摘要：
An experiment was carried Out in Tres Pontas County, Minas Gerais State, Brazil to evaluate the influence of planting times and zinc doses on yield of crisphead lettuce (Lactuca saliva L.), cv. Raider. The trial was a split-plot arranged as randomized complete block design with four replications. The main plots (winter and autumn season) constituted the growing season and, the zinc doses (0.0; 0.18; 0.36; 0.54 and 0.72 kg/ha) were the subplot factors. The highest values of total and commercial fresh mass and, head circumference were obtained in the winter season and, of stern length in the autumn season. The highest yields of total and commercial fresh mass and, of maximum head circumference were verified using zinc doses of 0.45; 0.49 and 0.44 kg/ha. The zinc doses did not influence the stein length.
