Abstract
Effects of the last irrigation time on quantitative and qualitative traits were studied for two sugar beet cultivars with intermediate and long growth periods. This research was conducted in the field of Agricultural and Natural Resources Research Center of Khorasan at Mashhadin 1381. Six treatments of withholding irrigation were applied on the cultivars using a spilit plot design within a randomized complete block design with four replications. Irrigation treatments arranged in main plots were 60, 50, 40, 30, 20 and 10 days before harvest and varieties 7233 and PP22 were in sub plots. The results showed that irrigation treatments had significant effects on the root yield, sugar content, white sugar content, Na, K, molas sugar, net and gross sugar content, while cultivars effects (except K) and irrigation×cultivar interactions were not significant either for root yield or other traits. In this experiment, net sugar content increased with shorter irrigation period before harvest. However,Duncan's test showed that there were no significant difference between irrigation treatments from 40 to 10 days before harvest. It was found that the 20-days-irrigation prior harvest provieded maximum gross income and an economized water use.
