Improvement of lawn grass response to shadow-stress

Abstract

On numerous occasion lawns are installed in different conditions, therefore its forming grass often suffer stress which reduce their quality and ornamental peculiarities. Nonetheless, negative environmental effects on grass could be reduced by the choice of suitable species for cultivation in existing climatic conditions and application of appropriate management techniques. Some agents (amine and humic acids, growth regulators, active and passive aeration, regulation of CO2 in soil) could be applied as light-stress compensation means. In order to investigate the influence of growth regulators, humic acids, amino acids, growth promoter on turf and grass quality parameters and to determine the most effective, the vegetative trial was performed in Elektrenai municipality Pipiri kes village during 2009. Results confirmed different response of assessed grass species on tested agents (Moddus 250 EC; Delphi and Humistar). Red fescue and perennial ryegrass were observed the most resistant for shadow conditions. Kentucky bluegrass and creeping bent-grass were the most injured of pathogens
