ResumoMolybdenum is the micronutrient required in less quantity by plants and found in lower concentrations in Brazilian soils. The study aimed to study the influence of the application of molybdenum (Mo) and potassium (K) via foliar feeding, at different phenological stages, on the quality of soybean seeds. The work was conducted in the field in the county of Coronel Bicaco, RS under the condition of a typical dystropheric red Latosol (Oxisol) soil, in the 2017/2018 season crop. The experimental design was randomized blocks in a factorial scheme phenological stages x cultivars. Analysis of variance revealed significance for the interaction between phenological stages x cultivars for the variables composed by germination, abnormal, hard, dead, as well as field emergence, plant length and root length. There is influence of foliar feeding of molybdenum (Mo) and potassium (K) in different phenological stages of soybean. It was found that there was no significant difference for the yield of soybean cultivars under foliar feeding of Mo and K in the different treatments to which they were submitted.
