| An experiment was performed for two seasons to test the impact of water stress and drip irrigation lateral arrangements on yield and water productivity of the sunflower crop (seed and oil). Water stress treatments were Full crop evapotranspiration 100% ETc (FI100), 80% ETc (DI80), 60%ETc (DI60) and 100-60 % ETc (DI100-60). The DI100-60 treatment was applied as 100 % ETc up to seed formation then reduced to 60% ETc. The drip irrigation lateral arrangements were single planting row per one drip line with 2 L h-1 drippers (T1) and double planting rows per one drip line with 4 L h-1 drippers (T2). Results revealed that applying water stress by either DI80 or DI100-60 produced almost the same or more yield of sunflower seeds and oil than that obtained from full... |
