    Abstract

    © 2014 Elsevier Ltd. Irrigation of farmland is a popular agricultural practice in semi-arid areas in China. However, little is known about the impacts of different irrigation strategies on grain yield and soil microbial communities, particularly economically-important arbuscular mycorrhizal (AM) fungi. The aim of this study was to optimize irrigation strategies to integrate maximized grain yield, AM fungal diversity and water productivity (defined here as grain yield per unit water supplied). Six irrigation strategies consisting of different amounts of water supplied and time of supply were imposed for field-grown winter wheat ( Triticum aestivum) in a typical cropping system in northern China. Results showed that all irrigation strategies significantly increased grain yield compared with the non-irrigation practice ( P
