| Abstract | ||||
| Potato (Solanum tuberosum) is globally considered the fourth most important crop for human food consumption. Therefore, increasing potato production is demanded, however, the high salinity in different areas limits reaching this aim. Hence, plant growth-promoting bacteria (PGPBs) may be the suitable solution for this situation as it might improve the growth and production of potatoes under salt stress. In this study eight bacterial isolates (Bacillus tropicus (WHS48), Metabacillus iocasae (WHS98), Bacillus velezensis (WHS114), Bacillus haynesii (WHW37), Bacillus thuringiensis (WHS259), Bacillus paramycoides (WHS267), Halomonas salifodinae (WHS325), and Bacillus licheniformis (WHS343) were isolated, from the soil and water of Wadi El-Natrun, Egypt; characterized and identified as PGPBs. The impact of these isolates on potato tuber production was studied. Generally, the tested bacterial isolates have improved tuber production, catalase and peroxidase activity. | ||||
