The aim of this experiment was to evaluate the best track of a bar sprayer-set in three points of the tractor, in soybean and bean crops. Sprayings were oriented longitudinally to the sowing lines and transversally to the sowing lines with tires passing through pre-determined areas where the sowing was not done (tramlines). Yield factors were evaluated the factors related to yield. Results showed no difference in relation to the components of yield evaluated in the soybean crop even when a variation was done in the track of spraying. However in the bean crop there was a bigger production when track was sprayed longitudinally.
