A field experiment was carried out during at two wheat growing seasons of 2020/21 and 2021/22 on Sakha Agricultural Research farm, middle north of Nile Delta to find out the impact of water deficit on five bread wheat cultivars; Misr 2, Sakha 95, Misr 3, Giza 171 and Shandaweel 1, with three treatments irrigation were; A-irrigating with 60% water needs (WN), B-irrigating with 80%of WN and C-irrigating with 100% of WN. The obtained results showed that irrigating with 100% of WN recorded the highest values of heading, and maturity days, biological, grain and straw yield and yield components. Sakha 95 has the highest grain yield, Sakha 95 and Giza 171 had the highest values of 1000 grain weight and number of grains/spike, while Misr 2 and Giza 171 has the highest values of biological yield. Irrigating wheat with 80% of WN has so many advantages; high yield as the full irrigation and saving water. Crop-water function of PIW and WP increased with water deficit.
