In years 1999-2000 an experiment was carried out in the Brody Experimental Station in which the author assessed the usefulness of 20 cultivars of Festuca rubra and 4 cultivars of Festuca ovina for extensive lawn utilisation in the year of sowing and in the first year of utilisation. The experiments comprised the following determinations: the degree of plant tillering (9° scale), number of leaves per...
Advances in the preparation of grass mixtures, which occurred in the course of years, resulted in the reduction of the use of single grass species. Utilising increasingly comprehensive information about possibilities of grass competitiveness as well as their response to site conditions, it is easy to select appropriate components for seed mixtures. When deciding to sow a single species, it is essential...
The determination of the turf grasses seeded in Grass-Paver grate growth and development was the aim of the study. The grate construction is based on the rule of honeycomb. The three grass mixtures (1 Dutch and 2 Polish) and three substratums different in percentage of sand (90, 60, and 40) were analysed in this study. The study has proved that construction margins have not deleriorated the conditions...
One of the reasons for emergency failures and poor sod formation on the grass sports fields can be found in poor seed ąuality of some species included in the mixtures. Moreover, contribution of individual components in the mixture often differs from the composition declared on the package. The studies carried out showed that out of 7 grass mixtures for the sports fields sodding, the share of seeds...
The choosen species and varieties of gazon grasses sown in a pure sowing and mixtures on sport lawns were investigated. In the year of sowing estimated: emergence of plants, propagation and general aspect (scale 9°). Exact experiment microfields founded on 14 may 1998 with split-plot method, there times repeted, on antropogenic soil, formed from loamy sand. Soil before sowing soil was enriched in...
Breeding work started already in the thirties, but the first six species of lawn grasses were entered into the Register of Cultivars as late as 1966. Dynamic development of the breeding work and species evaluation based on the instructions worked out, started in the eighties (Plant Breeding and Acclimatization Institute, Research Centre for Cultivar Testing). In recent years, there is a growing regress...
