Perennial Ryegrass Mowing Quality and Appearance Response to Three Nitrogen Regimes
- V. A. Gibeault and
- D. Hanson
Six perennial ryegrass (Lolium perenne L.) cultivars established in San Jose, Calif., USA, were subjected to three N fertilization regimes and observed for turfgrass quality and mowing characteristics. Cultivars tested were ‘Manhattan’, ‘S-321’, ‘Pennfine’, ‘NK-100’, ‘Lamora’, and ‘Linn’. Nitrogen treatments consisted of 73, 146, and 292 kg/ha/year. Average turfgrass quality and mowing quality ratings increased significantly with increased N. Manhattan had the best mowing characteristics followed in ranked order by S-321, Pennfine, NK-100, Lamora, and Linn. Cultivar turfgrass quality ratings largely followed the order expressed for mowing quality. The data indicate that mowing quality is an inherent characteristic of perennial ryegrass cultivars and is difficult to modify except by high N applications. For turfgrass quality ratings, 35 % of the variability was due to fertilization and 65 % to cultivar. For mowing quality, 4 % was due to fertilization and 96 % to cultivar.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
