Abstract

This study was conducted in order to determine the effect of DEFICIT IRRIGATION on yield and water use efficiency of new clones of potato. The study was conducted in Agriculture and Natural Resources Research Center of Hamedan Province in split plot design based on Randomized Complete Block with three replications. The main factor consisted of 6 irrigation treatments: 50, 60, 70, 80, 90 and 100 percent of crop water requirements. The sub-plots consisted of four POTATO CLONEs and the control cultivar Sante. Water was applied by drip irrigation (tape). Measurements included water use efficiency in different irrigation treatments, total yield, tubers size, deformed tubers, decayed tubers, marketable yield and dry matter of the tubers. Results of multiple analysis variances of two years of experiment demonstrated that the effect of water treatment and clone was significantly different at 1% level in total traits, including the number and average yield of large tubers, seed tubers, and small tubers as well as total yield and water use efficiency. Maximum yield belonged to clone 397008-2 (72.7 Ton/ha). though it was not significantly different in 80, 90 and 100% IRRIGATION REGIMEs. In most water treatment, clone 397008-2 had the highest yield, although a significant difference between this clone and clones 397007-9 and 3970015-13 was not observed. Also, this clone had the highest WUE in irrigation treatment supplying 80% of potato water requirement. The highest percentage of tuber dry matter was achieved in the 60% irrigation treatment (22.87 %), which was significantly different (at 1% level) than the 50, 70 and 80% irrigation treatments. Overall, the maximum WUE belonged to the 80% irrigation treatment, being significantly different (at 5 percent level) than the other treatments. The results showed that provision of 80 percent of water requirement, in addition to saving water compared with the 90 and 100 % treatments, increased the water use efficiency significantly. Clone 397008-2 was better adapted to DEFICIT IRRIGATION than the other clones. Therefore, planting of this clone is recommended in areas faced with water shortages.
