| Abstract/Contents: | "Replicated trials were established in tall fescue swards (vc. `Crossfire' and cv. `Rebel Jr.' in 1994 and 1996, respectively) to test three mowing heights and three fertility treatments in a factorial design. Mowing treatments evaluated were: 0.75 in. mowed 3x/wk; 2.5 in. mowed 2x/wk; and 4 in. mowed 1x/wk. Fertility regimes evaluated were (per 1000 ft2): 0 lb N, 2 lb N (1 lb N about 1 Apr and 1 June) and 4 lb N (1 lb N about 1 Apr, 1 May, 1 Jun and 1 Jul). All plots received 1.5 N twice during the previous autumn. Brown patch severity was assessed visually for a 3-4 wk period of disease activity and crop recovery. Regression analysis showed increasing severity with increasing mowing height in both years. Increasing N rate was associated with increasing severity in 1994 but not in 1996. ANOVA interaction were non-significant in all assessments. Increasing mowing height and increasing spring/summer fertility may act independently to increase severity of brown patch in tall fescue in the Bluegrass region of Kentucky." |
