| Abstract/Contents: | "In turfgrass management studies a significant cultivar x fertilizer (CxF) interaction indicates, among several interpretations, that cultivar A grows best using fertilizer product B. This study was conducted in Idaho from 2000 to 2008 using six Kentucky bluegrass (Poa pratensis L.) and four perennial ryegrass (Lolium perenne L.) cultivars fertilized with six granular products (and an untreated control) applied in Sep. or Apr.+Sep. Total applied N and K over the trial duration each correlated positively with soil organic matter (OM) content. Bluegrass cultivar affected turf quality on 95% of rating dates versus 100% of the time with ryegrass. Fertilizer treatment influenced turf quality 100% of the time with bluegrass and 74% of the time with ryegrass. A significant CxF interaction was rare by comparison, occurring 10% of the time with bluegrass and 5% of the time with ryegrass, and in both species primarily during spring greenup. 'Huntsville' bluegrass and 'Buccaneer' ryegrass, the lowest performing cultivars in the trial, also showed the least responsiveness to fertilizer on quality. A twice-yearly application of Poly Supreme fertilizer in bluegrass resulted in fewer dandelions (Taraxicum officinale W.) than all once-per-year treatments. Huntsville had more dandelions m-2 than 'Rambo,' and Buccaneer had more than the other three ryegrasses. At the end of the trial, fertilizer effects on quality remained significant in bluegrass for 1.6 yr after the last fertilizer application. By 2.6 yr the fertilizer effect had dissipated for both species." |
