Resumen
El arroz como un producto de histórica tradicional alta demanda en el
Ecuador, requiere de sistemas de cultivo que incrementen los rendimientos de
las cosechas, disminuyendo sus costos de producción unitario, a fin de que los
agricultores obtengan satisfactorias ganancias que mejoren sus condiciones
económicas.
En apoyo al enfoque de estas aspiraciones, el presente trabajo de
titulación, ofrece una investigación acerca del Efecto de tres láminas de
inundación sobre el comportamiento agronómico de tres variedades de arroz¨,
con la finalidad de incrementar los rendimientos del cultivo y los ingresos de
los productores.
La investigación se realizó durante la estación seca del año 2015, en los
terrenos del señor Genaro Orellana Cordero, perteneciente al sector Vainillo,
cantón El Triunfo, provincia del Guayas, cuya localización geográfica es
longitud Oeste: 79°31’43”, latitude Sur: 02°20’22” con una altura promedio
de 35 msnm.
La metodología empleada para la realización de este estudio consistió en
un diseño de parcelas divididas, donde los tratamientos correspondieron a las
láminas de inundación y los subtratamientos a las variedades de arroz,
utilizando cuatro repeticiones.
Los efectos de los tratamientos se evaluaron sobre el comportamiento
de determinadas características agronómicas del cultivo, cuyos resultados
expresan que estadísticamente no hubo diferencias significativas en ninguno de
los tratamientos establecidos, no obstante, las consabidas diferencias

Rice as a product of historical traditional high demand in Ecuador, requires cropping systems that increase crop yields, reducing production costs unit, so that farmers get satisfactory profits to improve their economic conditions. In support of the approach of these aspirations, titling this work provides a research on the effect of three sheets of flooding on the agronomic performance of three varieties of rice, with the aim of increasing crop yields and incomes the producers. The research was conducted during the dry season of 2015, on the grounds of Mr. Genaro Orellana Cordero, belonging to Vainillo sector Canton El Triunfo, Guayas province, whose geographical location is west longitude: 79 ° 31'43 "South latitude : 02 ° 20'22 "with an average height of 35 meters. The methodology for conducting this study was a split plot design, where treatments were flooding sheets and subtratamientos varieties of rice, using four replicates. The effects of treatments were evaluated on the behavior of certain agronomic crop characteristics, the results expressed statistically no significant differences in any of the treatments set, however, the usual arithmetic differences in yields, when projected to one hectare crop were equivalent to sales revenue, whose profits were highly profitable for the treatment of SFL variety - 11 flood sheet of 15 cm, results, be adopted by the producer, improve rice production and their level of lifetime.
