A study was conducted to investigate the effect different methods of furrow irrigation and plant densities on quantity and quality of sugar beet yield in Aleshter city in planting year of 2010 in RCBD (split plot) design with four replications. Main plots included three levels, a1= single rows 50cm apart; all furrows irrigated, a2= single rows 50cm apart; alternate furrow irrigated and a3= double rows 75cm apart; all furrows irrigated. Sub plot include three density levels (b1=100,000, b2=80,000 and b3= 66666 plants/ hectare). Each plot has four rows with length of 40 m. Results showed that there is significant difference between main plot and sub plots in root yield, water consumption, sugar content, WUE on the basis of root yield, WUE on the basis of sugar yield, impurities potassium and highest WUE on the basis of sugar yield was obtained in treatment a3b1 for 1.496 kg/m3with sugar yield with 11.240 ton. ha-1. Therefore the treatment a3b1 was selected as the best treatment.
