The aimed to evaluate the influence of different glyphosate formulations in nodulation, agronomic performance and RR soybean seeds yield, grown in two sowing periods. The experimental design was the casualized blocks with treats disposed in four replicates, being organized in factorial scheme, two seeding periods x five glyphosate formulations. The measured characters were number of nodules per plant, number of active nodules, number of inactive nodules, height of the first legume insertion, plant height, number of legumes per plant, number of seeds per plant, mass of thousand seeds and yield of seeds per plant. The isopropylamine salt influences nodular activity, number of vegetables and seeds per plant, as well as seed yield. The sowing of soybeans at the recommended time propitiates smaller modifications face to glyphosate formulations. mulations.
