LCO Applications provide improved responses with legumes and non-legumes
LCOs (Lipo-chito-oligosaccharides, a.k.a. Nod factors) are signal molecules produced by rhizobia that are essential for the nodulation process in legumes. Formulations for soybeans, peanuts, alfalfa, and peas/lentils combining the respective LCO and rhizobia for each legume have been developed and commercialized. LCO seed application of non-legumes such as corn, cotton, and wheat also demonstrate increased growth parameters, including root and shoot dry biomass in greenhouse studies, and enhanced yields in field trials. Root examination with the WinRHIZO scanner proved data demonstrating an increase in root length, surface area and volume. In addition, foliar applications of LCOs on legume (soybean) and non-legume (corn) in greenhouse and field trials improved plant growth parameters, including yield. LCO treated soybean and wheat seeds were rinsed with sterile water and this rinsed-off water was used to investigate LCO on-seed longevity by root hair deformation of Siratro (Macroptilium atropurpureum). LCO applications with legumes and non-legumes applied as seed treatments, in-furrow, and foliar spray have provided improved plant growth and yield responses.
