A pot experiment was performed to investigate the influence of three groups of plant growth promoting rhizobacteria (PGPR), (1: Azospirillum brasilense and Bacillus cereus, 2: Pseudomonas fluorescens and Bacillus subtilis and 3: Azospirillum lipoferum and Enterobacter cloacae) on the yield and growth parameters of two wheat varieties, namely Misr 1and Sakha
The aim of this paper  to investigate the influence of Azospirillum brasilense, Bacillus cereus, Pseudomonas fluorescens, Bacillus subtilis, Azospirillum lipoferum, and Enterobacter cloacae) on the yield and growth  of two wheat varieties, namely Misr 1and Sakha 95, which were cultivated on saline clayey soil. The experiment contained four treatments for each variety (T1(control), T2(Azospirillum brasilense and Bacillus cereus), T3(Pseudomonas fluorescens and Bacillus subtilis ), and T4(Azospirillum lipoferum, and Enterobacter cloacae). The results show that Sakha 95 had higher growth and yield than Misr 1. Moreover, the used groups of PGPR significantly increased the yield and growth parameters of wheat plants. The highest plant length, spike length, spike number, the weight of 1000 grains, straw yield, and grain yield (77.95 cm, 9.67 cm, 16.14 spike, 43.5 g, 27.28 g/pot, and 19.18 g/pot, respectively) were recorded with T3 (Pseudomonas fluorescens and Bacillus subtilis) application. The interaction effects of wheat varieties and PGPR  on the above-mentioned parameters,  indicated that the highest plant length, spike length, spike number, weight of 1000 grains, straw yield, and grain yield were observed in Sakha 95 with application of T3 (Pseudomonas fluorescens and Bacillus subtilis) compared with Misr 1 and the control.  Salt-affected soils inoculated by Pseudomonas fluorescens and Bacillus subtilis   enhance the growth and reduce the cost of wheat production.
95, which were cultivated on saline clayey soil. The experiment contained four treatments for each variety (T1= control, T2= Azospirillum brasilense and Bacillus cereus, T3= Pseudomonas fluorescens and Bacillus subtilis and T4= Azospirillum lipoferum, and Enterobacter cloacae). The results showed that Sakha 95 had higher growth and yield than Misr 1. Moreover, the used groups of PGPR significantly increased the yield and the chosen growth parameters of wheat plants. The highest plant length, spike length, spike number, the weight of 1000 grains, straw yield, and grain yield (77.95 cm, 9.67 cm, 16.14, 43.5 g, 27.28 g/pot, and 19.18 g/pot, respectively) were recorded due to T3 (Pseudomonas fluorescens and Bacillus subtilis) application. For the interaction effects of wheat varieties and PGPR on the above-mentioned parameters, results indicated that the highest plant length, spike length, spike number, weight of 1000 grains, straw yield, and grain yield were observed in Sakha 95 after using T3 (Pseudomonas fluorescens and Bacillus subtilis). Thus, using PGPR, especially Pseudomonas fluorescens and Bacillus subtilis can be an effective and low-cost strategy to enhance wheat growth and production in salt-affected soils.
