The monitoramento of variáves of growth, height of the plant and diameter of I collect it, after initiated 15 days the emergency of 50% plus one plântula until the 90 days of the changes. The results gotten in the end of the experiment, 90 days, were of 10.92 and 7.50 cm for height of the changes watered with water of the supplying and treated water, respectively.
