| Abstract/Contents: | "The excessive use of nitrogen fertilizers on golf courses is scrutinized worldwide. For creeping bentgrass (Agrostis stolonifera L.) putting greens in the Midwest U.S., annual nitrogen rates range between 97-293 kg ha-1. Using alternative turfgrasses for greens may help decrease nitrogen use while maintaining turfgrass quality. Fine fescue turfgrasses are used for greens in Europe, and are known for lower nitrogen requirements and reduced input management. However, fine fescues greens have received limited attention in the U.S., and research on the amounts of nitrogen required for a reduced input fine fescue green is lacking. The objective of this study was to determine the lowest possible annual nitrogen fertilizer rate for maintaining a reduced input fine fescue putting green. Chewings fescue (Festuca rubra ssp. commutata), strong creeping red fescue (F. rubra ssp. rubra), slender creeping red fescue (F. rubra ssp. litoralis), hard fescue (F. rubra ssp. trachyphylla), colonial bentgrass (A. capillaris L.), and creeping bentgrass were established in St. Paul, MN. Plots were mowed at 5.1 mm, and were treated with either 0, 48.9, 97.7, or 195.3 kg ha-1 of nitrogen annually beginning May 25th, 2017. Turfgrass quality was assessed visually, using digital images, and using NDVI. During the first year of this study, Chewings and slender creeping red fescue maintained the highest quality of the fine fescues, and also maintained high quality at the low nitrogen rates when compared to both bentgrass species. During year two, the occurrence of summer patch disease (Magnaporthe sp.) resulted in a large decline in quality for all the fine fescues, but Chewings fescue plots were less effected overall. When managing a reduced input putting green, both Chewings and slender creeping red fescue may be suitable alternatives to creeping bentgrass when low nitrogen rates are used, but an active disease management program will be required." |
