Abstract
In 3 trials in 1967-9 near Cesena, Italy, 2 levels of N were applied in winter with or without foliar sprays of urea, at 15-20 days after flowering, to 3 varieties of durum wheat and S. Pastore of soft wheat. In comparison with 75 kg/ha, the higher rate of N (120 kg/ha) applied in winter increased grain yield in S. Pastore but not in the durum wheat cultivars. Urea sprays reduced yields slightly. Protein content of the grain was increased by winter N application and especially by urea sprays.
