Treatments Durum wheat: Four commercially released varieties CaparoiA, DBA AuroraA, DBA LillaroiA and JandaroiA, and an advanced breeder’s line from the Northern Durum breeding program 190873 in a fully replicated, factorial design with six N treatments in total. Nitrogen (N) rate: 0, 40, 80, 120 kg N/ha and two split applications 2 × 40 kg N/ha either at sowing and GS31 or at sowing and GS39, all applied as urea (46% N). All treatments were side banded at sowing, apart from the split applications, which had half applied at planting and half at stem elongation (GS31) or at flag leaf emergence (GS39) (total 80 kg N/ha). Sowing date: 19 May and 9 July, in a split plot design with three replicates.
