The influence of red light radiation and nitragine treatment of five chickling vetch seed cultivars, on basic nutritional component and mineral element contents in their yield, was eva- luated in this paper. Both biostimulation methods interacted in a different way towards chickling vetch seeds, causing the stimu- lation of different seed yield components. Radiation mainly affected the increase in total protein, crude fibre and mineral element (Na and K) levels. Nitragine treatment influenced the increase of calcium and microelement levels such as Zn and Cu. Single radiation of chickling vetch seeds caused an increase in the total protein level of all varieties of seed yields. Both biostimu- lation methods caused an increase of Fe in seed yield, but Mg con- tent was, in practice, at the same level in the majority of varieties under study.
