| Abstract/Contents: | "The perennial ryegrass (Lolium perenne L.) cultivars Manhattan and Manhattan II and a blend consisting of equal proportions by seed weights of each were used to study the influence of cultivar treatment, nitrogen (N) rate, and N-source on brown patch (Rhizoctonia solani Kühn) severity and turf quality. The N-sources were urea and SCU and were applied between May and October 1993 - 1996 at rates of 0, 10, 20, or 40 g N m-2. Among the cultivar treatments and the N-rates, significant differences in brown patch severity and turf quality were observed. In general, brown patch was less severe and turf quality was higher at N-rates of 40 g N m-2 per season when compared to 0, 10, or 20 g N m-2 per season. Turf treated with 40 g N m-2 showed blight levels that ranged from a low of 2.8 to a high of 4.5 on a 1-10 scale compared to the high and low ratings for 10 g N m-2 which were 3.0 and 6.4, respectively. The blending of the brown patch-resistant Manhattan II with the more susceptible Manhattan resulted in less brown patch injury and higher quality turf than Manhattan alone. Significant interactions between N-source (SCU and urea) and N-rate and between N-rate and cultivars were detected for both brown patch severity and turf quality on some evaluation dates. When compared across N-rates, the differences in brown patch severity or turf quality between N-sources were not consistent. Turf quality was negatively correlated with brown patch severity." |
