USAGE OF AN INTENSE ELECTROMAGNETIC FIELD FOR PRE-SOWING TREATMENT OF OIL RADISH SEEDS

The paper presents data from a study of the effect of exogenous treatment with an intense electromagnetic field (EMF) on the germination of oil radish seeds (Raphanus sativus L. var. oleifera Metzg.). Description of the experimental stand for the studied electromagnetic seed treatment, methodology and results of experiments on treatment of oil radish seeds is presented. It has been shown that treatment of oil radish seeds (Raphanus sativus L. var. oleifera Metzg.) with an intense electromagnetic field for 2 seconds significantly stimulates the growth of roots and shoots, while having no pronounced effect on germination. Treatment of seeds with an intense electromagnetic field for 4 seconds increases the germination of the studied crop by 8 % and stimulates growth parameters. Thus, different exposures can be used for different purposes: a 2 second treatment to stimulate growth parameters, a 4 second treatment to stimulate germination. Data from measurements of the content of nitrogen oxides at the outlet of the reaction zone are presented. It was noted that the NOx content made 44 ppm, i. e. concentration of nitrogen oxides at the reactor outlet is 0.44 %. It was shown that the described method made it possible to increase the germination of seeds and the rate of their growth, and the sufficient seed treatment time was 2 seconds, while the use of traditional methods of seed treatment require 5 to 30 seconds. This significantly reduces the energy consumption for seed treatment process with an intense electromagnetic field in comparison with prototypes. The described technology makes it possible to improve the quality of electromagnetic treatment of oil radish seeds, increase productivity (by reducing processing time), and reduce specific energy costs (due to the higher efficiency of the technology compared to technologies that imple- ment a different method of generating EMF).
