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 on the protein and plant cell walls fiber component content and enzyme in vitro degradability of dry matter of spring forage pea - Pisum sativum L., variety Pleven 4, grown for biomass, the field crop experiment was carried out in the Institute of Forage Crops – Pleven - 2007-2009. At the single application of the preparations Atonic, Masterblend and Confidor, the forage with increased protein content was formed average with 7,5 g kg-1 in comparison with combined application. The protein changed as follows: 173,2, 154,3 и 152,6 g kg-1 influenced by the factor treatment stage from budding stage to budding-flowering and flowering. The content of NDF varied: 392,5 - 409,3 g kg-1. The highest value was reached at the single application of Atonic and for combined – Confidor-Atonic. Fiber fractions ADF and ADL decreased by 7,0 and 16,9% respectively under influence of the preparations with exception of treatment with Masterblend for ADF and Atonic for ADL. The once application at budding stage determined the highest values of ADF and ADL decreasing disproportionate towards once treatment at flowering stage and twice – at stages budding-flowering. Digestibility of dry matter of spring forage pea was high 70,8 - 73,65% as at single use was highest under treatment with Atonic and at combined – with Atonic-Masterblend. At budding stage the most strongly expressed was the influence of the triple combination Atonic-Masterblend-Confidor, at flowering stage and at budding-flowering stages – of the double combination Confidor-Masterblend in which was counted the highest productivity.
