Developing Prairie Cordgrass as a Cellulosic Bioenergy Crop
Prairie cordgrass (PCG) (Spartina pectinata) is a native warm-season grass that grows well on poorly drained and/or salt-affected soils and has potential of biomass yield up to 20 metric tons per hectare in northern environments. This project determined the best genetic resources for developing improved populations and best planting system and agronomic management practices for sustainable PCG biomass production in land not suitable for traditional row crops or other perennial prairie grasses.
Lee’s group identified the best 20 lines for high biomass yield production. Field research indicated that prairie cordgrass has a potential of sustainable biomass feedstock production on marginal lands associated with abiotic stresses such as salts and water logging.
Lee’s group completed its nationwide prairie cordgrass germplasm collection, established a germplasm collection nursery with 109 wild populations, and began evaluating germplasm. Researchers collected biomass yield and phenotypic data for the germplasm collected for 2009. Biomass yields were evaluated in agronomic management practices trials including the planting system and N and harvest management trials established in 2009.
