Three genetically different, high yielding winter wheat cultivars (Zhitnica, Novosadska Rana 2 and Jugoslavija) were evaluated at Zrenjanin in Yugoslavia on a fertile saline marsh soil from 1981/82 to 1984/85. Seed was sown during the first, second and third 10-day periods of October and November. Nitrogen fertilizer was added at 80, 120 and 160 kg/ha. The results showed that Zhitnica was the most tolerant of salinity, while Novosadska Rana 2 was the most sensitive. Optimal sowing dates were 1-10 October for Zhitnica and Jugoslavija, and 15-25 October for Novosadska Rana 2. Yields of 5-7 t/ha were obtained using 120 kg/ha. The trials showed that increasing fertilizer rate did not prevent the decrease in yields associated with late sowing.
