BACKGROUND There are many scientific studies on performance of different sweet potato varieties under water deficits, however, no study on Koganesengan and Beniazuma varieties has been found in the literature. This study was aimed to investigate the effects of water deficit levels (control-WD0, low-WD25, medium-WD50 and high-WD75 water deficit levels) on growth, yield and quality parameters, water use efficiency and water-yield response factor values of these sweet potato varieties under drip irrigation.
