In order to obtain maximum yield, ensure the quality of the resulting crop, as well as reduce production costs, researchers are currently attracted to various methods of stimulating plant growth and development, without which it is impossible to imagine modern crop cultivation. The use of growth regulators is one of the effective factors in the formation of highly productive crops of field crops. Epin-Extra and Agate-25 Super are among the most popular preparations. An increase in the production of a valuable crop of jerusalem artichoke, due to the improvement of its cultivation technology with the help of these preparations, can become a source of an increase in environment friendly feed. In this regard, the aim of the research was to study the effect of drugs on the development and provision of a stable and high-quality Jerusalem artichoke crop. In the conditions of unstable moistening of the forest-steppe of the Middle Volga region, a research was carried out to study the features of plant formation and yield of Jerusalem artichoke of the Skorospelka variety under the influence of tuber treatment, non-root treatment and complex treatment of tubers with double foliar treatment of plants with growth regulators Epin-Extra, Agate-25 Super. The experience was laid on the collection site of the Penza State Agrarian University in 2020-2022 on meadow-chernozem soil according to generally accepted methods. Because of the growth regulator application, the indicators of the elements of the structure of the tuber harvest increased in relation to the control. The height of plants varied from 165 to 187.6 cm, the largest mass of aboveground part was 911.5 g, of tubers 1237.1 g, average yield was 22.58 t/ha. The Skorospelka variety is well adapted for growing tubers in the conditions of the Middle Volga region. Effective and environmentally safe methods of increasing yields and improving the quality of Jerusalem artichoke are the treatment of tubers before planting, followed by double foliar fertilization of plants with growth regulators. An increase in yield is observed on average by 5.16 t/ha, the predominance of the share of large tubers by 43.78%.
