Abstract
The purpose of the work was determination of optimal density of plants and proper sowing rates of red fescue, on the basis of thousand seed weight (TSW), in cultivation for seed and for turf. In two experiments, conducted in the seasons of 2002–2004, the influence was studied of planting density on tillering and other characters determining seed yield and turf quality. The material consisted of four turf cultivars with different TSW. Three rates of sowing were applied: W1 — maximal, close to that used in practice, W2 — average (500 seeds per m2) and W3 — minimal, 250 seeds per m2. For seed yield, the best was the W2 density and for creeping forms even the W3. At the most loose sowing higher seed yield was obtained due to better tillering (up to 30 shoots per plant) and higher TSW. For turf establishment, sowing can be decreased up to 50 kg/ha (three- or fourfold), especially for chewing forms of red fescue. It should be considered, that turf compactness can be lower in the first season, but much better in the following years.
