Evaluación de cuatro variedades de frutilla (Fragaria x ananassa Duch) en dos sistemas semi hidropónicos.

Abstract

This investigation aimed to evaluate four varieties of strawberry (Fragaria x ananassa Duch) in two semi-hydroponic systems which was carried out at the Experimental Irrigation Center (CER), ESPOCH using a bifactorial randomized complete block design (RCBD) with four replications per treatment. The height of 10 randomly selected plants per treatment was evaluated 30, 60 and 90 days after transplanting. The harvests were carried out for a period of 14 weeks and in each harvest the fruit was classified according to the commercialization categories in the municipal market in Riobamba. In addition, 5 ripe fruits were selected from each treatment to evaluate the percentage of accumulation of soluble solids by using a manual refractometer. The economic analysis was carried out using the benefit/cost ratio, considering the total income and costs of each treatment. For days to flowering, Cabrillo and Albión varieties reached this phenological stage in the shortest time with an average of 63 and 64 days after transplanting. The highest total production was obtained by San Andreas variety with an accumulated 611.23 grams of fruit per plant. This variety in open channel obtained the highest profit/cost ratio with 2.78 dollars, which corresponds to a profitability of 178%. For cultivation in semi-hydroponics, San Andreas variety in open channel is recommended because it obtained the highest production, benefit/cost ratio and profitability.
