Field experiments were conducted during 2001-03 in Poland to determine the possible use of saline water for supplemental irrigation of vegetables, i.e. red beet [beetroots]. On the average, supplemental irrigation caused yield increase of 43% compared with the unwatered control. Tap water (salt contents at 200 mg/dm3) increased the yield of red beet by 62% while diluted saline water (salt content at 2700 mg/dm3) caused a 45% yield increase, and saline water (salt content at 5200 mg/dm3) increased the yield by 23%. Supplemental irrigation significantly increased photosynthesis, transpiration and stomatal conductance. The best results (increased physiological activity) were observed in plants irrigated with tap water. The net productivity of 1 mm water used for irrigation depended on the salt content in the water, and was best for tap water. These effects were of a lesser extent when the irrigation water contained more salt.
