Efecto de cuatro bioestimulantes de accion foliar sobre variables de desarrollo en el cultivo de banano

Abstract

When it comes to agricultural products at the national level, bananas are the most important crop in Ecuador's economy and the capital income they generate contributes to the country's monetary flows. In our area of ​​expertise, the lack of information on the nutritional needs of crops has limited our use of information from other banana-producing countries, but we cannot assume that the results are similar when the soil-climatic conditions are completely different. The main objective was to evaluate the effect of four foliar action biostimulants on development and production variables in an intensive banana system. The experiment was carried out at the Santa Inés Experimental Farm of the Faculty of Agricultural Sciences at the Technical University of Machala, located on the Machala-Pasaje road at Km 5.5.cA Completely Random Design (DCA) was implemented. with 5 treatments and 3 repetitions, the first treatment being applied with banatrel, the second with Yara concentrated suspensions (caltrac, magtrac, zintrac, bortrac), the third with chelated applications (Ca, B, Zn, Mg), the fourth the same chelated product was used with the difference that a higher concentration was applied and the fifth treatment served as a control. The experimental unit was composed of experimental units 16.5 m long and 3.0 m wide, each with 16 plants, with a distance between plants of 1.7 m and a distance between rows of 2.2 m. In this study, 72 banana plants from the Cavendish group, a clone of Williams, were used. The work focused on monthly foliar fertilization and all the data obtained in each experimental unit were recorded. Each treatment and repetition was identified by the label per plot, and the plants selected in it were identified by small pink labels where the number of each plant was indicated. The data collection was carried out from the first week of November, during the growth stage. For the development of this experimental work, the following variables were considered: 1) Plant Height (AP); 2) Pseudostem Perimeter (PP); 3) Number of Leaves and 4) Foliar Emission (EF) At the end of the evaluation period, the evolution of all the treatments analyzed can be defined and their effects on the variables analyzed tended not to have significant differences within each variable analyzed, these They were evaluated using parametric tests such as the t-Student analysis from week 6 and the results tracked, although in some of the variables they did obtain minimal differences. . Data were tabulated and analyzed using AGROESTAT software. As a conclusion we have that in the first weeks no differences were obtained between the treatments, but with the passing of the weeks and with the collection of data, the behavior of the plants was able to manifest minimal differences between the height variables and the foliar emission in change in the variables of stem or diameter of the pseudostem and number of leaves there were no differences.
