Effect of VAM and Azospirillum brasilense on photosynthesis, nitrogen metabolism and grain yield in wheat

Studies on inoculation with Azospirillum brasileme and VAM (Vesicular Arbuscutar Mycorrhiza) fungi revealed their beneficial effect on plant growth and yield under pot culture conditions. Azospirillum inoculation enhanced root growth whereas VAM enhanced shoot growth resulting in altering the root: shoot ratio. Dual inoculation of enhanced chlorophyll content, Photosynthetic rate (Ps), Nitrate reductase activity (NRA) and Glutamine synthetase activity (G.S.). Dual inoculation of VAM and Azospirillum caused synergistic effect in the growth.
