Aiming to evaluate the effect of irrigation depth and soil moisture uniformity on dry bean yield, an experiment was conducted with the cultivar IAPAR 57. Water was applied on soil surface at four uniformity levels with the same irrigation depth, imposed by four sprinklers spaced at 12 x 12 m; 18 x 18 m; 18 x 24 m, and 24 x 24 m. Spatial distribution analyses of the irrigation depth, soil moisture and grain yield data were proceeded with exploratory data analysis techniques based on simplified box-plot graphics, which only represent the median, minimal, and maximal values. It was verified that the quality of irrigation affected the soil moisture uniformity, causing effect also on dry bean yield. The maximum uniformity of water distribution did not relate with the highest yield.
