The use of leaf fertilization aims to complement soil nutrition and to provide nutrients to the plant at specific times of great need. In addition to the complementation of nutrition, the use of plant regulators has the objective of greater expression in the development of crops, being used to increase productivity and quality in the plants. The experiment was realized using six treatments arranged in a block design (DBC), with four repetitions, totalizing twenty-four plots and aiming to evaluate the effect of complex nutrient containing sulfur, phosphorus, nitrogen, boron, copper, manganese, molybdenum, zinc, cobalt and plant regulators containing auxin, cytokinin and gibberellin applied in foliar spray at different vegetative and reproductive stages of the soybean crop (Glycine max L. Merril), cv. TMG 4190, being evaluated the parameters of treatment of productivity. It was evaluate the height of plants, height of insertion of the first pod, number of pods per plant, number of grains per pod, productivity and mass of 100 grains. In none of the results obtained was statistical difference between the treatments.
