Different environmental factors can cause changes in the elemental composition of plants. The research attempts to shift the focus from studying the effect of soil on the elemental composition of plants to assessing the impact of multifactorial ecological blocks on this index. Using the method of atomic absorption spectroscopy, the content K, Na, Ca, Mg, Fe, Zn, Cu, Mn, Co, Li was determined in the seeds of 5 accessions of a new for Russia crop − vigna (Vigna unguiculata) when growing plants in
