Abstract Potato (Solanum tuberosum L.) production in semiarid regions is always constrained by water availability. This study was to evaluate the effects of straw strips mulch to potato growth, yield and economic benefits. The field experiment was conducted in northwest China in 2016 and 2017, including four treatments: (1), alternating narrow and wide ridges both mulched by black polyethylene film (PM); (2) alternating large ridges and small furrows with maize straw strips mulched only on the furrows (RS); (3) alternating the strips mulched with maize straw and bare plots with no ridges (PS); (4) traditional flat planting without mulching (CK). Results indicated that mulched treatments significantly (P
