The effect of the aftereffect of the use of foliar top dressing on the elements of potato productivity is considered. In 2020-2023, the Kostroma Scientific Research Institute of Agriculture, a branch of the Federal State Budgetary Budgetary Institution «A.G. Lorkh Potato Research Center», conducted research on the effect of Borotem water-soluble fertilizer on the yield and quality of seed potatoes. In 2021-2023, an experiment was conducted to study the aftereffect of this fertilizer on plant growth and development. The experience was laid in the field crop rotation of LLC Minskoye in the Kostroma region of the Kostroma region. The purpose of the research is to analyze data on the effect of foliar fertilization with Borotem fertilizer in the aftereffect on the formation of the vegetative mass of potatoes. The soil of the experimental site is sod-podzolic, cultivated, medium loamy. The humus content is 1.25-1.5%, the pH is 4.35, the content of mobile phosphorus and exchangeable potassium is 459.3 and 115.4 mg/kg of soil, respectively. Agrotechnics of cultivation are standard for the Kostroma region. In the studies, potato varieties of domestic breeding of different ripeness groups were observed. 6 varieties of FGBNU «A.G. Lorch Potato Plant» were selected: early – Meteor, Zhukovsky early, Luck; middle–early - Cornflower, Handsome, Lukyanovsky. The results of studies conducted in the period from 2021 to 2023 are presented. During the growing season, biometric measurements of plants were carried out in order to identify the aftereffects of fertilizers. The set of economically valuable traits included the length and number of stems of plants. The area of the plot in the experiment was 10.9 m2, the repetition was threefold, and the location of the plots was systematic. The planting scheme is 70×26 cm, planting with a clone planter in cut ridges. According to the results of three years of research, an increase in the length of the stem and an increase in the number of stems in the bush relative to the control were observed in the experimental variants. The length of stems increased by an average of 1.7-7.4% over 3 years, and the number of stems increased by 8.3-19.5%.
Key words: potatoes, variety, foliar top dressing, aftereffect, length and number of stems
