%0 Journal Article %T THE USEFULNESS FOR ENSILING OF CHOSEN PLANT FORMS OF SPECIES OF SILPHIUM GENUS %A JarosŁżaw PiŁżat %A WŁżodzimierz Majtkowski %A Gabriela Majtkowska %A Jan MikoŁżajczak %J Journal of Central European Agriculture %D 2007 %I Journal of Central European Agriculture %X Chemical composition and usefulness for ensiling of the chosen forms of species: S. perfoliatum was determined in different stages of vegetation. Forage fermantation coefficient of species form: I, II ,III during vegetation period from vegetative phase to seed setting phase was lower than 35. The fermentation coefficient IV form of species during the initial phase of seed setting amounted to 36,54, which ensured the correct fermentation. The high phenol acids content in I, II, III species form limits the possibility of using them for forage purposes. These species may constitute a potentially good raw material for the pharmaceutical industry. %K silphium %K forms of species %K stage of vegetation %K coefficient of ensiling ability %U http://jcea.agr.hr/articles/488_THE_USEFULNESS_FOR_ENSILING_OF_CHOSEN_PLANT_FORMS_OF_SPECIES_OF_SILPHIUM_GENUS_en.pdf
