| Abstract/Contents: | Describes experiments conducted on Tifgreen bermudagrass and Floratam St. Augustinegrass. States that Tifgreen bermudagrass and Floratam St. Augustinegrass were transplanted onto root observation boxes of the rhizotrons. Details the methods of the experiment, stating that Phosphorus (P) applications were made annually at 3# / 1000 sq ft., and Nitrogen and potassium applications were made at 1# of nutrient /1000 sq ft per growing month. The bermudagrass and St. Augustinegrass turfs were clipped weekly at 1 and 2 inches, respectively. Root growth rates of the grasses gradually decreased as fall soil temperatures declined. The growth rate in late October was 1/2 the rate of summer. Root growth continued for some 30 days after shoot dormancy. A severe and rapid root browning of the entire root systems was observed to occur on both turfgrasses within a few days following new leaf emergence. This onset of rapid root death and loss occurred 4 and 5 days after new spring leaf emergence. New root initiation took place 1 and 14 days after root browning for Tifgreen and Floratam turfs, respectively. In total, Tifgreen and Floratam were observed to have a 21 and 27 day delay, respectively, between old root browning, and an individual new root reaching a one foot depth. Spring root loss increases the susceptibility of these turfgrasses to the many types of stress. Sodding and vegetative establishment of either of these grasses is much more difficult during this root deficiency period than in late spring or summer. Raising cutting height, delaying first mowing, and lengthening the intervals between mowing are helpful in maximizing root growth. Other positive cultural practices may include applications of potassium and adequate availability of soil water. |
