The article describes the results of experimental work to determine the susceptibility of potato tubers to diseases during storage in a complex vegetable storehouse with forced ventilation. The potato variety Gala was taken as an object of research. The research was carried out in JSC Uchkhoz “Uralets” of the Beloyarsk CD of the Sverdlovsk region within the framework of the state task of the Ministry of Agriculture of the Russian Federation reg. No. 121092300056-9. As a result of experimental work, it was found that cultivation technology elements: feeding area, use of fungicides and storage parameters influenced the manifestation of diseases of potato tubers. The main diseases of tubers during storage are late blight, skin necrosis, Rhizoctonia blight, Fusarium blight, ring rot. An inverse correlation was revealed between the feeding area and the degree of damage to potato tubers, that is, the smaller the feeding area, the greater the degree of damage to tubers by diseases. The use of the fungicides shirlan and infinito was effective and reduced the degree of damage to 2-3%, with 5-7% at the control. In general, it was noted that in a complex vegetable storehouse with forced ventilation in all experimental variants, regardless of the fungicide type, an increase in the feeding area during potato cultivation reduces the incidence of tubers during storage.

Abstract. The purpose. To study the effectiveness of a complex multicomponent organomineral fertilizer of prolonged action based on local man-made waste from the metallurgical industry and poultry farming and extracted sources of mineral nutrition for plants. Methods. The article presents data on the study of the effect of a new organomineral fertilizer on the growth, development and yield of spring barley. Phenological and biometric observations were carried out, yields were taken into account, and quality indicators of grain were determined: weight of 1000 seeds, nature and protein content. Results. It has been established that the use of an innovative mixed multicomponent organomineral fertilizer improves the growth and development of barley plants. So at doses of 60 and 90 kg of AD per 1 ha of nitrogen and phosphorus, the length of the plant stem increased to 6.78–6.84 cm, the number of grains per ear increased from 0.39 to 1.08 pcs. and their weight increased by 0.13–0.15 ha. The highest yield was obtained with NP (60) – 4.91 t/ha, which is significantly higher than the control variant. When applying the fertilizer, the grain quality indicators improved: the weight of 1000 seeds, the nature of the grain and the protein content in the grain. It is noted that the use of a new organomineral fertilizer at a dose of NP (60) increases the productivity and quality of products and is optimal for the cultivation of barley in the Middle Urals. Scientific novelty. For the first time in the Middle Urals, a new innovative product was created and tested – a combined, mixed multicomponent fertilizer for growing crops, application for a patent of the Russian Federation No. of the task number 122032200206-4.

A comprehensive scientific and technical project “Breeding and seed production of new domestic potato varieties of Ural breeding for various purposes” has been implemented on the territory of the Sverdlovsk Region since 2018. Customer: Breeding and seed-growing company “Uralsky Kartofel (Ural potato)”. Participants: Federal State Budgetary Institution of Higher Education “Ural State Agrarian University”, Ural Research Institute of Agriculture - branch of Federal State Budgetary Scientific Institution “Ural Federal Agrarian Research Center of the Ural branch of the Russian Academy of Sciences”, Joint Stock Company Agroindustrial Complex “Belorechenskiy”, Federal State Budgetary Institution of Higher Education “Ural State Agrarian University”. Based on the use of modern equipment for microclonal reproduction and diagnostics of pathogens using PCR analysis and robotic DNA technologies, the production of original, elite seed material of domestic (Ural) potato varieties has been established. During the period of the project implementation, new competitive potato varieties Terra and Alaska were registered. Laboratory and field studies were carried out and new data were obtained on the development of elements of the growing technology for elite seed potatoes on the basis of LLC BSC “Uralsky Kartofel” and JSC AIC “Belorechenskiy” [5,17]. The directions of further research on the development of technological regulations for seed production and the Ural technology of cultivation of original, elite and reproductive planting material are determined. The work was carried out within the framework of the subprogram “Development of potato breeding and seed production in the Russian Federation”.
