un aporte del 3
% del 10 % del PIB que genera la actividad agrícola en el país, además es generador
de muchos empleos para las familias rurales ecuatorianas. Con un aproximado de
500 000 hectáreas, es el único cultivo que está sembrado por todo el territorio
nacional. Con la siguiente investigación se busca encontrar el mejor fertilizante
acondicionador Sfera, para mejorar la asimilación de nutrientes por parte del cultivo
de maíz en el sector conocido como GD del cantón Bucay, para ello se evaluaron
diferentes variables para la determinación del mejor tratamiento. Se escogieron 20
plantas para evaluar los tratamientos, donde nos arrojó diferencia significativa en las
variables peso de raíz, donde T1 obtuvo el mejor valor con 6.705 gramos, T4 fue
quien tuvo el menor valor con 4.752 gamos, la variable peso de mazorca T1 se
destaca con 29.59 gramos y en la variable rendimiento T1 ocupa el valor más alto con
147 quintales por hectárea siendo T3 el de menos producción con 121 quintales por
debajo del testigo que obtuvo 122 quintales.
Corn is one of the most important grasses in Ecuador, it has a contribution of 3 of 10 of the GDP generated by agricultural activity in the country, it is also a generator of many jobs for rural Ecuadorian families. With an approximate of 500 000 hectares, it is the only crop that is planted throughout the national territory. The following research seeks to find the best Sfera conditioner fertilizer, to improve the assimilation of nutrients by the maize crop sector known as GD Bucay Canton, for which different variables were evaluated to determine the best treatment. Twenty plants were chosen to evaluate the treatments where we found a significant difference in root weight variables, where T1 obtained the best value with 6,705 grams, T4 was the one with the lowest value with 4,752 grams, the variable weight of ear T1 stands out with 29.59 grams and in the variable yield T1 occupies the highest value with 147 quintals per hectare, with T3 being the least productive with 121 quintals below the control that obtained 122 quintals
