Abstract

A pre-sowing electromagnetic treatment of cabbage standard dry seeds from variety Balkan was carried out in the AC corona discharge field. The full planned experiment 22 type was performed in four variants of treatment with selected values of controllable factors: voltage U=20 and 10 kV, duration of treatment τ=10 и 30 s and length of stay of sowing seeds to 33, 26, 19, 12 and 5 days. It was established that the variants with pre-sowing electromagnetic treatment in the AC corona discharge field have a different effect on the studied characters and positive and negative influences of stimulation and reduction of the character values were observed. In this investigation of interest were the τelectromagnetic treatments with U=20 kV and τττττ=30 s and U=20 kV and τττ=10 s in stay after seed treatment τ respectively 12 and 19 days that demonstrated the most significant effects to increase the cabbage weight and the yield from total and standard produce. In these expositions, the cabbage weight exceeded that of the control with 29-30 % as it was registered total and standard yield higher with 20-21 % and 24-27 % towards those obtained in the control variant. Considerable increase of the standard yield with 25 % was reported also in variant with treatment U=10 kV and ττττ=10 s and stay of the seeds for 12 days. A decrease of vegetation period with 5-7 days was observed in these variants of electromagnetic impact
