Abstract Impact of furrow irrigation above mulch and under mulch on‘Dongsheng No.1’tomato’s growth，yield and water use efficiency were studied with conventional furrow irrigation as the control．The results showed that soil water content was maintained with certain scopes，more readily with furrow irrigation above mulch．Tomato growth was more preferable with furrow irrigation under mulch，and less prone to senescence．Yield of furrow irrigation under mulch was increased significantly by 11.34% than the conventional furrow irrigation．By the contrast，with conventional furrow irrigation，water consumption of furrow irrigation above mulch and under mulch were 31.33% and 27.00% less，respectively and water use efficiency were increased by over 50%．
