This research aimed to evaluate the influence of some variables the infiltration of water into the soil in an area of tobacco growing (Nicotiana tabacun) in Mallet county / PR. Between variables evaluated are: soil management, rain, soil cover and compaction. The handling of this culture can be performed in areas, which show some restrictions to mechanization for being cultivated by conventional manners. The infiltration of water into the soil was carried out monthly during the period of cultivation of tobacco (September to March), and for this, a manual infiltrometer with cylindrical rings. The average infiltration in the lines along the cultivation was of 25.6 mm / h, while in the ridges was of 40.9 mm / h. This variation may be linked to the soil tillage in both areas, besides the tobacco plant morphology influence which increases soil coverage in the ridges end soil compaction.
