The experiment was carried out at Fazenda Pirapitinga, located in the city of Canápolis, MG, Brazil. The objective was to evaluate the development of lettuce, purple and purple varieties under different types of coverings. The experimental design was (DBC), in a 3x2 factorial scheme, being: 3 soil openings (uncovered soil, Brachiaria mulch cover and mulching) and 2 varieties (var. Crespa and var. Roxa), with 4 replications. Plant height, leaf number and plant diameter were evaluated at 32 and 47 days after planting. It was concluded that the cultivar curled had a larger number of leaves and the lettuce cultivars had inferior performance in the plastic mulching.
