Efecto de un extracto de algas marinas y hormonas de crecimiento en el cultivo de maíz (Zea mays. L) híbrido DEKALB 7088 en el cantón Francisco de Orellana.

Abstract

The objective of this study was to assess the effect of a seaweed extract and growth hormones on corn (Zea mays. L) hybrid Dekalb 7088, by foliar application to determine the best treatment in Francisco de Orellana canton. The methodology used had an inductive approach, with quantitative variables achieving a descriptive scope, a Block Design Completely Randomized (DBCA) was used, with 5 treatments including 1 control, applying 4 replications, giving total 20 experimental units. For the statistical analysis, the Infostat software was used for the development from analysis of variance (ANOVA) and according to the interpretation of this, the Tukey test was used at 0.05% significance and variation coefficient was expressed as a percentage. The following variables were analyzed: plant height, stem diameter, weight of ears with husk, weight of grains without husk, number of grains per ear. By means of the statistical analysis applied, it was obtained as a result of treatment 4, which corresponds to the seaweed extract, is the first one that gives us more productivity in the corn crop, since the plants increase a greater growth, reaching an average height 205.35 cm, with a greater diameter (2.11 mm), ear weight with stalk (275.70 g), weight of grains per ear (208.18 g) and number of grains per ear (729.08). It was concluded the best treatment is the seaweed extract because it has balanced plant hormones and it is recommended for future research the development of field work using different doses of seaweed extracts to avoid affecting plant stress.
