The use of low-frequency electromagnetic fields in presowing seed treatment is an effective method of increasing germination and increasing the productivity of plants. In the laboratory of seed farming and primary seed farming laboratory-field experiments were conducted on presowing treatment of pea, barley and spring wheat seeds with an electromagnetic field of low frequency (EMF). For the study, we took a variety of peas − Pharaoh, barley − Ataman and spring wheat − Daria. In the laboratory, the treated seeds were germinated in sand and rolls of filter paper. Sowing of the treated seeds was carried out at the optimum time. The registration area of the plot is 10 m2, the repetition is sixfold. During the vegetation of plants, samples were taken and counts of the green mass and the weight of the root system were carried out. The dynamics of plant growth has been studied, and a structural analysis of the selected samples has been carried out. The harvesting of the plots was carried out by direct combining, the harvest was taken into account from each plot. Untreated seeds were taken for control of the experiment. It has been established that the application of low-frequency electromagnetic field on seeds increases germination energy and laboratory germination of treated pea, barley and spring wheat seeds by 2-4%, increases the length of seedlings of pea seeds by 6,7-22,2%, barley-7,2-20,3% and spring wheat 12,5-28,6%, their weight from 7,3 to 26,1%. Seeds t
reated with an electromagnetic field increase the height of pea plants from 9,3 to 17,7%, barley and spring wheat from 5,4 to 21,6%. The increase in the accumulation of green mass by pea plants amounted to a control variant-21,3%, barley-13,0%, spring wheat-29,4%. Field germination of treated pea seeds exceeded control by 6%, barley −by 5% and spring wheat − by 4%. The increase in pea yield amounted to a control – 0,22 t / ha (8,5%), barley – 0,27 t/ha (9,7%), spring wheat – 0,25 t/ha (8,4% ). An increase in the productivity of pea plants from 7,6 to 9,7%, barley and spring wheat from 5,9 to 10,2%, and an increase in the weight of 1000 seeds by 1,5-4,5% was noted
