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