A field trial was performed in 2000/01 and 2001/02 in the experimental farm “Sparacia” (Cammarata – AG – Sicily) in order to evaluate the qualitative and quantitative response of four varieties of durum wheat when grown after a legume crop (field pea) or in rotation with itself and when submitted to different N-fertilization levels: no fertilization (N0, control), 60 kg ha-1 (N 60, rate advised by the EC n. 2078/92 for the Sicilian territory) and 120 kg ha-1 (N 120, fertilization rate commonly used under the “traditional” cropping technique). In the first trial year, the fertilized trial expressed a better yield performance than the control, but in 2001/02, characterized by severe and prolonged dry periods, the effect of crop rotation and variety was shown to be more important.
