Influence of seed treatment with a magnetic field on sowing qualities and performance of spring barley

The article proposes an analysis of long-term studies to identify the effectiveness of the gradient magnetic field (GMF) on the growth and yield properties of spring barley. The experiments were carried out in Ryazan region of the Russian Federation on dark gray forest soils. According to the results of the experiments, it was revealed that the use of GMF for seed treatment before sowing contributed to an increase in the intensity of growth processes. Treatment of barley seeds before sowing with a gradient magnetic field, compared with the control, contributed to better plant survival and an increase in density by 2.2 %. In the variant with the use of a magnetic field, a higher volume of the photosynthetic apparatus was noted in all stages of the crop development compared to the variant without pre-sowing treatment. It was higher by an average of 17.14 % in the tillering stage and by 6.98 % in the booting stage. In the variant with seed treatment, barley plants were distinguished by an increased degree of tillering. On average, the maximum productivity was in the variant with pre-sowing seed treatment with GMF, where the increase in yield to the control values was 4.6 dt/ha or 12.7 %.
