Growth effects of Pseudomonas, a Plant Growth- Promoting Rhizobacteria on Spinach (Spinacia oleracea L.) - A Review

Abstract

Plant growth- promoting rhizobacteria (PGPR), is a consortium of such bacteria which colonizes the roots of plants and show beneficial effects on growth and yield of plant. Pseudomonas is found to be most potent PGPR, occurring globally and having positive effect on productivity of plant. This review unravels several species of Pseudomonas which enhance growth and yield of spinach and can be used as biofertilizer. Certain species of Pseudomonas have been discovered which in absence of any chemical fertilizer can increase productivity of spinach alone. Investigation of such PGPR in case of spinach is quiet important as spinach cultivation make use of large amount of chemical fertilizers which are deleterious to health of crop, environment and human beings altogether. This review also introduces certain methods of inoculation of Pseudomonas sp. which encourages colonization around root or seeds of spinach, hence upgrading its association with spinach and yield in short. Thus, this review draws attention to explore more about Pseudomonas in case of green leafy spinach, inorder to gain large scale productivity and field application of it, which promotes organic farming and goodness of well-being.
