Резюме: In point of view to establish the influence of preparations with different biological effect – Atonic (growth stimulator), Masterblend (combined foliar fertilizer) and Confidor 70 VG (insecticide), applied single or combined, once (budding and flowering stages) and twice (budding + flowering) was estimated the potential energy feeding value and protein feeding value of spring forage pea (Pisum sativum L.) biomass, variety Pleven 4, grown for fresh mass in field crop experiment (2007-2009) carried out in the Institute of Forage Crops – Pleven. The highest energy feeding value was established for the forage obtained after treatment with the growth stimulator Atonic FUM 0.846; FUG 0.758 and highest protein feeding value TDP/PBD 130 g kg-1 and 109 and 100 g kg-1 PDIN, PDIE respectively. The combined application of biologically active preparations increased energy but not protein feeding value of spring forage pea. Energy feeding value estimated was the most significantly increased under pea treatment at budding stage at combined application of three preparations and at combined application of Confidor and Atonic. The protein feeding value estimated was increased at budding stage. Only the growth stimulator Atonic rose the protein feeding value at single application meanwhile at the stages budding and flowering.
