In the production of vegetables, one of the important factors in their production is the cultivation environment, which influences productivity, including varieties and growing seasons. The objective of this work was to evaluate the production, leaf temperature and soil temperature of two lettuce varieties (smooth green and crisp purple) as a function of environmental variables in two environments (field and greenhouse). The design used was completely randomized in a 2 x 2 factorial scheme (2 varieties and 2 environments), with six replications. Where, from the thermographic images, similarity was registered regarding the soil temperature between the environments, not interfering with the performance of the roots of the cultivated varieties, whereas the leaf temperature was higher for the purple curly variety. It was found that a greenhouse provided the best conditions for the development of the lettuce varieties, observing, in both environments, the best performance of the smooth green variety lettuce.
