Study of the effect of using electrical stimulation on the increase of potato yield

Abstract

Several studies have shown that electric stimulation improves germination, root growth, and disease resistance. Nonetheless, there is a scarcity of research on the effect of electric treatment on plant growth characteristics and quality. We investigated the effect of electric fields on three potato varieties (Santé, Quvonch-1650M, and Bahro-30), and also to confirm the results, seeds of the same variety were planted with and without electrical stimulation in the second experiment. Seed tubers were electrically stimulated during this study using hand-held equipment equipped with two ultraviolet emitters and an antenna (low-frequency radio impulse bio-stimulation). Studies have shown that pre-planting electrical stimulation of plants accelerates emergence of shoots of plants for 3-4 days depending on a grade. In addition, use of electrical stimulation had a positive effect on the growth of the plant. All studied varieties were taller by 4-5 cm and multi-stemmed, and 12-20 flowers were formed on one stem, which is 2-2.5 times more than in the control. In the second study stimulated each bush (one seed) gave an average of 813 grams, while 398 grams was observed in the control group. Conducted visual counts and serological analyzes showed that electrical stimulation of plants contributes not only to the reduction of infestation plants with viral diseases, but also the manifestation of symptoms of damage. The Kuvonch-1656M, in the studied variant, were affected by diseases 12%, while in the control variant this figure was 16%. Hidden virus infection of plants was 26% and 31%, respectively.
