To evaluate the effects of planting dates and four cloves classes of garlic (Allium sativum L), cultivar Quiteria, one experiment was conducted. The experiment was located in the county of Rio Grande, RS, Brazil. The experimental design was a randomized complete block with four replications and the treatments formed a factorial in split-plot where planting dates formed main plots and clove classes the sub-plots. Significant effects were observed for planting dates, clove class as well as interaction among tratments. Greater bulb yields were observed in the three last planting dates (08/10/87, 08/21/87 and 09/08/87) depending on the clove class used. Within each planting date the effect of class clove was observed. There was significant effects within planting dates and greater yields were observed in classes 1 and 2 (average weight 4.87 and 3.03, respectively).
