Wpływ chemicznego i mechanicznego zwalczania Taraxacum officinale na zawartość NDF i ADF w runi łąkowej
The aim of this study was determine the effect of different methods of Taraxacun officinale control on the fraction of fibers, namely NDF and ADF in the meadow sward. Experiment was founded in 2007 on permanent grasslands in the śelków village near Siedlce (geographical coordinates: 52º08'N and 22º11'E) and was conducted until 2009. The field experiment was set up in randomized blocks in 3 replications. Experimental factors were two mechanical methods of Taraxacum officinale control by the pulling and mowing, and four selected herbicides (Rancho EC 242, Bofix EC 260, Starane 250 EC and Mniszek 540 SL). Plot area was 9 m2 . In each growing season three cuts were harvested. In the studies the content of fiber fractions NDF and ADF in meadow sward were determined. Used chemical methods of Taraxacum officinale control may affect on the feed uptaking, especially on the objects where herbicide Mniszek was used. It’s is evidenced by the highest content of neutral-detergent fiber fractions in the feed in compare to other objects. The feed from the objects with the mechanical method of Taraxacum officinale control the lowest digestibility was characterized. From chemical methods of dandelion control, the greatest influence on fooder digestibility had Starane herbicide (fluroksypyr in the form of ester 1-methylo heptylov).
