The effect of modified pratotechnology on herbage production of meadow sward was observed since 2001. Treatments were: mown once (1C) and twice a year with biomass removal — fertilized (2C + N) and unfertilized (2C), mulched twice (2M) and once a year (1M) and non- used plots (0). The yields of aboveground phytomass in 2001 and 2002 were highest on fertilized twice mown treatment {8.7 and 10.4 t DM/ha...
The experiment concerning the study of botanical composition of stands and yielding abilities was founded in 1966. The variants of fertilization for the evaluation: 0-P40 K100-N100 P40 K100- N200P40K100. The significant reduction of the species diversity was found in the nitrogen fertilization. Alopecurus pratensis L., was the most infested plant belonging to the rhizomatic species in both fertilization...
The usefulness of Festuca arundinacea Schr. (variety Kora) and festulolium F. arundinacea x Lolium multiflorum Lam. (variety Felina) as biofuel was observed in the year 2002. The energy accumulation and N content in the biomass during vegetation were studied in cca 14 days intervals. There were no significant differences in heating value neither by variety nor by samplings and they ranged from 16...
