Abstract

One of the most important vegetable families commonly grown in around of the world is Cucurbitaceae for economic value, nutrition, consumer’s preference, general adaptability and extent of cultivation. Plant growth promoting rhizobacteria mostly associated with the plant rhizosphere have been established as beneficial for plant growth, yield and crop quality. They are important to promote the circulation of plant nutrients and reduce the need for chemical Fertilizers and interest in eco-friendly, sustainable and organic agricultural practices as well. Use of PGPR’s containing beneficial microorganisms in lieu of inorganic chemicals are positively known to affect plant growth and may help to sustain environmental health and soil productivity, even in biotic and abiotic stress conditions. PGPR’s also have potential bio-control agents against to a wide range of bacterial and fungal pathogens in agriculture. The effects of PGPR’s on physiological mechanisms, plant growth, yield and yield components, uptake of mineral elements and contents, biotic and abiotic stress conditions in Cucurbits vegetables and future perspectives have been discussed in the review.
