Evaluación del efecto de la aplicación del agua de mar como solución nutritiva en el cultivo de banano.

Abstract

The cultivation of banana (Musa x paradisiaca, L) requires an appropriate amount of macroelements and microelements, because they are essential in each of the phenological stages of this crop. However, an excessive application of any of the macros and micronutrients can be contradictory to the functioning of the plant. The objective of the research was to evaluate the effect of applying seawater as a nutrient solution on banana cultivation. The present investigation was carried out on the "Santa Inés" farm, located in the Faculty of Agricultural Sciences of the Technical University of Machala, 5.5 km from the Machala - Pasaje road, El Cambio parish, Machala canton, province of El Oro. The experimental design used was a randomized block design, implemented in the banana experimentation area of the “Santa Inés” Farm, seawater and fresh water were used, which were mixed in treatment 2 and treatment 3. Using different dosages, 10 treatments were obtained, including the control. The treatments were applied in an area of 700 m2, each dose was placed on 5 plants respectively. The variables evaluated were: plant height, stem, leaf area, leaf emission, root sampling, electrical conductivity and hydrogen potential (pH), for which plants that have similar characteristics should have been used. It was determined that the incorporation of 50 CC of seawater exposed to the sun (AMPS) for the development variables. However, a higher performance was observed in the root variables with the dose of 50 CC of AMPS 1/30, so it can be highlighted that the application of any of these treatments is beneficial depending on the producer's needs.The cultivation of banana (Musa x paradisiaca, L) requires an appropriate amount of macroelements and microelements, because they are essential in each of the phenological stages of this crop.
