Irrigation management effects on nitrate leaching and mowing requirements of tall fescue
… experiment, sub-plots consisted of unfertilized turf, and N applied as urea or polymer-coated urea at 122 and 244 kg ha⁻¹ yr⁻¹. Suction lysimeters at a 0.76 m depth were used to extract nitrate leachate bi-monthly. Turf quality was rated weekly. In the second experiment, subplots were mown at 5.1 …

Drought and salinity tolerance of cool-season turfgrasses
… increased use of recycled water/saline water for turfgrass irrigation in arid and semi-arid climates, there is an increasing demand for drought and salt tolerant turfgrass. Kentucky bluegrass (Poa pratensis L.), tall fescue (Festuca arundinacea Schreb.), and perennial ryegrass (Lolium perenne L.) …

Evaluation of plant growth regulators for managing fescue turf along highway rights-of-way
… plus mefluidide afforded a significantly higher turf quality than metsulfuron plus mefluidide. ACP 2100 at 120 and 180 g ha⁻¹, imazethapyr plus imazapyr, DPX L5300 plus mefluidide at 70 plus 140 g ha⁻¹, and metsulfuron plus mefluidide gave the most consistent seedhead suppression. When treating …

Evaluation of fine fescues as alternative golf course fairway turfgrasses
… currently being used for golf course fairway turf. Low-input fine fescue species could be able to withstand the pressure from typical turfgrass disease and stresses while producing acceptable turf and excellent playing quality with fewer overall inputs of pesticides, water, and fertilizer. …

Influence of iron and cytokinin on Cynodon spp. cultured at chilling temperatures
… to temperatures low enough to limit growth and turf quality. Research was conducted to investigate the influence of foliar iron and cytokinin applications on bermudagrass growth during fall and spring. The relationship of photosynthesis, respiration, and nonstructural carbohydrate composition to …

Influence of Isolate, Cultivar, and Heat Stress on Virulence of Rhizoctonia zeae on Tall Fescue
… is a common pathogen of tall fescue and other turfgrasses in various regions of the United States. Disease caused by R. zeae typically occurs during hot, humid summer months when conditions are ideal for growth of the fungus but less than ideal for growth of tall fescue. While R. zeae has been …

Topdressing and aerification programs on creeping bentgrass fairways
… change. Topdressing and aerification increased turf quality at North Dakota but not Iowa. Soil in plots aerified in the fall had 4% lower soil strength than those aerified in the spring at both sites. Soil in aerified plots had a 48% increase in water infiltration as compared to the control at …

Evaluation of novel techniques to establish and transition overseeded grasses on bermudagrass sports turf
Most professional turf in Virginia is comprised of bermudagrass (Cynodon dactylon L.) or (Cynodon dactylon x C. transvaalensis Burtt Davy) as a monoculture in summer and overseeded with perennial ryegrass (Lolium perenne L.) (PR) in winter, during bermudagrass dormancy. Two transitions are required …
