Abstract
Disclosed are methods of enhancing plant growth, comprising a) treating plant seed with an effective amount of at least one phosphate solubilizing microorganism that may include a strain of the fungus Penicillium, and b) treating the seed or plant that germinates from the seed with an effective amount of at least one lipo chitooligosaccharide (LCO) and/or at least one chitoogliosaccharide (CO), wherein upon harvesting the plant exhibits at least one of increased plant yield measured in terms of bushels/acre, increased root number, increased root length, increased root mass, increased root volume and increased leaf area, compared to untreated plants or plants harvested from untreated seed.
