Abstract/Contents: | Treatments were applied to a 'Rebel' tall fescue turf established in May 1987 at the University of Nebraska John Seaton Anderson Turfgrass Research Facility, Mead, NE. Nitrogen treatments of 0, 1/3, 2/3, 1 and 1 1/2 lb actual N/ 1000 ft₂ were applied 5 May, 16 June, 7 July, 5 August, 11 September, 8 October. This gave seasonal N rates of 0, 2, 4, 6, and 8 lb/1000 sq. ft. Liquid urea (46-0-0) was used as the fertilizer. Brown patch developed rapidly during the growing season and stabilized at moderately severe levels by early August. At the 1 in cuttting ht, the level of N applied had every little effect on brown patch severity. However, at 2.5 in there was a noticeable increase in brown patch severity with increasing N level. Brown patch was light to moderate at 0 and 2 lb N and became moderatly severe at 4, 6 and 8 lb N. The most severe brown patch was at the 8 lb N level. The included chart provides the 1992 brown patch rating for 20 August and 3 September. |
