【Objective】 The effects of droughtresistant agents(DRA) and super absorbent polymers(SAP) on yield and the water use efficiency of cotton were studied in order to provide basis for application and promotion of water saving agents in Xinjiang.【Method】 The field experiments of different amount of DRA and SAP on cotton were carried out and changes of cotton yield,boll weight,and soil water use efficiency were analyzed.【Result】 The two drought resisting and water saving agents could significantly increase the cotton yield by 2.55%-29.71%,and improve the water use efficiency by 2.1%-29.8%;and using DRA enhanced cotton boll weight obviously but water saving agents couldn't;Overall,DRA is superior to SAP for helping the cotton growth;The application quantity and soil moisture have a certain influence on effects of DRA and SAP.【Conclusion】 DRA and SAP can be used in agricultural production of cotton.
