- Abstract
In the Brazilian Northeast, lettuce cultivation is restricted to small areas, with the use of cultivars not adapted to the climatic conditions of the region, promoting early flowering and low productivity. Therefore, the objective of the research was to evaluate the agronomic responses of lettuce cultivars according to the age of harvest when cultivated in semi-arid conditions. The experiment was conducted in field between October 2013 and January 2014, in Mossoró-RN, Brazil. The experimental design was in randomized blocks, arranged in subdivided plots, with four replications. The plots consisted of five harvest ages (20, 25, 30, 35 and 40 days after transplanting - DAT), while the subplots corresponded to six lettuce cultivars of the groups: Leaf Smooth (Babá de Verão, Lívia and Aurélia) and Leaf Curly (Jullie, Elba and Maravilha 4 Estações). The following characteristics were evaluated: height and diameter of plants, number of leaves per plant, total and commercial yields, and shoot dry mass. The cultivar Babá de Verão is the most productive among the lettuce cultivars of the group Leaf Smooth and Jullie among the Leaf Curly. The lettuce cultivar Aurélia, from the group Leaf Smooth, is the less productive in relation to the others studied. The ideal harvest age at maximum commercial yield is 30 DAT for all lettuce cultivars.
