Comparison of Granular and Liquid Nitrogen Fertility on 'TifEagle' BermudagrassF.W. Totten, H. Liu, L.B. McCarty, J. Toler, and C. BaldwinObjective Determine differences in efficacy between liquid and soil applied N fertilizer, Observe responses (e.g., turf color, density, rooting, and tissue N content) to N fertilizer treatments.Materials and MethodsVarious rates and ratios of granular and liquid fertilization were used to compare turf quality, turfgrass clipping yield, and root biomass on a newly established TifEagle' bermudagrass green constructed to USGA specifications from April to November 2003 and 2004. Treatments consisted of two annual nitrogen inputs, 190 and 254 kg/ha (3.9 and 5.2 lb N/1,000 ft-2) using 100% granular fertilizer, 50% granular + 50% liquid fertilizer, and 100% liquid fertilizer. Field plot size was 1.8m x 1.2m (6 ft x 4 ft). The study design was a randomized complete block with three replications. Foliar and granular applications were conducted biweekly from May to September. An 18-3-18 granular fertilizer was used, and liquid fertilizer applications were made using Daniels 10-3-5 and 5-0-7 products (Progressive Turf Inc, Atlanta, GA). Visual turf quality (color and density) was evaluated every 14 days from May to September using a scale 1 to 9, with 9 = excellent, 1= poor. A rating
