Abstract/Contents: | Presents a study "to compare the efects of Perk ['a new ammoniacal nitrogen based fertilizer that also contains iron and manganese'] and ammonium sulfate on the color and yield of Kentucky bluegrass." Results include "there were significant differences in color between treatments 7 and 14 days after application. Sevel days after teratment, Perk at 0.4 lbs N/1,000 sq ft provided the best color; and Perk at 0.2 lbs N/1,000 sq ft was equivalent to ammonium sulfate at 0.4 lbs N/1,000 sq ft and significantly better than ammonium sulfate at 0.2 and the untreated control. Fourteen days after treatment, only Perk at 0.2 lbs and ammonium sulfate at 0.4 lbs were significantly better than the untreated control. There were no significant differences in color between treatments 21 days after application. There were no significant differences in yield between treatments on any of the four rating dates. The lack of differences for yield may be the result of low application rates of nitrogen." |
