The present study was carried out to ascertain, the optimal seeding rate of 40, 50, and 60 kg/fed for six promising bread wheat cultivars: Giza 171, Misr 3, Misr 4, Sakha 95, Nubaria 2, and Sids 14 based on yield-contributing traits. The research investigation was carried out at El-Gemmeiza Agricultural Research Station, Agricultural Research Center, Egypt, during seasons, of 2021/22, and 2022/23. The results showed that the highest grain yield was produced by the Misr 4, which outperformed Sakha 95, Misr 3, Giza 171, Sids 14 and Nubaria 2. The best seeding rate was 50 kg/fed. Regarding the interaction, the seed rate 50 kg/fed under Misr 4 cultivar produced the highest grain yield. However, Sakha 95 yielded the highest grain yield at the lowest seeding rates (40 kg/fed).
