Research has been undertaken in order to identify the best management of application of manganese and zinc for soybean in more different types of regions. However, there is still no agreement on the results, because the dynamics of these nutrients in the soil is also influenced by the mode of application. The objective of this study is to evaluate the influence of different modes of application of manganese and zinc in soybean. The experiment will be conducted in the experimental area of the Federal Institute of Science and Technology of Mato Grosso - Campus of Parecis (IFMT). The experimental design is a randomized block and will be used two soybean cultivars, being a transgenic (TMG 1149 RR) and a conventional (TMG 4190), in 10 (ten) treatments with different modes of application of manganese and zinc, with four replications , totalizing 72 plots of 20 m2 each. The sources of manganese and zinc are manganese sulphate and zinc sulphate, respectively, with recommendation to 5 kg ha-1, when applied to the soil, and 0.5% solution of the product when applied foliarly. Soybean cultivars will sown in the conventional spaced 0.45 m between lines, aiming at a final population of 15 plants per meter of row, with a density of 330,000 plants ha-1. Will be measured nutritional characteristics of culture, morphological and productive. Keywords: Glycine max L. Merrill, micronutrient, manganese deficiency.
