Resumen
La presente investigación se realizó en la Unidad Educativa Galo
Plaza, recinto Ánimas, Daule, Guayas, se utilizó el diseño de bloques
completamente al azar con arreglo factorial (5 x 2). Se estudiaron
Cinco híbridos de maíz (Somma, INIAP H 551, Trueno, Agri 104,
Insignia 105 con dos distanciamientos de siembra (0.20 x 0.70 cm y
0.40 x 0.80 cm). Se evaluaron las siguientes variables: altura de planta
(cm), altura de inserción de la mazorca (cm), longitud de la mazorca
(cm), diámetro de la mazorca (cm) número de hileras de granos por
mazorca, peso de la mazorca (g), peso de 100 granos (g), rendimientos
(kg/ha) y análisis económico. De acuerdo a los resultados se concluyó:
La mayoría de las variables fueron no significativos respecto a los
híbridos, distancias de siembra y su interacción; el híbrido Insignia 105
alcanzó la mayor inserción de mazorca, mientras que el promedio más
bajo de esta variable fue para el material Somma, con los dos
distanciamientos de siembra (0,20 x 0,70 m y 0,40 x 0,80 m); En la
metodología de presupuestos parciales se obtuvieron tasas muy
elevadas debido a la poca variación de los rendimientos de grano.
The present investigation was carried out in the Galo Plaza Educational Unit, Animas enclosure, Daule, Guayas, the completely random block design with factorial arrangement (5 x 2) was used. Five maize hybrids were studied (Somma, INIAP H 551, Thunder, Agri 104, Insignia 105 with two planting distances (0.20 x 0.70 cm and 0.40 x 0.80 cm) .The following variables were evaluated: plant height (cm), height of cob insertion (cm), ear length (cm), ear diameter (cm) number of rows of grains per ear, weight of ear (g), weight of 100 grains (g), yields (kg / ha) and economic analysis According to the results it was concluded: Most of the variables were not significant with respect to the hybrids, planting distances and their interaction, the Insignia 105 hybrid reached the highest ear insert, while the lowest average of this variable was for the Somma material, with the two planting distances (0.20 x 0.70 m and 0.40 x 0.80 m) In the partial budget methodology, very high rates were obtained to the little variation of grain yields.
