The strawberry (Fragaria vesca) is a crop of great acceptance worldwide. In Ecuador, most of the production is done in open field, presenting limitations by the attack of biotic factors and abiotic factors that generate losses in the production. This research was carried out in the province of Loja, since there was no precise information on this crop, and research on the use of protected systems (low tunnels). The main objective of the study was to evaluate the effect of strawberry production on the two production systems (open field and low tunnels), with Albion and Monterey varieties, as well as to analyze the costs and profitability of production. The experiment was conducted at the Agricultural Station of Universidad Técnica Particular de Loja, under low tunnels and open field conditions, in which the phenological and productive development of the strawberry was compared. The results found in the study in the two open field and low tunnel systems did not present a statistical difference in the physiological variables evaluated, which allow to conclude that the low tunnel cover on the crop did not influence the development of the two varieties. In relation to the cost-benefit analysis of production, it was higher in the low tunnel system, the investment was stronger at the beginning, but it must be indicated that there are several productive advantages in relation to the open field that generate benefits for the strawberry producer.

Keywords : Low tunnels.
