During 2005-2007 the effect of two cereal varieties: i common wheat and - ii Triticale, as predecessors and the choice of production methodology on the chemical composition, nutritional value, energy yield and feed units of the grain of winter pea variety Mir was investigated. The study was conducted at Trakia university, Stara Zagora in conditions of organic and conventional production. It was found that neither the predecessor nor the agricultural method have significant effect on the chemical composition and content of GE, ME, FUM and FUG in the grain of winter pea. Yields of GE, ME, FUM and FUG were higher in conventional agriculture and after wheat as predecessor. The most influential factor on these parameters is the agricultural method, seconded by the influence of climatic conditions. The predecessor has the lowest effect on the parameters observed. The energy yield and feed units correlates well with the total amount of rainfall during the growing season and rainfall during the month of February.
