| Abstract/Contents: | "Nitrogen fertilizers containing water-insoluble N forms afford turfgrass managers greater flexibility in formulating their nutrient management plans. Improved understanding of enhanced efficiency fertilizer N recovery by the Kentucky bluegrass system will support development of responsible application rate thresholds by regional agencies. The experimental objective was to systematically evaluate, under an array of field conditions, Kentucky bluegrass vigor/yield response following single applications of conventional or polymer-coated granular urea-N fertilizers. In May of Year 1 & 2, granular urea-based N fertilizers were applied to randomly-selected plots at a N rate of 43.9 or 87.8 kg ha-1 (0.9 or 1.8 lbs N / 1000 ft2). An unfertilized control plot (0 kg ha-1) was maintained in each block. A fabricated chute and 'micro-bagger' was installed on the 56-cm rotary mower to collect weekly clipping yields from the centers of each plot. Clippings were dried to constant mass in a forced-air oven (65 C) and transferred to desiccators for storage. The mass of dry clipping samples was determined at 1-mg resolution and recorded. Turfgrass vigor/yield was modeled by main effects and interaction of fertilizer treatment and DAT using the mixed procedure. Component means of this significant interaction were parsed by traditional pairwise analysis using Fishers Protected least significant difference. Results are presented." |
