dc.descriptionhe release of wheat cultiv ars with different nutritional demands and yield potential hinders generalized recommendations for nitrogen fert ilization. This study was designed to evaluate the effects of different nitrogen fertilization levels (0, 60, 120 and 180 kg ha -1 of N) on the agronomic performance of six wheat cultivars ( Triticum aestivum L.) in two harvests. A randomized block factorial design with three replications was used. The response to fertilization levels was evaluated through AMMI (Additive Main effects and Multiplicative Interaction) and GGE (Genotype main effects and Genotype x Environment interaction) biplot graphic methodologies and polynomial regression. There was genetic variability in response to nitrogen fertilization in th e cultivars studied. The biggest increases in yield were observed under a more suitable water regime. The high er performance of yield components was associated with higher nitrogen fertilization levels.
