EFFECT OF PLANT GROWTH PROMOTING RHIZOBACTERIA AND P2O5 ON SOYBEAN (GLYCINE MAX L.) CROP
Plant growth promoting rhizobacteria (PGPR) colonize plant root and they remain with the plant root in rhizospheric region. They are beneficial and enhance the plant growth by direct or indirect means. In the present study pot experiment was conducted during kharif season during year 2010-11 at the Department of Environmental Science, Babasaheb Bhimrao Ambedkar (A Central University Lucknow U.P. to study the performance of the Plant Growth Promoting Rhizobacteria (PGPR) and P2O5 alone and in combination with each other on soybean (Glycine max L.) crop. The result of the experiment revealed that PGPR- L1+ P2O5 significantly affected the seed germination, root - shoot length, root and shoot-fresh and dry weight, vigor index and biomass production. It also affects the phygiological properties of the plant such as chlorophyll a, b, total chlorophyll and carotenoid content. The in-vivo bioassay germination test by using PGPR showed that the seed germination was between 80 to 90 percent
