Abstract

Lettuce is a crop with high commercial and social importance, reaching from the macro to the Brazilian micro producer. The objective of this study was to evaluate the agronomic performance of Elba and Rouge lettuce cultivars in terms of development and production, under different environments, for the edaphoclimatic conditions of Juazeiro, Bahia. The experimental design adopted was completely randomized, in a split plot scheme, with two production environments (shaded environment and full sun) in the plots, and two lettuce cultivars (Crespa, CV. 1 Elba and Roxa, CV. 2 Rouge) in the subplots. The variables analyzed were: plant height, plant diameter, average fresh weight, average dry weight, total productivity and water use efficiency. The cultivation system in a protected environment showed better development and high productivity for the two lettuce cultivars, when compared to the system in full sun. Cultivar 1 showed superior performance to cultivar 2, in all variables analyzed, in both cultivation systems.
