Objective and Findings: Water limitation is one of the important and adverse environmental constraints restricting growth and development of plant particularly in arid and semiarid regions. Drought stress induces generation of reactive oxygen species which affect almost every aspect of physiology and biochemistry of a plant, resulting in a reduction in its yield. Application of some stress modulators (vermicompost, mycorrhiza and foliar spraying of putresin and nano zinc oxide) increases growth, yield and the resistance of plants against various environmental stresses such as water limitation. However, the aims of this study was to investigate the effects of some stress modulators on compatible osmolytes and some physiological traits of barley under water limitation conditions. Based on these results, it seems that application of stress modulators (vermicompost, mycorrhizal, zinc and putrescine) can increase grain yield of barley due to improvement of chlorophyll content, antioxidant enzymes activity, compatible osmolytes and some physiological traits.
