Evaluación del efecto de una fitohormona (ácido giberélico), un aminoácido y un bioestimulante en el rendimiento del cultivo de arroz (Oryza sativa L.) en el cantón Santa Lucía de la provincia del Guayas.

Abstract

Rice cultivation represents a significant productive item in the agricultural economy of Ecuador. The research field trial was evaluated in the Guajamba enclosure of the Santa Lucia canton. The research approach is quantitative in nature with a descriptive and correlational scope. For the experimental design, a number of six treatments and four repetitions were selected. The independent study variables are: plant height, number of tillers per m, number of panicles per m2 , number of grains per panicle, length and weight of panicles, percentage of vain and stained grains, weight of 1 000 grains and yield per hectare / plot in kg as a dependent variable. For the statistical analysis, the non-parametric ANOVA test with a significance level of 5 % was used, after the analysis a contrast test was performed to establish the differences between the different treatments. The best rates of yields were obtained with the T1 (biostimulant), at a dose of 1 liter per hectare, the cost ratio justifiable benefit the use of the product, so it is concluded feasible the use of agroecological products in rice cultivation, improving the economic utility of the producer by lower rates of return Key
