Paddy plants inoculated with PGPR show better growth physiology and nutrient content under saline condition

The possible role of plant growth-promoting rhizobacteria (PGPR) to alleviate salt stress during plant growth has been studied on paddy rice (Oryza sativa L.) ’GJ-17’ under greenhouse conditions; the study included growth parameters, mineral concentration, and antioxidant enzyme...
