“…В Липецкой области появился опыт выращивания земляники садовой при искусственном освещении. Биохимический состав плодов земляники садовой зависит от сорта даже в большей степени, чем от минерального питания [5]. Реакция земляники на свет является сортоспецифичной [6].…”

The purpose of the study is to establish the effect of artificial ultraviolet lighting on the content of biolo-gically active substances in strawberry fruits using the example of the Asia variety, which is widely used in production. The study was conducted in 2019–2021 in the Lipetsk Region. Transplantation of strawberries under conditions of a growing season was carried out by already rooted adult bushes with a clod of earth. The water-air regime of the soil under artificial lighting conditions was similar to open ground. Under artificial lighting, garden strawberry plants of the Asia variety bloomed 10 days later, had a smaller fruit weight, and had a lower content of organic acids and dry soluble substances than under the sun. Plants accumulated the same amount of water-soluble pectin substances regardless of the nature of the lighting. The content of yellow coloring substances from the vitamin P group – flavonols, as well as binders from the same group – catechins in strawberry fruits did not depend on the nature of the lighting. Strawberry plants under ultraviolet light accumulated the same amount of ascorbic acid as under sunlight. Compared to sunlight under artificial ultraviolet, strawberry fruits contained the least amount of pigments, including carotenoids and β-carotene. A significantly higher level of pectin substances, anthocyanins, tannins and coloring substances, including tannin, in strawberries under sunlight was established in comparison with artificial ultraviolet. Regardless of the nature of lighting, strawberry plants had the same water content and pH of the fruits and accumulated the same amount of ascorbic acid, flavonols, catechins and water-soluble pectin substances.

Current approaches to land use and agricultural production are increasingly aimed at achieving high productivity through the use of crop rotation, siderites, integrated plant protection, minimized soil cultivation, microbiological fertilizers, and biological preparations. Modern microbiological preparations enhance the uptake of nitrogen and ash elements by plants, improving the rhizosphere of plants and the quality of strawberry fruit. Aim. To establish the effect of Extrasol applied using drip irrigation and various forms of mineral nitrogen fertilizers on the chemical composition of leaves and fruit of garden strawberry.Materials and methods. Garden strawberry plants of the Rusich and Troitskaya cultivars were treated with Extrasol and mineral fertilizers. Experiments were carried out in 2017–2020 at open-ground plots of the Federal Horticultural Center for Breeding, Agrotechnology and Nursery (Moscow Oblast). The experimental plots were characterized by soddy podzolic soils of medium-loam granulometric composition. Plant samples were analyzed using conventional methods. The experimental scheme consisted in the application of various nitrogen fertilizers (ammonium nitrate, urea, and ammonium sulfate) either in combination (2 mL/L of the working solution) or without Extrasol. Conclusions. In strawberry cv. Rusich, the use of ammonium nitrate increased the calcium content in plant leaves and decreased its content in fruit, which negatively affected the crop quality. Mineral fertilizers applied in combination with Extrasol increased the nitrogen content in leaves and fruit. The combined use of the amide form of nitrogen (urea) and Extrasol adversely affected the level of nitrates in cv. Troitskaya fruit. The use of fertigation and Extrasol reduced the amount of soluble dry substances in strawberry fruit.
