El ensayo se realizo en el Centro de Produccion y Practicas Rio Verde, propiedad de la Universidad Estatal Peninsula de Santa Elena, ubicada en la comuna Rio verde canton Santa Elena, el trabajo de investigacion tuvo como objetivo evaluar el efecto de variantes de riego en el comportamiento agronomico del maiz bajo diferentes laminas de riego utilizando como instrumento de medicion de la evaporacion la tina clase A. Los tratamientos fueron cinco dosis de riego 60, 70, 80, 90 y 100 % de la evapotranspiracion, los tratamientos se dispusieron en un diseno de bloques completos al azar con cuatro repeticiones, las medias comparadas con la prueba de Tukey  (p > 0,05). El analisis de regresion se ajusta a una ecuacion de segundo grado y el coeficiente de determinacion R 2 0,91, el mismo que muestra el alto grado de dependencia de los resultados en funcion de las variantes de riego. La mayor produccion la obtuvo el tratamiento  90% con 12,18 t.ha -1 .  Abstract Effect of irrigation variant in the corn production (Zea mays L. ) at Rio Verde commune, Santa Elena, Ecuador. The test was conducted at the Production and Practice Center Rio Verde, owned by the Santa Elena Peninsula State University, located in Rio Verde commune, Santa Elena canton, the research aimed to evaluate the effect of irrigation variations into agronomic performance of corn under different irrigation sheets using as measuring tool evaporation A class Pan. The treatments were five doses of irrigation 60, 70, 80, 90 and 100% of evapotranspiration, treatments were placed in a complete randomized design of blocks with four replications, the averages compared with the Tukey test (p> 0.05). The regression analysis fits a quadratic equation and the coefficient of determination R2 0,91 which shows the high degree of dependence of results based on irrigation variants. The highest production was obtained by the treatment with 90% with 12,18 t.ha-1.
