Abstract/Contents:"Effects of nitrogen or potassium applications on the turf colour, density, uniformity, turf clippings of turf type perennial ryegrass (Loium [Lolium] perenne) were studied. The results showed that nitrogen fertilizer improved the turf colour and enhanced the turf quality significantly. The fertilizer effects at the rate of N 3 g/m2 to N 12 g/m2 lasted 13 to 48 days, which indicated the intervals of fertilization. The relationship between clipping yields and N fertilization could be expressed as Y=-0.4426X2+16.392X+39.93, (R2=0.9996), where Y= clipping yields, and X=N application rate. Potassium did not show significant effects on the ryegrass growth and turf quality under the experimental conditions."
