Brazil is the largest beans producer, and this legume is one of the primary sources of plant-based proteins. Some minerals, such asmanganese, are essential for this crop development. From the socio-economic importance of the beans crop, this study aims to evaluate theagronomic performance of irrigated common beans grown under different doses of manganese on two application periods. The experiment was conducted in the experimental area of the Instituto Federal Goiano, Campus Ceres (GO), adopting an experimental design arranged in a 2x4 factorial scheme with four replications, comprising two periods of application (V4 and R5 phenological stages) and four Mn doses (0, 150, 300, 450 g ha-1). The variables evaluated were plant height (m), number of pods per plant (NPP), number of grains per pod, 1000-grain weight (g), and yield (kg ha-1). The dose of 450 g ha-1 of Mn provided the highest yield regardless of the application period.  The higher NPP was obtained with the dose of 150 g ha-1 in V4. Also, the dose of 450 g ha-1 of Mn in V4 provided the most significant 1000-grain weight.
