Evaluación de dos variedades de sandia (Citrullus lanatus L.) en invernadero bajo nivel (walipini), durante su etapa vegetativa en la comunidad Palacio Real, Chimborazo

Abstract

The aim of this research was to evaluate two varieties of watermelon (Citrullus lanatus L) in greenhouses under Walipini level during their vegetative stage in the community of Palacio Real. The methodology implemented consisted on a study both in open field and in greenhouse under Walipini level with the following indicators: average temperature in degrees Celsius of the soil surface and environment, germination percentage, number of surviving plants at 60 days, plant height, number of leaves, number of branches and stem diameter. These data were taken at 15,30,45,60 days after transplanting. The study was carried out in a completely randomized block experimental design (CRAB) with a bifactorial arrangement with 3 replications, in 2 environments (open field and walipini) and two varieties (Charleston Gray and Quetsaly). Through this methodology it was determined that the best treatment was the Charleston Gray variety planted inside the walipini, since it presented the best agronomic performance as a greater diameter of the stem (0.9 mm), greater number of flowers (16.26 flowers) and finally a greater number of secondary branches (3.37). On the other hand, it was observed that the least favorable treatment was the Quetzali variety, which did not stand out in its physiological characteristics compared to the Charleston Gray variety. In this context, it is concluded that the watermelon variety Charleston Gray is the indicated variety to be cultivated in greenhouses under walipini level, as an alternative to supply the national demand, due to its excellent agronomic behavior and acclimatization.
