%X this paper has as main goal the evaluation of lhe effect of nitrogen application on the yield of no tillage com crop, planted over black oats. experiments were conducted m the agricultural year of 1996/97 in three experimental units of the abc foundation located in the campos gerais region of the state of paran¨¢. the experimental design was a split-plot randomized block, being the plot treatments the two doses of n applied to the oats crop (o and 30kg h¨¢-1 in the planting time) as the main plots and as the time of application of n in the com crop (no nitrogen; 30kg h¨¢-1 in the planting plus 90kg h¨¢-1 broadcasting in the 6a leaf time; 90kg h¨¢-1 during the oats crop management plus 30kg h¨¢-1 in the com planting; and 120kg h¨¢-1 during the oats crop management plus 30kg h¨¢-1 in the com planting) as split plot treatments. it was verified the oats crop fertilization dia not influenced com yield. the com yield was not affected by anticipated n application usually used in corn's broadcasting.
