On-farm trials were conducted over a six-year period to investigate the efficacy of alternative post-harvest residue management practices for production of seven species of perennial grass seed crops. Species evaluated included perennial ryegrass (Lolium perenne L.), tall fescue (Festuca arundinacea Schreb.), creeping red fescue (F. rubra L.), Chewings fescue (F. rubra subsp. commutata Gaud.), Kentucky bluegrass (Poa pratensis L.), orchardgrass (Dactylis glomerata L.), and dryland bentgrass (Agrostis castellana Bois. and Reut.). Residue management technique, species, and stand age influenced seed yield. Species with a bunch-type growth habit were more tolerant of residue management without straw removal than were species with a creeping-type growth habit. The agronomic feasibility of field burning alternatives was demonstrated for all species except creeping red fescue.
