The objective of this study was to evaluate the physiological quality and productivity of soybean seeds produced from seeds enriched with molybdenum in two consecutive years. In the first year, the seeds of three cultivars, CD-206, MSoy-7101 and BRS-183, were enriched with two foliar applications of 400 g.ha-1 of Mo, in stages R3 and R5. Evaluations were made of the yield, thousand seed weight and molybdenum content. The germination and vigor for accelerated ageing were evaluated at zero and after six months storage. In the second year, the cultivars CD-206 and BRS-183, produced from the seeds enriched with Mo the previous year, were treated with Mo at a dosage of 20 g.ha-1. Evaluations were made of the yield, thousand seed weight, molybdenum concentration and germination and vigor by accelerated ageing. The seed produced by applying molybdenum at high dosages during the R3 and R5 stages showed high levels of the nutrient but did not transfer the same concentration of nutrients to the next seed generation. This enrichment and application via the seeds did not affect the physiological quality of the seed produced or the productivity under the conditions of the study.
