**4. Conclusions**

In ecological conditions, pea cultivation especially the Hubal variety (traditional form of foliage) allowed to obtain the largest seed yield and the smallest cultivation of yellow lupine independent on the morphological type. The self-completing varieties of faba beans, blue lupines, and yellow lupines were yielded at a higher level than varieties with a traditional type of growth. Significantly, higher yield of protein is provided by faba bean cultivation, while the smaller level of pea and yellow lupine.

Yellow and blue lupine seeds contained more fat than pea and faba bean seeds. Pea varieties, regardless of the form of foliage, accumulated a similar amount of this component, while more self-completing varieties of faba bean, blue lupine, and yellow lupine. Irrespective of the agroecological conditions, the seeds of the yellow lupine varieties were characterized by a higher protein and fiber content. Both varieties of blue lupine also characterized high fiber content. Unfavorable weather conditions during the growing season have positively influenced the accumulation of protein and fat in the seeds of all legume species. The seeds of the tested species contained a similar amount of potassium and phosphorus, a greater amount of ash characterized blue lupine of the Kurant variety.
