| Abstract | ||||
| Salinity is one of the most brutal environmental factors limiting the productivity of crop plants. Thus, there is an urgent need for environmentally friendly techniques to enhance growth and productivity of wheat (Triticum aestivum L.) growing in saltinesoils. In our 2-year field experiments, we evaluated the effect of two beneficial plant growth-promoting rhizobacteria (PGPR; Azospirillum brasilense and Bacillus circulans) and the foliar application of potassium silicate (K2SiO3; PS) to improve growth and yield of three cultivars of wheat, namely Misr 1, Gemmeza 12 and Sakha 95, under salt-affected soils (EC=7.71). The results supported our hypothesis that the combined application of PGPR+PS significantly (P | ||||
