The drip irrigation system is designed to irrigate two crop rows with one lateral line. Coyote cultivar (Beta vulgaris var. Coyote) was used in the randomized split block experimental design with three replications. Evaporation from Class A Pan has been used for determining the amount of irrigation water. The treatments were irrigation intervals (4-8-12 days) and the rates of the accumulated Class A Pan evaporation (K1=1.25, K2=1.00, K3=0.75 and K4= 0.50). According to our results, the amount of irrigation water in the treatments ranged from 279 mm to 668 mm, water consumption amounts between 520 mm and 827 mm sugar content from 17.51% to 15.35%, K amounts between 2.09 and 2.84 with Na amount of 0.71 αN amounts between 1.29 and 1.59 to 2.76. Our statistical evaluations indicated that different irrigation programs have a significant effect (p<0.01) on the quality of sugar beet.
