EFECTOS DE HORMONAS VEGETALES DE RIZOGÉNESIS EN LA PRODUCCIÓN DEL CULTIVO DE MAÍZ (ZEA MAYS. L)

Abstract

The objective of this research work was to evaluate the applications of brassinosteroids and their analogues in corn cultivation. It is carried out on the land of the “Rancho Alegre” farm located at km 1.5 of the Ventanas - Echeandía road, province of Los Ríos. The EMBLEMA corn hybrid material was used as planting material, which is more adapted to the area. The treatments were comprised of the different levels of the foliar fertilizer Gibberellic acid + Indole-3-ylacetic acid + Brassinolide, in doses of 10, 20, 30 and 40 g/ha; plus a control treatment without application. The Random Complete Blocks experimental design was used with five treatments and 4 repetitions, the significance test used was Tukey's at 95% probability. All the necessary agricultural tasks were carried out in the cultivation of corn for its normal development, such as soil preparation, sowing, irrigation, fertilization, weed control, phytosanitary control and harvest. To estimate the effects of the treatments, the following data were taken: plant height, ear insertion height, ear length, number of grains per ear, number of grain rows per ear, weight of 100 seeds, yield, analysis economic. From the results obtained, it was determined that the foliar fertilizer based on brassinosteroids applied in the T2 treatment with a dose of 20 g/ha, showed the highest averages in the variables number of grains per ear, number of rows per ear, weight of 100 seeds. (g) and yield (kg/ha).
