The experiment was conducted in a hay production field at the State University of West Paraná, planted in 2004 with Cynodon spp.
cv.
Tifton 85.
The experiment was established in a randomized block design with factorial treatments of five N fertilization amounts (0, 25, 50, 75 and 100 kg ha-1 cut-1) applied as urea after each cut, and two regrowth intervals (28 and 35 d), with four replicates.
N application promoted changes in plant structure, such as increased canopy height, stem length, leaf elongation rate, and dry mass (DM) production.
