Abstract

A 3-year field study was conducted to determine the influence of nitrogen (N) application timing on the growth and quality of a turfgrass mixture consisting of perennial ryegrass (Lolium perenne L.), Kentucky bluegrass (Poa pratensis L.), creeping red fescue (Festuca rubra var, rubra L.), and chewings fescue (Festuca rubra var. commutata Gaud.) under irrigated conditions. Nitrogen was applied annually at the rate of 30 g m(-2) year(-1), with six application regimes: control (no N), single spring (30 g m(-2)), single fall (30 g m(-2)), spring + fall (15 + 15 g m(-2)), spring + summer + fall (10 + 10 + 10 g m(-2)), and monthly from April through September (5 g m(-2)).
