Three experiments were conducted in Santa Maria and Constantina - Rio Grande do Sul State - Brazil, to determine the effect of plant population on disease occurrence in common bean (type II grown) in the first and second growing season and to determine the most appropriate plant population. The experiment was established as a split-plot randomized block design with five replications. The results showed that there was no effect of plant population in disease incidence. The high plant populations provided higher or similar grain yield compared with the grain yield of the low plant populations.
