Providing the sugar beet water requirement with modern irrigation methods as sprinkler, micro and subsurface irrigation methods are very important because of it,s high water requirement and long growth period.The aim of this study was to investigate the possibility decreasing in water application in trickle irrigation and effects of trickle irrigation on qualitiy and quantity parameters of sugar beet and to compare water consumption and water use efficiency.The experiment (C.R.B.D) was conducted at Ekbatan Research Station in Hamedan with 3 replicates. Treatments were :(1) Trickle (Tape) irrigation with water consumption equal of evaporation replishment 100%,(2) Trickle irrigation with water consumption equal of evaporation replishment 75%,(3)Trickle irrigation with water consumption equal of evaporation replishment 50%.The results showed that amoung of irrigation treatments in respect of sugar content,white sugar content, exractability ,sugar yield and white sugar yield haven,t significant difference(ل=5%).The maximum and minimum of water use efficiency related to sugar yield to be connected Tape(50%) and Tape(100 %) with 905(gr/m3) and 699(gr/m3) respectively.The comperation of Tape(75%) and Tape(100%) irrigation showed that water consumption was decreased about 18 percent and water use efficiency was increased about 27.6 percent in Tape(75 %) treatment.
