Influence of humic preparations on the development of honeysuckle in the forest steppe of Western Siberia

Abstract

Blue honeysuckle is a winter-hardy and unpretentious crop; in folk medicine, its berries and juice are used for hypertension, anemia, and intestinal disorders. The environmental situation and the general rise in prices of pesticides and mineral fertilizers stimulate the choice of alternative technologies and the use of biological plant protection products, growth stimulants, and bacterial fertilizers. In this regard, our research aimed to study the effect of various humic preparations on the growth and development of green cuttings of blue honeysuckle variety Berel. This variety has a medium ripening period, gives a high yield, is slightly crumbling, and is highly winter-hardy. The research was carried out in the Novosibirsk region on the territory of the Agro Seed Company in 2019 - 2021. The average annual growth and general condition of blue honeysuckle plants of the Berel variety were determined according to generally accepted methods. Data analysis showed that all studied indicators of honeysuckle plants are greatly influenced by the year’s conditions when the difference between years reaches 25 - 30%. In addition, it was found that all the studied drugs positively affect the growth and development of plants and, in particular, the survival rate and overwintering of green honeysuckle cuttings (up to 45%). Thus, the ZhT “Ekozhizn” preparation provided better survival and overwintering of plants. Cytohumate had a better effect on the development of vegetative mass, but in terms of survival and overwintering, it was inferior to using the ZhT “Ecozhizn” preparation.
