Effect of El Niño 1997/1998 on N contents in frond 17 according to N fertilizer treatment in trial TT02 (N0: 0; N1: 60 and N2: 150 kg N ha−1 yr−1). The model curve refers to the influence of age on optimum content: N = 3.192–0.059 Age + 0.001 Age2. Average N contents increased from 87% in 1996 to 102% of the model in 1998. Vertical lines represent the standard error.

Effet de El Niño 1997/1998 sur les teneurs en N des feuilles 17 en fonction des apports de N dans l’essai TT02 (N0: 0; N1: 60 et N2: 150 kg N ha−1 an−1). La courbe modèle correspond à l’influence de l’âge sur la teneur optimale: N = 3.192–0.059 Age + 0.001 Age2. Les teneurs moyennes en N ont augmenté de 87 % en 1996 à 102 % du modèle en 1998. Les lignes verticales représentent l’erreur standard.
