| Abstract/Contents: | "Five cultivars of creeping bentgrass (Agrostis palustris Huds. 'Emerald', 'Penncross', 'Penneagle', 'Prominent', and 'Seaside') and annual bluegrass (Poa annua L.), a weed, were grown in pot culture in silica sand and supplied with nutrient solutions in which 0%, 25%, 50%, 75%, or 100% of the N (210 mg-liter-1) was NH+4 and the remainder was NO-3. Growth rate, as measured by new leaves and tillers, and final size, as measured by leaf width, leaf number, tiller number, and cover, were significantly different among species and cultivars and among N ratios. All species/cultivars produced their best growth with some mixture of NH+4-N. Annual bluegrass grew better in high-NH+4 conditions, while the bentgrass cultivars grew as well or better in high NO-3 conditions. There were significant differences among the bentgrass cultivars in their sensitivity to N source, with 'Penncross' being the most sensitive and 'Seaside' the least." |

Corrigendum: Vol.25, No.8, p.841 notes that references in the text to ammonium and nitrate nitrogen, where printed as "NO-3" and "NH+4", have been reversed. To correct this, "NO-3" should be read as "ammonium" and "NH+4" as "nitrate". References that are written as "ammonium" or "nitrate", and references in the figures and tables, are correct as printed.
