Abstract: The modern system of nursery management of strawberry should be aimed at the use of adaptive cultivars and clones, allowing to obtain high yields of high-quality products. Optimization of mineral nutrition of plants, the use of plant growth regulators are necessary for the modern management of plant repositories, including strawberry. The study of ways to increase the yield of planting material of strawberry due to the simultaneous inhibition of the formation of peduncles is an urgent task in uterine plantings of the highest quality categories. The purpose of the research: to study the effectiveness of ways to reduce the components of generative productivity and increase the yield of planting material of strawberry garden varieties of short daylight hours and neutral daylight hours. In a field agrochemical experiment with plant growth regulators and doses of nitrogen fertilizer in the Stupinsky district of the Moscow region, on sod-podzolic soils, strawberry cv. Lubava, Tsaritsa, Nashe Podmoscov’e, Polka were studied. Doses of nitrogen fertilizer: N = 80 kg/ha and 120 kg/ha. Plant growth regulators: chlormequat chloride and gibberellic acid (GC3). As a result of the first year of research, it was found that the use of plant growth regulators and an increased dose of nitrogen in the strawberry cultivar of neutral day (Lyubava) contributed to a decrease in generative productivity, but also caused a decrease in the number of outlets. In shortday strawberry plants, a cultivar-specific reaction to fertilizer doses and plant growth regulators was observed, as a result of which it was revealed that the nitrogen dose N 80 kg /ha contributes to an increase in the generative productivity of plants cv. Nashe Podmoskov’e to a greater extent than cv. Polka and cv.Tsaritsa.
