This study was investigated the effect of sowing dates ( 30 th April , 30 th May and 30 th June ) , irrigation requirements ( 50 %, 75 %, 100 % IR ), sunflower cultivars ( Sakha - 53 and Giza -102 ) and their interactions on sunflower growth, yield and its components . The results showed that plant growth and yield were increased with early sowing date ( 30 th of April). But delayed June 30 th planting date treatment achieved the highest averages of leaves proline content. Reduce water to 50 % IR treatment is not suitable for development sunflower and obtained high seed yield. Sakha-53 produced significantly higher plants vegetative growth and biological yield than Giza-102. Finally, data revealed that planting sunflower cv. Sakha-53 in end- April using 100 % IR followed by 75 % IR gave the highest values from plant growth, seeds-yield and yield components.
