Abstract/Contents:Presents a study with the objective of "[determining] the effects of four Green Releaf growth-enhancement programs on the growth, color, quality, and stress tolerance of both greens- and fairway-height creeping bentgrass." Experimental plots were evaluated for color, quality, density, and clippings weight. Results include that "Syber-Green might be slightly more effective than Green Releaf Optimal. The Green Releaf Dry treatment increased clipping weights on both the greens- and fairway-height turf, indicating turf growth. In addition, Green Releaf Dry increased color ratings on the green. Otherwise, there were no density or quality effects associated with this treatment, suggesting that the increased growth and color seen on Green Releaf Dry-treated plots was primarily due to the relatively high mineral (especially nitrogen) content of the material as well as to the high rate of application. Bichem 710-L was the worst performer of the four treatments. When compared with the control treatment, Bichem 710-L tended to have lower clipping weights on the fairway and lower color, quality, and density ratings on the greens. Interpreting these results was made more difficult by the fact that product effectiveness seemed to tail off at different rates before the next application was made, and ratings were sometimes taken in these periods of differential decreased effectiveness. Two protocol changes could help reduce these problems in further studies. First of all, decreasing the interval between treatments could prove beneficial. Secondly, consistently taking ratings at a certain number of days after treatment instead of weekly could help decrease the variation introduced by these 'tailing-off' effects."
