Adaptación de dos variedades de arándano (Vaccinium corymbosum), Biloxi y Emerald, bajo cubierta y semicubierta en el Centro de Investigación e Innovacción Tecnológica Agropecuaria Tungurahua - Pillaro (CIITAT).

Abstract

This research project was developed at the Center for Agricultural Technological Research and Innovation Tungurahua - Píllaro (CIITAT) in order to determine the adaptation of two varieties of blueberry (Vaccinium corymbosum), Biloxi and Emerald, when exposed to different climatic conditions. , the treatments with which we worked were T1 under plastic cover, T2 semi-covered, plastic and saran and T3 control in the open field, the study factors that were analyzed were plant height, number of shoots, number of flowers per cluster and number of fruits per bunch. It is worth mentioning that for all the treatments the substrate used was the same, as well as the fertilization, pH correction and irrigation. The data was taken monthly after the transplant until 6 months later. An experimental randomized block design with a 22+ 2 factorial arrangements with three replications was used. For the sources that were significant, the 5% Tukey test was used for the comparison of means. The results indicate that the Biloxi variety, when protected under cover, forming a controlled microclimate, presented better adaptability, fertilization and, consequently, a higher production level. In conclusion, the Biloxi and Emerald varieties show greater adaptation capacity in the T1 under cover. The investment for a blueberry crop under cover is high, but the life cycle of the blueberry allows us to recover it in the short term.
