| Abstract/Contents: | "Creeping Bentgrass Fairway Management: The fairway management study is being conducted to determine effects of irrigation frequency, clipping removal or return, nitrogen nutrition, and traffic on Penncross creeping bentgrass competition with annual bluegrass and maintenance of fairway quality. Turfgrass quality and color ratings increased with high nitrogen application in both traffic conditions. Responses to fairway playing conditions for load bearing capacity, divot tolerance and divot recovery, and ball speed in 1990 were similar for those reported in 1989. Leaf nitrogen content increased with frequent irrigation, clipping return, and high nitrogen treatment. A general trend was that soil nitrogen content decreased with frequent irrigation, clipping return, and high nitrogen rate under both traffic conditions. Low nitrogen application produced less thatch than high nitrogen application. Perennial-biotype verdure spread of annual bluegrass decreased with low nitrogen application in traffic and nontrafficked conditions. Attempts to infest this research area with annual-biotype annual bluegrass have failed. Perhaps indicating a strong competitive advantage toward the bentgrass fairway culture. Vertical Mowing Frequency and Mowing Height Effects on Putting Green Quality and Plant Stress: This project continues to study the effects of vertical mowing frequency and mowing height on putting speed, rooting, and stress resistance. Grooming by vertical mowing at 28 and 14 day intervals did not influence putting speed, under conditions of this study. Mowing height did influence putting speed. Mean ball roll for 1990 was 7% greater at 1/8 (3.2 mm) than at 5/32 (4.0 mm) and 15% greater at 1/8 than at 3/16 (4.8 mmm) inch growing heights. Vertical mowing intervals did not influence average monthly visual color and quality ratings. Mowing height did influence visual color and quality with the 5/32 inch having up to 49% greater quality than 1/8 inch mowing height in July 1990. Color ratings at 3/16 were up to 40% great than 1/8 inch mowing height in July 1990. Vertical mowing frequency did not incluence the vegetation index as measured by light reflectance. Syringing on a Creeping Bentgrass Green: A syringing study has been initiated to study interactive effects of nitrogen and potassium nutrition. The study was designed so treatment modifications over time would allow investigations of amount of water applied during syringing, and of application timing effects on syringing treatments. Very limited data were collected during 1990 due to weather and scheduling conflicts. However, the data collected do indicate a significant canopy turfgrass cooling influence from mid-day syringing. Now that another project leader had filled one of the vacant staff positions, greater emphasis will be directed toward this project. Currently, design and implementation aspects of this research project are under evaluation." |
