The aim of this research was to evaluate the deposition obtained with flat fan nozzle AXI 11002 and hollow cone JA-2 operated in two pressure and with and without air assistance in soybean crop. The flat fan nozzles at 300 and 400kPa and hollow cone at 400 and 600kPa, with and without air assistance were evaluated. The experimental design were randomized blocks and two repetitions in different times of the plants. The solution tracer was composed of Brilliant Blue (FDC-1) at 0.3%. The applications were executed by air assisted boom sprayer, Falcon Vortex Model. The results showed that the air assistance doesn’t influence on the total deposition in the plant, but it provided a better penetration and more deposition in the botton of the plants.
