The yield of lettuce plants cultivated under agrotextile protection was evaluated in conditions of high temperatures and intensity of radiation. The experiment was carried out at the experimental area of the Universidade Federal Rural do Semi-Árido, in Mossoró, Rio Grande do Norte State, Brazil, in a red-yellow argissol. The randomized complete blocks design was used, with four replications, in a 3 x 3 factorial scheme. The treatments consisted of the combination of three lettuce cultivars (Tainá, Babá de Verão and Verônica) with three types of plant protection (non-protected, direct-on-the-plant agrotextile protection, and nonwoven polypropylene tunnel with height of 0.5 m). The best yield performance was observed when the lettuce cultivars were grown in low tunnel.
