With the new considerations proposed,
the treatments with the optimum N dose obtained a total water footprint between 127.8 and 151.7 m3t−1.Higher values than those were presented in the treatments with the least N dose (145.7 and 158.4 m3t−1),
although the highest values of water footprint were obtained in treatments with a N excess (226.0 and355.0 m3t−1).
