ASA-CSSA-SSSA 2005 International Annual Meeting November 6-10, 2005, in Salt Lake City, Utah. Technical Abstract: Allowed managements on Conservation Reserve Plantings (CRP) include mowing and burning to reduce weed growth, and rotational haying. We conducted a study to determine if there were detrimental effects of timed burns and hayings applied to a cool-season grass (Bromus inermis L. and Festuca arundinacea Shreb.) with birdsfoot trefoil (Lotus corniculatus L.) CRP. Swards were sampled before a management treatment was applied, then post-treatment the sward was monitored repeatedly (June, October, and June) for changes in species proportion and the contribution of species to sward productivity and quality. Other forb and weed species were monitored. Few effects of managements were noted. Yield differences were observed only at the second June sampling; all managements were significantly higher than the control, but not from each other. Changes in botanical composition of the sward may result from the type and timing of management, but management treatments generally did not impact ADF, NDF, or CP significantly. The results indicate that a single management event on CRP does not have a detrimental effect on yield or herbage quality.
