In order to study the effects of supplementary irrigation and biofertilizers on grain yield, dry matter remobilization and some physiological traits of barley (Hordeum vulgare L.) under rainfed condition, a factorial experiment was conducted based on randomized complete block design with three replications at in 2017. Factors included irrigation at three levels (no irrigation as rainfed (I1), supplementary irrigation at 50% heading (I2) and booting stages(I3) and biofertilizers application at four levels (without biofertilizers as control (Q1) , application of mycorrhiza(Q2), Azetobacter(Q3), both application of mycorrhiza and Azetobacter(Q4). The results showed that supplementary irrigation at heading stage with both application of mycorrhiza and Azetobacter increased efficiency of PSII photochemistry (Fv/Fm(, chlorophyll index and relative water content of flag leaf compared to non-application of biofertilizers under rainfed condition. Rainfed condition and no application of biofertilizers increased electrical conductivity and contribution of dry matter remobolization in grain yield. The highest and the lowest grain yields (268.2 and 206.5 g m-2 respectively) were obtained at supplementary irrigation at heading stage with both application of mycorrhiza and Azetobacter, and no application of biofertilizers under rainfed condition. In conclusion, it seems that application of biofertilizers and supplementary irrigation can increase grain yield of barley under rainfed condition due to improving some physiological traits.
