| dc.description | In Ecuador, corn is an important crop for both the economy and food security. The main production places are the coast and the mountains; the country has introduced certain hybrid varieties that have improved the productivity and sustainability of crops. The objective of this research was to evaluate the agronomic response of three corn hybrids (Zea mays L.) planted at two distances in the area of Paján, Manabí. A complete randomized block design was used with a 3 x 2 factorial arrangement randomly distributed in three repetitions. Regarding the results of the research, it was determined that the planting distances applied to the different materials influenced the obtaining of differences in the agronomic variables of the different hybrids applied. The Dekalb 8719 hybrid recorded the best plant height value at harvest with 2.29 cm and the best average ear insertion height (1.50 cm). The Dekalb 8719 treatments with a planting density of 0.20 m x 0.80 m and 0.16 m x 0.60 m presented the best average plant height of 2.29 cm and 2.28 cm, as well as a better insertion height of ears with 1.50 cm and 1.49 cm, respectively. . The Adv 9559 hybrid recorded the highest number of grains per ear with 500.50; while the interactions showed that the Adv 9559 - 0.20 m x 0.80 m treatment presented the best average of 602.33 grain number per ear. The hybrid Adv 9559 recorded the highest average ear length (19.17 cm); The interactions showed that the Adv 9559 - 0.20 m x 0.80 m treatment presented a better average of 24.33 cm. The hybrids Dekalb 8719 and Adv 9559 recorded the highest average weight of 100 grains with 42.67 and 42.33; The interactions showed that the Adv 9559 - 0.20 m x 0.80 m treatment presented a better average with 44.67 g. As for the hybrids, Dekalb 8719 recorded the highest average yield per hectare with 12318.33 kg/ha; The interactions showed that the Dekalb 8719 treatment - 0.16 m x 0.60 m presented the best average yield per hectare with 15041.32 kg/ha | es_ES |

| dc.description.abstract | En Ecuador el maíz es un cultivo importante tanto para la economía como para la seguridad alimentaria. Los principales lugares de producción son la costa y la sierra, el país ha introducido ciertas variedades híbridas que han mejorado la productividad y la sostenibilidad de los cultivos. La presente investigación tuvo como objetivo evaluar la respuesta agronómica de tres híbridos de maíz (Zea mays L.) sembrados a dos distancias en la zona de Pajan, Manabí. Se utilizó un diseño Bloques completos al azar con arreglo factorial 3 x 2 distribuidos aleatoriamente en tres repeticiones. En cuanto a los resultados de la investigación se determinó que las distancias de siembra aplicadas a los diferentes materiales incidieron en la obtención de diferencias en las variables agronómica de los diferentes híbridos aplicados. El híbrido Dekalb 8719 registro el mejor valor de altura de planta a la cosecha con 2.29 cm y el mejor promedio de altura de inserción de mazorca (1.50 cm). Los tratamientos Dekalb 8719 con una densidad de siembra de 0.20 m x 0.80 m y 0.16 m x 0.60 m presentaron el mejor promedio de altura de planta 2.29 cm y 2.28 cm, al igual que una mejor altura de inserción de mazorcas con 1.50 cm y 1.49 cm, respectivamente. El híbrido Adv 9559 registro el mayor número de grano por mazorca con 500.50; mientras que las interacciones demostraron que el tratamiento Adv 9559 - 0.20 m x 0.80 m presento el mejor promedio de 602.33 número de grano por mazorca. El híbrido Adv 9559 registro el mayor promedio de longitud de la mazorca (19.17 cm); las interacciones demostraron que el tratamiento Adv 9559 - 0.20 m x 0.80 m presento un mejor promedio de 24.33 cm. Los híbridos Dekalb 8719 y Adv 9559 registraron los mayores promedios de peso de 100 granos con 42.67 y 42.33; las interacciones demostraron que el tratamiento Adv 9559 - 0.20 m x 0.80 m presento un mejor promedio con 44.67 g. En cuanto a los híbridos, Dekalb 8719 registro el mayor promedio de rendimiento por hectárea con 12318.33 kg/ha; las interacciones demostraron que el tratamiento Dekalb 8719 - 0.16 m x 0.60 m presento el mejor promedio de rendimiento por hectárea con 15041.32 kg/ha | es_ES |
