Use of lipo-chitooligosaccharides and/or chitooligosaccharides in combination with phosphate-solubilizing microorganisms to enhance plant growth

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 amou...

Zusammenfassung:	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.
