Abstract/Contents:"Limited data exist concerning the mineral nutrient content of different cultivars for bermudagrass [Cynodon dactylon (L.) Pers.]. This field study was conducted to determine the effects of different rates of nitrogen (N) and potassium (K) on the macronutrient content, color, and quality of several bermudagrass cultivars. The cultivars utilized were: 'Ormond', 'Texturf 10', 'Tiflawn', 'Tufcote', and 'U-3' [Cynodon dactylon (L.) Pers.]; 'Midmo', 'Midway', 'Pee Dee', 'Santa Ana', 'Tifgreen', 'Tifway', and 'Tifway II' [Cynodon dactylon (L.) Pers. x Cynodon transvaalensis Burtt-Davey]; and 'Suntruf' [Cynodon magennisii Hurcombe]. The study was a 2 x 2 factorial with the factors being two levels each of N and K imposed on the cultivars. The N and K rates were 244 g N and 244 g K 100 m2 month-1 (low rates) and 488 g N and 488 g K 100 m2 month -1 (high rates) resulting in four N:K treatment combinations: 1) high N:high K (HH); 2) high N: low K (HL); 3) low N:high K (LH); and 4) low N:low K (LL). Plant tissue samples were collected in August of 1997 and 1998 and analyzed for N, K, phosphorus (P), calcium (Ca), magnesium (Mg), and sulfur (S). Turfgrass color and quality were determined monthly from May through October. There were differences both years in N, P, K, Ca, Mg, and S content among the cultivars under each of the four treatments. In 1997, N content was within the sufficiency range for all cultivars under each treatment except for Midway and Tufcote under low N:high K treatment. In 1998, six cultivars under the low N and both K treatments resulted in N levels less than 20.0 N kg-1. Potassium concentrations were above 20.0 g K kg-1 in only three instances in 1997 and less than that for all cultivars for 1998. Calcium concentrations were within the sufficiency range in only fice instances over the two years. For both years, Mg concentrations were below 2.0 g Mg kg-1 for all cultivars under all treatments, and concentrations for P and S were within the sufficiency range for those nutrients. There were differences for turfgrass color and quality among the cultivars under the four treatments. The high N:high K treatment resulted in higher color and quality ratings compared to the low N:low K treatment."
