The objective of this work was to evaluate the effect of doses and time of Mo leaf application on yield and physiologic quality of seeds on irrigated common bean, cultivar Pérola, grown in Typic Quartzipsamment. A randomized complete block design was used, in a factorial array 4x2 with four replications. The treatments were constituted by four doses of Mo (0, 40, 80, and 160 g ha-1) and two application times: 15 or 26 day after emergence of seedlings. Molybdenum leaf application increased the seed yield and the shoot matter dry of seedlings of irrigated common bean, independently of the application time (15 or 26 DAE). Common bean seeds germination was increase by Mo leaf application at 26 day after emergence. Common bean seeds vigor, evaluated by first germination count, decreased with Mo leaf application. Molybdenum leaf application increased the common bean seeds yield and promoted of seeds that will originate seedlings with larger initial development.
