PECULIARITIES OF THE USE OF INNOVATIVE GROWTH REGULATORS IN POTATO AND SOYBEAN CULTIVATION IN THE FOREST-STEPPE OF THE PRIOB'E AREA
The authors cited the results of comprehensive experiments on the application of innovative environmentally acceptable growth regulators on industrial crops: potatoes and soybeans. The experiments were conducted in 2019-2021 in the soil and climatic zone of the drained forest-steppe in the conditions of chernozem on potato varieties, Lyubava (early) and Tuleevsky (medium maturing), and soybean on grain Zolotistaya (early maturing). These experimental fields belong to the Educational and Experimental Farm "Praktik" of Novosibirsk Region and the Closed Joint-Stock Company Livestock Breeding Farming "Irmen" of Novosibirsk Region. The maximum photosynthetic performance of Novosil and Ecofus applied to potatoes and soybeans is up to 19 % compared to control. The authors of the study treated crops before sowing as well as on the shoots before the beginning of the phase of budding. The yield against the growth regulators used increased significantly by 21-24 % when Novosil and Ecofus were applied during seed treatment and when spraying vegetative plants before the phase of budding. It was statistically established that the potato yield depended on variety by 30 %, on growth regulators by 33, and on conditions of the year by 23 %.
