Summary:When these, exceed 20 °C, plant bolting is induced early, causing depreciation of the final product (Santi et al., 2010). [...]production data of this vegetable in regions with high temperatures in most of the year, such as the Brazilian semi-arid, are incipient. Reporting, increments of up to 10 t.ha-1, when the thermo-reflective screen is compared with the full sun, under tropical conditions (Neves et al, 2016). [...]the production in protected environment can allow better performance of the Crisphead lettuce under conditions limiting its development, when compared to the crop in full sun. Primarily in regions with an intra-annual climatic variability, such as Submedia region of the Säo Francisco Valley. [...]studies should recommend cultivars that can produce satisfactorily throughout the year or specific genotypes to each climate condition during the year. Selection and development of cultivars and lettuce cultivation techniques appropriate to these areas will also reduce crop loss and improve economic opportunity for producers, especially family farmers. [...]the objective of this work was to evaluate the production of crisphead lettuce cultivars in two growing seasons, under different semi-protected environments, in the Submedia of the Säo Francisco Valley.
