Evaluación de sustratos para la producción de arándano (Vaccinium corymbosum L) cvs. Biloxi y Emerald bajo condiciones de invernadero en la Granja el Romeral, Guachapala-Azuay

Abstract

At present, the blueberry is a crop of great importance due to its nutraceutical properties, presenting a superficial root system, for this reason it is currently being produced in substrates which help in the efficiency of this crop. The objective of this research was to evaluate substrates for the production of blueberry (Vaccinium corymbosum L) cvs. Biloxi and Emerald under greenhouse conditions at Granja el Romeral, Guachapala-Azuay. Independent experiments were performed for cvs. Biloxi and Emerald, with a completely randomized experimental design, with 5 treatments and 6 repetitions: Coconut fiber + c.a., Palm fiber + c.a., Cypress sawdust + c.a., Pine sawdust + c.a., Pine leaf + c.a. The results obtained in cv. Biloxi for the variables stem diameter, number of flowers, volume, length, dry and fresh weight of the root system, the best average was obtained based on the substrate Palm fiber + c.a. after seven months of investigation. For the variables Plant height and number of leaves, the best averages were obtained based on the substrates Pine leaf + c.a. and Pine sawdust + c.a. In the cv. Emerald for the variables height of the plant, number of leaves, volume, dry and fresh weight of the root system, the best averages were obtained based on the substrate Palm fiber + c.a. For the variables stem diameter and length of the root system, it was not obtained significant results.
