Development of a Biologized System for Accelerated Seed Breeding of Potato as a Factor of Preservation of Productivity and Improvement of Safety of Produced Products

The potato is one of the most versatile, accessible and at the same time widespread vegetable crops of the globe, and in particular of the Russian Federation. Today notable can be imagined without it. But despite the plasticity of the potato crop, there are still “white spots” in its production. With late and even return spring and early autumn frosts, the climatic features of Siberia significantly affect the crop’s growing season, preventing it from realising its full potential. Like that of many other crops, potato production is associated with seasonality, and there are often significant losses during cultivation and especially during storage. An important challenge is to protect plants during growth and development by applying innovative, environmentally friendly crop protection and stimulation products. Organomineral growth and development regulators were particularly popular. In the work schemes of application of perspective, organomineral growth regulators in conditions of forest-steppe of Western Siberia were tested and perfected. Their influence on the primary phases of growth and development of potatoes and their maturity, and their influence on biometrical parameters of plants, a phytosanitary condition of crops, a crop capacity, and its safety are established. On average, under the influence of growth regulators Epin-Extra and Zircon, the growing season is shortened by 3-5 days; the spread of diseases is reduced by 1.5-2 times; the yield increases to 8.3 tons per hectare. These studies are confirmed by the calculation of economic efficiency. Thus, the use of these growth regulators provides the level of profitability of production up to 252%.

The work aims to study the effectiveness of herbicides application on potato varieties of different ripeness groups in the conditions northern forest-steppe of the Novosibirsk Ob region. The authors obtained experimental data on leached chernozem in Novosibirsk district, Novosibirsk region, in 2017-2019. In their studies, the authors used common elements of potato cultivation tech- nology. The general background for potatoes in autumn fertiliser was applied at a dose of P60K90. Nitrogen fertilisers were used at a rate of 60 kg/ha in spring under pre-sowing cultivation. Herbicides Gezagard, Lazurit, Zenkor, Boxer, and mixtures of individual herbicides were applied before and after sprouting when potato plants were up to 12-14 cm high. Herbicides significantly reduced the infestation of potato varieties Lubava (early) and Tuleevsky (medium-season). The authors showed that the use of herbicides accelerated the processes of growth and development of potato varieties of two groups of ripeness. There was a significant increase in leaf area, photosynthetic potential, and 23-28% plant productivity. On a background of herbicides increase of yield by 30-35% is observed. There was an increase in the marketability of tubers by 10%. Used herbicides provided good quality and preservation of potato production. The authors note that the double application of herbicides Zenkor and Lazurit offers high rates of weed reduction. Thus yield and quality of presentation have high indicators. In tubers of potatoes, the residual quantity of herbicides is not detected. Application of herbicides economically and energetically practical. The level of profitability exceeds control 1,4 times on a background of double spraying by herbicides Zenkor and Lazurit.

In the article experience of application of various organomineral growth stimulants on potatoes in the conditions of forest-steppe of Western Siberia is stated. In the course of work, the authors used new perspective preparations whose application has an essential influence on growth, development, the structure of a crop, and potato productivity. As a result of work, it has been established, that organomineral growth stimulants slightly influence the duration of the vegetation period of potatoes (1-3 days). The authors found that the infestation and spread of diseases in potato crops depended to a greater extent on the conditions of the year and the preparations used, and to a lesser extent on the variety. On average, the overall degree of plant infestation on the treated background was 2-8 % lower compared to the control. The use of organomineral growth regulators has a positive effect on potato yields. The Epin-Extra preparation was the most effective, application of which provided up to 8.3 t/ha yield increase at tubers treatment, and up to 7.2 t/ha at vegetative plants treatment. The use of organomineral growth regulators does not have a significant impact on quality indicators of potatoes, as the difference between the variants was not more than 1 %.
