In 2000-2002 a field experiment carried out at the Pawłowice Agricultural Experiment Station, in the vicinity of Wrocław, investigated the effect of N fertilization and the date of harvest on the accumulation of nutrients in two pea morphotypes: Agra – leafless and traditional Rola cultivars. The dry weight accumulation in pea seeds, pod-shells and stems was determined by seed ripening, weather course and pea cultivar-specific factor, however it did not depend on the N fertilization. In the period from green to full maturity the plants demonstrated some changes: the share of seeds in seed yield increased, whereas the share of pod-shells and stems decreased; the content of total protein, fat, fiber and crude ash as well as P, K, Mg in seeds decreased and the share of NFE increased. In pod-shells and in stems the content of total protein, fat, NFE, P and the energy value decreased, while the content of fiber – increased. The share of seeds, pod-shells and stems in organic and mineral nutrients accumulation differed and dependent on the development phase and was cultivar-specific.
