The objectives of this work was to evaluate the effects of nitrogen and phosphorus doses on weeds management in baby corn crop yield. The experiment was conducted under field conditions. The experiment followed a factorial 2 x 3 x 5 scheme, in which factors and levels were the following: phosphorus doses, weeds management and nitrogen doses. A fully randomized block design, with four replications, was used. There were larger growth of corn plants and accentuated reduction of the infestation and growth of weeds in response to the increasing of N doses. There was also increase in commercial ears (PEC) with the increase in the N doses.
