Production of above-ground phytomass of turf grass species during their extensive exploitation

Popis výsledku v původním jazyce

Dynamics of phytomass development of turf grass species Lolium perenne L. (L.p.), Festuca rubra sp. (F.r.) and Poa pratensis (P.p.) during an intensive 5-cut system was studied in the field experiment (2007-2009) and compared with mulching and interaction with N+PK fertilization. Dry matter production of P.p. (454.1 g.m-2 without fertilization and 586.7 g.m-2 with fertilization) was lower as compared with L.p. (from 502,3 g.m-2 to 680,6 g.m-2) and F.r. (from 450,8 g.m-2 624,6 g.m-2). N-fertilization at50 kg and 100 kg.ha-1.year-1 increased the phytomass production on average by 29.3 - 39.9%. Compared with unfertilized variants, the quickly-available N and the slowly-available N increased the phytomass production by 39.8% and 29.5%, respectively. The height of the plant stand was significantly higher due to N-fertilization only in L.p. Compared with mown stands, the height of mulched stands was significantly higher in L.p. and F.r. Mulching decreased the weight of roots and increased t
