Forage quality in Pisum sativum, treated by biological and synthetic active compounds
Ivelina Nikolova, Natalia Georgieva, Yordanka Naydenova
Abstract: The influence of single and combined biological active compounds of three insecticides NeemAzal, Pyrethrum (biological insecticides) and Nurelle D (synthetic pyretroid), two growth regulators – Polyversum (biological regulator) and Flordimex (synthetic regulator) and organic foliar fertilizer Biofa on the
chemical composition and enzyme in vitro digestibility of dry matter of spring forage pea (Pisum sativum L.) are established (2011 – 2013) at the IFC, Pleven, Bulgaria. The results demonstrate that single and combined application of studied biological and synthetic active compounds have a positive impact
on composition and digestibility of spring forage pea. A single treatment in budding stage increase CP, CF and hemicellulose content and decrease plant cell walls fber components content - NDF, ADF, ADL and hemicellulose. Significant increase of CP is established at Polyversum and Flordimex (by 10.1 and 11.9%), while increase of CF is slightly expressed. Optimal combination of expressed decrease in plant cell walls fber components content with significant increase of digestibility is established after applying of Biofa and combination Pyrethrum + Biofa. Digestibility reaches 71.0 and 70.4%, respectively with increase from 12.5 and 11.5%. Double application of biological active compounds in budding and flowering stages have significant influence on the composition and digestibility, but the influence is expressed in lower degree.
