A study was conducted to determine the effectiveness of using various doses and modes of pre-sowing electron irradiation of barley of the Vladimir variety as a way to improve the quality and quantity of grain crops. A vegetation experiment was carried out, as a result of which the following crop parameters were evaluated: the height of plants with an ear, the total number of stems, the number of productive stems, the mass of straw, the mass of 1000 grains and crop productivity. New information has been obtained on the formation of biological effects in agricultural crops under the influence of various modes and doses of electronic radiation on its seeds.
