Role of N2-Fixing Plant Growth-Promoting Rhizobacteria in Some Selected Vegetables

Abstract

Due to the increase in food-borne diseases, especially in recent years, consumers' orientation to healthy products and their emphasis on consumption force producers to environmentally friendly products. Nitrogen is the most widely used plant nutrient in the world. Nitrogen, a very expensive input due to its excessive use, pollutes the environment and causes nitrate accumulation in plants. Therefore, vegetable growers strive to replace chemical fertilizers such as nitrogen with environmentally friendly and cost-effective sources. PGPRs stand out in this regard and at the same time, their potential in environmentally and consumer-friendly vegetable production needs to be revealed. In this study, the importance and potential role of N2-fixing PGPR are discussed for the improvement of yield and yield components in environment-friendly vegetable production for healthy human nutrition.
