The field experiments were conducted in El-Mattana Agricultural Research Station, Luxor, Governorate during the two successive seasons (summer season 2020 and summer season 2021) to investigate the effect of irrigation intervals (every 7, 15, and 21 days) and two planting methods (ridge planting and raised bed planting) on the yield of two varieties of sunflower in Upper Egypt, namely: (Sakha 53 and Giza 120 varieties) The experimental design was Split-Split Blocks Design (Stripes) under (RCBD) and included four replications and three factors, the first of which was irrigation intervals, which were placed in whole plots, the second of which was planting methods, which were placed in subplots, and the third of which was varieties, which were placed in the sub-sub plot. The results cleared that irrigation intervals produced a significant effect on all studied traits in both seasons. The results showed that irrigation intervals had a significant effect on all studied traits in both seasons. Irrigation every 7 days produced the highest mean values of plant height (cm), seed weight head (g), and seed yield (kg/fed -1) in both seasons, while irrigation every 15 days produced the highest mean value of and oil yield (kg/fed). While irrigation every 21 days produced the highest mean values of oil percentage% and 50% flowering date .
