Abstract

SUMMARY The vulnerability of Guatemalan families to food and nutritional insecurity is a problem that has worsened due to the crisis of the 2019 coronavirus pandemic (COVID-19); Faced with this adverse circumstance, Aldea Chocolá is no exception. Under this context, the adaptability of two cultivars of Brassica oleracea L., broccoli and cauliflower, has been evaluated, focused on field production and rations for people in two strata of Chocolá, San Pablo Jocopilas, Suchitepéquez. With this research, positive results have been generated towards strengthening the productive system of said village, expanding the diversity of species in family gardens, which allows its inhabitants to grow, harvest and consume local and highland vegetables, thus strengthening food and nutritional security. Geographically, the Chocolá Village is divided into two strata (high and low). The high stratum corresponds to the very humid tropical premontane forest and the temperature conditions oscillate between 18 and 24°C; Specifically, the plot where the investigation was carried out, is located at an altitude of 788 meters above sea level and is located at a latitude of 14.61384 N and a longitude of -91.41975 O. The lower stratum is made up of very humid tropical forest, which has temperatures between 24 and 26.7 °C; The plot in which this study took place is located at an altitude of 556 masl and is located at a latitude of 14.57352 N and a longitude of -91.41799 O. In the upper stratum, it has already been proven that broccoli and cauliflower can effectively be produced. Therefore, to determine if both vegetables can also be produced in the lower stratum, two simple experiments were established under the complete randomized block design and arranged in a group of experiments by geographical sectors. The results obtained indicate that partially in the lower stratum, cauliflower production (2,246.31 kg/ha) is possible, since it produces lowquality inflorescences, but in acceptable terms for family consumption; In the case of broccoli, it was found that its production is not possible, since although it produced 2,182.92 kg/ha, the inflorescences turned out to be of very poor quality (malformed and unstable).
