In Colombia, strawberry crops are mostly established in open fields, which have some limitations related to pests and diseases, such as Botrytis cinerea and Sphaerotheca macularis, which can generate significant production losses, as well as other factors related to exposure to adverse weather conditions. High tunnel technology for this crop has been implemented to counteract these effects; therefore, the objective of this study was to characterize the production cost variable associated with the cultivation of strawberries, making comparisons between two environmental conditions: open field and high tunnel, in order to determine the feasibility of implementing this technology. This experiment was conducted on the New Granada Campus of the Universidad Militar, located in Cajicá (Cundinamarca, Colombia), in a 403 m² area arranged in three high tunnels (HT) and an open field (OF), with 1,620 plants. To record the costs, a field record book was used which was filled out daily and in chronological order for 56 weeks. The obtained results indicate that it is advisable for producers to invest in HT as its cost is low and it has a long shelf-life, especially if you consider that the losses caused by B. cinerea are higher with OF than with HT and that this disease represents a higher cost in terms of handling as compared to other diseases and pests.
