Effect of reclaimed water irrigation on yield and quality of fruity vegetables

For promoting feasible classification of crops for reclaimed water irrigation, the effect of reclaimed water irrigation (RWI) on the yield and quality of fruity vegetables was conducted. The yield of fruity vegetables significantly increased under the condition of RWI. The tests results indicated that the average yield of tomato and cucumber under the condition of RWI increased by 15.1% and 23.6%, and the average yield of eggplant and kidney bean under the condition of RWI increased by 60.7% and 7.4% compared with control check. There were no significant differences of reclaimed water irrigation on water content, crude protein, amino acid content, soluble sugar, vitamin C, coarse ash, nitrate, nitrite and nutrition indexes of fruity vegetables. Both nitrate content and nitrite content under the condition of RWI were below the standard limit. The study can provide technical basis for selecting the crops which are suitable for reclaimed water irrigation.
