The actual issue of modern digitalization of the development of the fishery complex of the Russian Federation is the cardinal transformation of economic, scientific, technical, legal, production technological, production relations with digital platforms. The fishery complex as one of the important and integral parts of the country’s economy, providing the population with food and forming food security of the state, the main consumers of the products of most interrelated sectors in technological, economic and organizational fields of the economy. Intensive use and consumption of natural resources in order to maintain human civilization due to the limited nature of these resources cannot develop without proper regulation, both at the federal and regional levels. “Sustainable” fishery is a guarantor of food security of any country, and digitalization is essential.

The main challenge of modern land management is the need to increase the yield of cultivated crops, while maintaining quality, minimising total energy inputs into cultivation and minimising the negative impact on the environment. This is quite possible if we have healthy seeds characterised, first of all, by improved sowing qualities. In order to realise the mentioned approaches, it is possible to use seed preparation for sowing, using for this purpose various electrophysical effects, including treatment of seed material in the electric field of high voltage. The purpose of the presented article is to analyse the results obtained to study the process of treatment of cereal seeds before sowing in the electric field of constant and alternating high voltage, as well as the electric field of pulsed high-voltage discharges. A universal experimental laboratory setup was assembled for the research. According to the results of the experiments, there was a clear dependence of the speed and friendliness of germination of winter triticale and barley seeds on the effects of electrical nature on them. Efficiency of such influences is also shown in plant protection against various pests, so against bread fleas and meromysa it is treatment in the electric field of alternating high voltage with duration of 120 s, as well as against Swedish fly, but with duration of treatment of 60 s; against wheat thrips – in the electric field of constant high voltage with duration of 60 s. Besides optimisation of phytosanitary condition of crops, the stimulating effect of high voltage electric field on yield structure of cereal crops (winter barley and triticale) was revealed, as productivity increases, bushiness and more dense productive stalks are formed. Electrostimulation has a positive effect on such hard-to-regulate parameter as ear fineness – the total number of grains in the ear increases by 13.8…31.0%; the weight of 1000 grains slightly increases – by 3.0…6.2%; grain yield to total weight increases by 40.3…57.8%; positive effect on all elements of yield structure is traced.

The research was conducted to study the influence of electrophysical effects on melon seeds and their development, as well as to identify the most effective variant of pre-sowing stimulation and treatment mode. As an agro-technological task, we evaluated the possibility of realising the development potential inherent in the seeds of melon plants, which could be realised using electrical stimulation, with minimal negative impact on the ecology of the environment. To study the effect of high voltage electric fields (DC, AC, pulse) on gourd seeds before sowing, a specially assembled setup was used. Treatment of pumpkin seeds in the electric field of constant high voltage showed that on the 3rd day there were 100% of germinated seeds, in the electric field of variable high voltage – 50%, in the electric field of pulsed high voltage – 30%, pumpkin seedling in the treatment in the electric field of constant high voltage was longer in 9.0 and 3.6 times than in the control and other treatments; treatment of watermelon seeds in the electric field of constant high voltage showed that on the 3rd day there were 70 % of germinated seeds, in the electric field of variable high voltage – 20 %, in the electric field of pulse high voltage – 40 %; watermelon germ at treatment of seeds in the electric field of constant high voltage was longer in 1,5…2,0 times than in the control and other treatments.2.0 times longer than in other treatments. High effect on the destruction of pathogenic microorganisms was observed when seeds were treated in the electric field of pulsed high voltage – the number of pathogenic microorganisms on the seed coat of watermelon and pumpkin was 4.25 and 4.1 times lower compared to the control; when treated in the electric field of constant high voltage, their number was also 3.0 times less, but the treatment of seeds in the electric field of alternating high voltage recorded an increase in pathogenic microflora in 2.0 and 1.2 times. The highest yields of watermelon and pumpkin were obtained with pre-sowing seed treatment in the electric field of constant high voltage – by 25.5 and 37.8 %; in the field of alternating voltage – by 15.7 and 27.0 %; in the field of pulse voltage – by 9.8 and 5.4 %.
