Ocena odrastania muraw trawnikowych z udziałem śmiałka darniowego

Abstract

The aim of this work was to evaluate the usefulness of tufted hairgrass to establish turf lawns used extensively as a result of the impact of it’s on the degree of lawns regrowth. Field experiments were founded in April 2003. In one experiment were sown the seeds of five grass species in pure sowing on the plot with an area of 1 m2. It was tufted hairgrass, clump red fescue, rhizomes red fescue, tall fescue, kentucky – bluegrass. In the second experiment were sown mixtures of this grass species with tufted hairgrass. Seeds for these experiments came from IHAR in Radzików. In the first experiment, research factors were 5 species of grasses and 3 date of observation and in the second – 5 kind of mixtures and 3 date of observation. As a date for observation for the spring was adopted mid-May, for the summer mid-July, for the autumn mid-October. The study was conducted in the years 2004–2005 by making systematic observations once a season (spring, summer, autumn). Each year of the study the lawns regrowth were evaluated. This evaluation was made according to the COBORU methodology. Valuation used 9o scale, where 9 meant the best value of this feature. Regrowth of tufted hairgrass turf was slower than kentucky bluegrass or red fescue, and so this species which are commonly used in lawn mixtures with varying suitability. From the five lawn mixtures established on the tufted hairgrass base, a mixture consisting of 50% of the tufted hairgrass and red fescue the slowest regrowth was characterized. The slow regrowth rate of tufted hairgrass both in monoculture and in mixtures create the possibilities to use this grass species in greater extent to the establish of lawns especially those that will not require too frequent mowing.
