Popis: At the moment, a new technique is often used in the technology of potato production and that is pre-treatment of seed material, which is done with the help of chemical, biological and physical methods in complex. Stimulation of plants in the initial period of the growing season requires a special approach. On the one hand, plants need nutrients and, on the other hand, they do not have a developed root system for their production. Therefore, foliar treatment of plants with protective stimulating preparations is an alternative to fertilizer application. Potassium mobilizing bacteria are able to mobilize potassium present in the soil in the root zone of plants. Liquid fertilizers based on humic acids are natural immunomodulators and stimulators of the formation, growth and development of plants, as well as antidepressants and complex nutrition additive. They are suitable for organic farming. Potato seedes were treated with hot fog of protective stimulants at temperatures from 40° C to 60° C immediately before planting. As a result of the studies, the effects of protective-stimulating preparations on plant biometry during the growing season (accumulation of aerial mass) and yield were studied. Hot fog treatment of potato seed tubers with POTASSIUM HUMATE and AZOTOVIT preparations showed the best dynamics of increasing the height of shoots of potato bushes, which exceeded the control by 5.3% and 8.2%. Pre-treatment of potato seed tubers with hot fog of protective-stimulating preparations is an effective method of increasing productivity and it contributes to better products.
