Dinámica del desarrollo vegetativo del banano mediante estimulación radical bajo un sistema de riego por gravedad

Abstract

Introduction. The root system in the banana plant is essential for vegetative development. Goal. To evaluate the effect of different root stimulation programs on the vegetative development and nutritional status of banana crops under a gravity irrigation system. Materials and methods. The research was carried out from November 2021 to July 2022, at the Santa Bárbara banana farm, located in the El Cambio parish, in the Machala canton, southern zone of the Province of El Oro -Ecuador. Using 6 treatments: T1 Witness (T.E), T2 Traditional aeration (A.T), T3 Radical biostimulant (BR), T4 Humic acids (A.H), T5 (BR+AH), T6 Aeration in the form of carving (A.T), with the following variables: height of the mother and offspring plant, diameter of the pseudostem, foliar emission, foliar emission at flowering, chlorophyll level, total root mass, percentage of functional root and percentage of non-functional root. A randomized complete block experimental design (DBCA), with 4 replications, analysis of variance with Agroestat ® software was applied. Results. No significant difference was obtained; but if numerical, within the results obtained, the following stand out: variable (H) better efficiency T3 4.07m, variable (H.A) better efficiency T3 1.71m, variable (D.P) better efficiency T3 106.06 cm, variable (E.F) better efficiency T6 23.00, variable (E.F.F) greater significance T1 9.87, variable (N.C) greater expression of its chlorophyll T3 59.10, variable (M.T.R) greater expression T6 41.55g, variable (R.F) better efficacy T2 66.37%, variable (R.N.F) greater expression T3 49.42%. Conclusions. The radical biostimulant influenced the height of the mother plant, the diameter of the pseudostem, the level of chlorophyll and the height of the son, the Aeration in the form of carving was positively distinguished.
