| Resumo: | Corn is a crop of economic importance worldwide. The expression of genotypic and phenotypic characteristics are affected by the environmental conditions to which the plant is exposed. Therefore, the objective of this research was to evaluate the development and performance of the corn crop, to contribute with the expansion of the agricultural frontier, using four corn hybrids, during the period november – February 2016. The trial was developed in the parish of Luz de America, province of Santo Domingo de los Tsáchilas – Ecuador. The management was carried out by performing fertilization and pest control of the crop equally in all treatments, the hybrids used were; Thunder-NB-7443, Iniap-H-551, Pioneer-F30K73 and Gladiador-DOW-2B-688; The variables yield per hectare, length of the ear, diameter of the ear and weight of the ear, number of leaves, height of the plant, insertion to the ear, and ear per plant were evaluated. Where the hybrid that better developed in the zone of Luz de America was Pioneer-F., when expressing high yields in terms of production per hectare; being Trueno-NB., and Iniap-H., those that occupy statistically non-significant ranges and during most of the evaluation Gladiator DOW 2B-688; it is the least potentialized. It is concluded that corn tends to adapt, favorably to different environments, however, depending on the agroecological environment can be expressed the tolerance to stress that this generates, which is expressed through production and yield. |
