“…Exposure of plant tissue to high voltage pulses is also accompanied by high temperature, visible and ultraviolet radiation, high electric and magnetic fields, high electric current density, ultrasound, pressure at the shock wave front, and ionization processes [19,20]. The predominance of one or another factor depends on the parameters of the electrical impulse, the properties of the plant tissue and is of a random probabilistic nature.…”

This article considers the theoretical foundations of the electropulse effect on plant objects. The influence of the energy absorbed by a living system on the degree of damage to plant cells and tissues is studied. It has been established that the impact of many damaging factors accompanying a high-voltage electrical impulse determines the degree of damage to plant tissue. The authors propose to consider the process of electrical processing from the standpoint of the law of conservation of energy and accept the initial conditions that describe the properties of a plant object. However, the research results do not allow theoretically assessing the dependence of the coefficients included in the formulas on all the parameters that determine their values.

Abstract. Seeds of five Bulgarian cotton varieties, stored for one and two years, were subjected to five pre-sowing electromagnetic treatments with different intensity and duration of exposure. It was found that the selected values of controllable factors had stimulating effect on the total length and total mass of sprout and root. The total length of sprout and root increased by 7.5-16.4% (p<0.05), the total mass of sprout and root increased by 7.8-12.7% (p<0.05). The best treatment options were 1[U=(8…5)kV, τ =(15…35)s] and 4[U=(6…3)kV, τ =(5…25)s]. Electromagnetic treatments had stronger positive effect on seeds stored for one year. Compared to the untreated control, corresponding to each storage period, the electromagnetic impact had stimulating effect for both storage periods: for the total length of sprout and root the increase was by 7.6-21.1% and 2.3-11.0% at option 4; for the total mass of sprout and root it was by 10.8-16.5% at option 1 and 4.5-9.1% at option 4, respectively, at one-year and two-year storage of seeds. In comparison with the control Chirpan-539 variety, untreated seeds, one-year storage, higher values for both studied characteristics were found only for seeds stored for one-year: for the total length of root and sprout at the varieties Natalia, treatment options 1 and 4, Nelina and Helius, options 2 and 4 and Chirpan-539, option 1; for the total mass of root and sprout at the varieties Nelina, options 1, 2 and 3 and Chirpan-539, option 5. Compared to the untreated control corresponding to each variety, the stimulating effect of the pre-sowing electromagnetic treatment for the two characteristics was found for all varieties, for both storage periods. The Helius variety was the most responsive to the electromagnetic impact, with the strongest stimulating effect for both characteristics, at the one-year storage of seeds the total length of sprout and root increased most strongly by 34.8-43.9% at options 1, 4 and 2[U=(6…3)kV, τ =(15…35)s], and the total mass of sprout and root increased by 48.5% at options 1.

The production and cultivation of new high-quality seed varieties are linked to the sowing of various crops with diverse physical and mechanical seed properties. Efficient seed-metering unit operation is critical during the technological process of fodder crop cultivation, predominantly when sowing non-free-flowing seeds. The quality of seed sowing and crop yield significantly rely on the design precision of seed-metering devices, technical maintenance and appropriate calibration. A rotary seed metering device was incorporated to ensure that non-friable seeds are uniformly sown, thus maintaining consistent seed supply and consumption at all stages of circulation. The study of the proposed device's productivity dependence on its operating parameters is justified because these variables affect crucial indicators such as the capacity to achieve and sustain the desired seeding rate over the entire operational duration. The study presents findings from an experimental investigation on sowing non-free-flowing (non-flowing) and finely dispersed seeds using a rotor seed-metering unit. The tests aimed to ascertain the precision and evenness of sowing such crops. It was observed that the speed of rotation of the seed-metering unit's vane disk is a key factor in the uniformity and supply of sown seeds. The limits of variation in rotor rotation speed and rotor seed-metering unit productivity per second were established to guarantee the desired seeding rate for various crops, including alfalfa, Agropyron, and Bromus inermis.
