abstract:
The paper presents the results of research on the impact of variable magnetic field employed to stimulate seed-potato tubers on the volume of potato tuber (Solanum tuberosum) yield and its mass (g) and size (mm) structure. Sample size was 50 pieces of tubers, used in three replications. Solenoid generating variable magnetic field with induction values of 20 mT, 40 mT and 80 mT was used for the stimulation. Stimulation times for seed-potatoes were 5, 45, 450, 1500 and 3600 s, and exposure doses were 1146 kJm-3s, 4584 kJm-3s and 18335 kJm-3s. Field experiment was carried out using the corn-field method, with three replications. The results have unambiguously (statistically significantly) indicated a positive impact of seed-potato stimulation with variable magnetic field on the volume of total and commercial tuber yield, and its mass and size structure, with reference both to the employed magnetic inductions and the exposure doses.
