“…In addition to traditional mineral fertilizers and pesticides, modern potato growing technologies also include the use of new-generation organic preparations [1,2]. This optimizes nutrition, stimulates the growth and development of plants, increases resistance to harmful environmental factors and a number of pathogens, contributes to increasing potato yields and environmental safety of agrocenosis [4,5,6].…”

In biologized agricultural production, together with minimized chemical agents, promising preparations based on various subspecies of spore-forming bacteria are widely used. The aim of the study was to determine the effectiveness of the use of biological preparations of Kartofin (based on the Bacillus subtilis strain I5-12/23) and BisolbiSan, (based on the Bacillus subtilis strain h-13) according to the following indicators: – germination of tubers, plant growth and development, prevalence and development of diseases on plants, crop weight and its marketability. The results of the studies showed that pre-planting treatment of seed tubers with Kartofin and BisolbiSan biologics had a positive effect on the germination of potato tubers, increasing it by 6.3 – 8.7% compared to the control. Under field conditions they showed high biological effectiveness against pathogens of fungal diseases of potatoes: late blight (from 37.5% to 100%). Accounting for the total yield showed that the highest yield indicators were noted on the variant with the use of the biological preparation BisolbiSan – 38.4 t/ha (20.5% higher than the control variant).

The Russian Black Sea coast is a favorable region for peach cultivation. Nevertheless, the humid subtropical climate promotes the active development of one of the most harmful diseases of the crop, i. e. leaf curl (Taphrina deformans (Berk.) Tul). The main method of protecting peach is chemical. However, long-term use of fungicides entails a serious ecological burden on the agrocenosis and leads to the emergence of resistance in phytopathogens. Thus, analyzing the efficiency of preparations that increase the natural immunity of plants is a relevant area. In the experiment, we studied the impact of plant growth regulators with an immune-inducing effect applied once during the flower bud stage on peach resistance to leaf curl and crop yield. The research was carried out in 2022-2023 in peach plantations using standard methods. The efficiency of preparations controlling leafcurl was assessed against an average infection background (the disease development in the control was 33.4 % in 2022 and 24.8 % in 2023). Treatment with the standard (Delan, water-soluble granules (dithianon, 700 g/kg); Scor, emulsifiable concentrate (difenoconazole, 250 g/l)) reduced the intensity of disease development by 2.9-5.7 times. A single application of the growth regulators Albit, Zerebra Agro, and Stimmunol EF during the flower bud period enabled an increase in the biological efficiency of the protective measures against peach leaf curl at the peak of the disease development (May) by 58.6-74.3 % relative to the reference variant. Moreover, the crop yield grew by 37.7-57.9 %.

Annotation. The quality indicators of potato tubers (dry matter content, starch, nitrates and heavy metals) are greatly influenced by varietal characteristics, agricultural practices, soil and climatic conditions and many other factors, among which the level of mineral nutrition is of great importance. The article presents experimental data on the study of the effect of various doses of mineral fertilizers on potatoes in the conditions of the foothill zone of North Ossetia. The scientific novelty lies in the fact that in the agroecological conditions of North Ossetia on the soils of leached chernozem, the influence of various doses of mineral fertilizers on the productivity and quality of potatoes was studied. The objectives of the study included studying the effect of various doses of mineral fertilizers on the height and number of potato stalks per bush, starch content, dry matter, and potato yield. Research methods. Records and observations were carried out according to the generally accepted methods described in the “Educational and Methodological Guide for Conducting Research in Agronomy”. The experience was laid in threefold sequence. Determination of the quantitative content of vitamin C in potato tubers was carried out by the Tillmans method. According to the results of experimental data, the use of mineral fertilizers made it possible to obtain a high yield of potatoes, so the yield on the Sadon variety was 27.9, 28.2, 30.3 t/ha, and in the control variant – 27.7 t/ha. It has been established that mineral fertilizers under the same soil and weather conditions contributed to the different development of plants, so the height of the stems of potato plants of the Farn variety is by – 2.2, 11.5, 9.4 cm higher than in the control variant. The nutritional backgrounds of the zone did not have a significant effect on the number of years of stems, pieces, but contribute to the accumulation of starch. Mineral fertilizers contributed to an increase in the content of vitamin C in potato tubers from 11.2–12.5 mg/100 g. The highest accumulation of dry matter was noted in the Background 3 (N120P120K120) variant – 18.3 and 18.8 %.
