Studying the influence of treating potato seed tubers with hot fog of protective-stimulating preparations

Abstract

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.

The influence of pre-plant potato treatment on plant development

“…This contributes to inertial deposition of fine droplets of hot mist on potato tubers. In addition, the maximum heating of the potato surface occurs, that, on the one hand, promotes disinfection and, on the other hand, activates physiological processes in the tuber, thereby accelerating the germination of shoots [1]. Despite the high temperature of the hot mist, the heating of tubers occurs within one to two seconds, so their temperature increases by 1-2° C. The treatment time for tubers can be varied either by the speed of the conveyor, or by changing its angle of inclination.…”

“…The chlorophyll content in the leaves of potato plants was determined using "N-tester" device. The vegetative activity index NDVI was calculated by the device using expression (1) [8]: NDVI= P NIR -P RED P NIR +P RED (1) where РNIR is the reflection of the leaf in the near infrared region of the spectrum; РRED is the reflection of the leaf in the red region of the spectrum.…”

“…Recently, chemical and biological preparations have been used to disinfect seeds [1][2][3][4]. Moreover, they are treated directly when planting.…”

The influence of pre-plant treatment with hot mist of biopreparations on the quality of spring barley yield

“…Pre-plant treatment with hot mist has a complex effect on grain crops. It protects seeds from harmful microflora, promotes better assimilation of soil nutrients and stimulates the physiological development of plants [1][2][3][4][5]. The use of hot mist of biopreparations for pre-plant treatment improves the physiological effect due to additional heating and at the same time reduces the consumption of biopreparations by reducing the droplet size [1,6].…”

Photosynthetic activity and productivity of potato plants when using foliar dressings with complex micronutrients and humate

“…Potatoes are among the crops that intensively consume nutrients during growth and development due to a weakened root system and large tubers [1,2]. In the initial period of growth, potato plants experience the least demand for nutrients from the outside, since they receive all the necessary nutrition from the mother tuber.…”
