Abstract/Contents:"Alternatives to open-field burning of Kentucky bluegrass (KBG) are needed as burning is increasingly reduced through regulation. A KBG core collection of 22 accessions, developed from the USDA germplasm collection, along with nine check cultivars and 17 selected accessions, were tested in different residue management systems. Compared to open-field burning, yields were reduced by 76% when no residue was removed and 31% when residue was removed mechanically. On separate turf plots, turfgrass quality ratings were highest in the group of check cultivars, as expected. But some accessions in the core collection had both good turf quality and seed yield. Compared with open-field burning, some entries showed no reduction in yield with mechanical residue removal, whereas others were strongly reduced. The results suggest that genotype selection is an important factor in maximizing seed yields under no-burn residue management systems."
