The aim of the two years study was to analyze silages made from leafed (L) or semi-leafless (SL) peas or bi-crop of SL pea with spring barley (SLxB). The experimental purpose was that agricultural practice needs more information on the chemical composition and quality of legume silages. The crops were ensiled in special laboratory silos equipped with a fermentation cap enabling gas leakage. No silage additives were used. The SL pea silage had significantly higher DM and starch; but lower CP and NDF in contrast to the L silage. The study confirmed the hypothesis that the quality of SL silage is better than L silage, but worse than SLxB.
