INFLUENCE OF PRE-SOWING MAGNETIC STIMULATION OF SEEDS AND FERTILIZATION ON YIELD AND QUALITY OF SUGAR BEET ROOTS

In a field experiment with sugar beet in 2015, a magnetic field was used as a means of physical improvement of germination, growth and development of plants. The multifactorial experiment studied the influence of the variety (Primadonna Tadeusz), magnetic stimulation of 40 mT and control (without stimulation) and two variants of mineral fertilization (optimal based on the content of nutrients, and control without fertilization) on the results of selected plant parameters. During the growing season plant growth and development were monitored and measurements were made. The root and leaf yield, content of selected molasses compounds and sugar were determined. Observations carried out during the experiment showed a statistically significant effect of pre-sowing seeds stimulation with magnetic field and fertilization on the growth and development of plants and sugar content in the sugar beet roots. The most favorable values were obtained for the pre-sowing variant with magnetic field stimulation of 40 mT and optimal fertilization developed on the basis of nutrient content.
