Abstract: Field tests were carried out after performed pre-sowing electric (electromagnetic and electrostatic) treatment of wheat seeds of the varieties Enola and Kristy. It was confirmed that the used helical device for pre-sowing electromagnetic treatment could contribute to an environmentally friendly and energy efficient increase of yields of the wheat varieties Enola and Kristy.
Variety dependence was established of both wheat varieties to the pre-sowing electric treatment of their seeds, the controllable factors being the voltage between the electrodes and the duration of treatment. At certain voltage levels, for both types of electric treatment – electromagnetic and electrostatic - a decrease in the yield of the studied varieties was recorded within the range of (1-5)%. Under different levels of the controllable impact factors, after the electromagnetic and electrostatic pre-sowing treatment a possibility was achieved to increase the grain yield of the wheat variety Enola within the range of (105.7-579.7) kg.ha-1, and of the variety Kristy – within the range of (172.9-226.4) kg.ha-1. The studies of the pre-sowing electric treatment of wheat seeds were carried out in the period (2010-2012).
