Abstract: The influence of preparations with different biological action Atonic, Masterblend and Confidor used alone and combined, once (budding and flowering stages) and twice (budding+flowering) was studied in the field crop experiment in IFC – Pleven during the period 2007-2010 on plant cell walls fiber components content and enzyme degradability in spring vetch. Plant cell walls fiber component fractions of vetch were influenced strongly posititive by the effect of preparations in all ways of treatment and stages of development, while the protein content of biomass was decreased. The NDF content was 402.0 – 416.4 g kg-1 dry matter biomass. The most strong effect had Masterblend 6,4% and Confidor-Atonic-Masterblend – 4.5%. The ADF content was influenced by Confidor 8.2 g kg- 1 (2,5%) and Confidor+Atonic 14.6 g kg-1 (4.5%). The ADL had comparatively high values 60.0– 66.0 g kg-1. Confidor most strongly influence increased ADL values 70.8 g kg-1 (10.0%) as well as Confidor+Atonic 69.4 g kg-1 (8.9%). The enzyme degradability of dry matter of forage was 63.0 – 71.1% and increased under the effect of all preparations, ways of treatment and stages of development.
