Treatments consisted of sufficient, low, moderate and severe deficit irrigation(irrigated with 100%(CK), 80%(T1), 60%(T2)and 40%(T3)of pan evaporation, respectively)in the flowe-ring to fruit-setting stage. The results indicated that water deficit significantly influences the growth rate of shedding shoots in the flowering to fruit-setting stage. With the increase of water stress, the inhibition of the shedding shoots aggravates. Deficit treatments significantly improve single fruit weight, soluble solid content, soluble sugar content and sugar/acid. Especially, the moderate deficit irrigation(T2)improves fruit yield 9.6% higher than that of the control and increases economic benefit by 33.92%. Therefore, appropriate deficit irrigation is of benefit to increasing gray jujube yield, quality and economic benefit.ª¤
