The combined data from two growing seasons in a field experiment study by using two irrigation systems (surface and subsurface drip) in terms of additional water for sugar beet plants under saline conditions are used to estimate root and sugar yield, water use efficiency and root penetration power at the time of harvest. Water salinity levels of 6000 and 8000 ppm were applied to irrigate sugar beet from the time of planting on October 3 to the time of harvest on April 22 with three additions of water (limited 1750, moderate 2500 and optimum 3250 m³/fed). The results are summarized as follows: The heaviest root and highest sugar yield as well as highest water use efficiency were recorded when using subsurface irrigation system, 6000 ppm water salinity level, and moderate or optimum irrigation water (2500 or 3250 m³/fed). Oppositely, the highest penetration power values were obtained using drip irrigation systems with low water quantity (1750 m³/fed) and high-water salinity level (8000 ppm).
