- Abstract
The article discusses the use of plant growth-promoting rhizobacteria (PGPR) as a sustainable agricultural technique to improve maize and cowpea crops. PGPRs offer environmentally friendly solutions by promoting root development, increasing stress tolerance, reducing disease, and enhancing crop yields. The article emphasizes the need for further research on PGPRs and the importance of raising awareness among farmers and agricultural industry players about their benefits for sustainable agriculture. The interactions between microorganisms and host plants in the rhizosphere have a positive impact on plant growth. The composition of microbial communities in the rhizosphere is influenced by various factors, including the type of plant, growth stage, and environmental conditions. PGPRs promote plant growth through direct mechanisms, such as nitrogen fixation, phosphate and potassium solubilization, and siderophore production. They also employ indirect mechanisms such as antibiotic production, induced systemic resistance, lytic enzyme production, competition with pathogens, hydrogen cyanide production, and exopolysaccharide production. PGPRs can also help control abiotic stress and heavy metal toxicity in plants. The document specifically focuses on the application of PGPR in maize and cowpea cultivation, highlighting their positive effects on plant growth, nutrient uptake, and protection against pathogens. The use of PGPR-based biological formulations in maize and cowpea cultivation offers advantages such as promoting environmental sustainability, reducing production costs, and improving crop yields. The scalability and cost-effectiveness of PGPR-based strategies in agriculture depend
