Abstract/Contents:Presents a study conducted to "determine the effects of eight N [nitrogen] programs which varied by annual N-rate and application timing on the above ground responses and measure seasonal soil N concentrations for three principal cool-season lawn grasses KBG [Kentucky bluegrass], turf-type tall fescue (Festuca arundinacea Schreb.; TTTF) and perennial ryegrass (Lolium perenne L.; PRG). Details methods and materials used in the study, stating that "cultivar blends of KBG, TTTF and PRG were established by seed. At seeding the entire study area received 73 kg [kilograms] P [phosphorus] ha-1 [per hectare]. The N-programs consisted of eight programs which varied in annual N, ranging from 0, 49, 73, 123, and 196 kg N ha-1 yr-1 [per year]...All treatments were arranged in a randomized complete block design with three replications." Reports that "the three species varied dramatically in response to N fertilizer inputs...Dry matter yield was significantly different between species ranking, TTTF>KBG>PRG. Kentucky bluegrass generally possessed the greenest canopy, when avereaged across all N treatments followed by TTTF and PRG." Concludes that "this study demonstrated that there are dramatic differences for species in response to N."
