| Abstract/Contents: | "Potassium fertilization rates used for 'Tifway' bermudagrass [Cynodon dactylon (L.) Pers. X C.transvaalensis Burtt-Davy] vary greatly among turfgrass managers and there is no consensus as to the actual quantity required or as to the best Potassium (K) source to use. Effects of K source and rate on Tifway bermudagrass shoot and root growth, quality and tissue K concentration were studied in a 3-yr field study in Central Florida. Turf was grown on an Arredondo fine sand (loamy, siliceous, hyperthermic, Grossarenic Paleudult). Two K sources (KCI and K2SO4) were applied at 8 rates (0, 3.7, 7.4, 9.8, 14.7, 22, 29.4, and 36.8 g K m-2 90 d-1) in conjunction with N applied monthly at 4.9 g m-2. Potassium chloride produced a more rapid shoot growth than did K2SO4, but this effect may be linked to the N source. Bermudagrass shoot growth rate and tissue K concentrations were increased by K fertilization up to 7.4 g K m-2 90 d-1. There was no additional increases in either of the aforementioned parameters, regardless of the K level applied. Turfgrass quality and root weight were not influenced by K application. Greater root weight was observed during May, June, and July than August, September, and October. Observed turfgrass growth responses to Mehlich-1 extractable K levels suggest that 30 mg K kg-1 soil may be adequate for optimum growth. For an N application rate of 4.9 g m-2 mo-1, K fertilization levels above 9.8 g K m-2 90 d-1 probably will not enhance Tifway bermudagrass shoot and root growth, quality, or tissue K concentration." |
