Abstract

The indicator of high and productive potato harvests is the use of new high-yielding varieties, effective planting material, proper provision of plants with useful substances, ensuring crop care, protection of plants from weeds, diseases and pests, maintaining optimal soil moisture during the growing season. One of the priority indicators that determine the low yield of potatoes in many areas of Ukraine, both favorable and unfavorable for potato growing, is the use of low-quality seed material that is affected by infectious phytopathogens. reproduction of healthy seed material is one of the main tasks of potato seed production. The use of biological preparations to stimulate the development of plants, increasing their endurance to negative environmental stimuli is relevant for the accelerated reproduction of such material. Thus, the purpose of the article is to study the effective technological aspects during the reproduction of pre-basic seed material of potatoes, which includes the use of the biological preparation Albit, in the conditions of the southwestern territory of the Forest Steppe of Ukraine. The article presents the results of studies of the influence of methods of application of the complex drug Albit on the formation of potato productivity in the process of reproduction of pre-basic seed material in the conditions of the southwestern part of the Forest Steppe of Ukraine. In the course of research, it was established that in order to achieve a high level of realization of the biological potential of the culture and product quality when growing pre-basic potato seed material, it is advisable to treat the tubers at planting with Albit 100 ml/t and to spray twice in the seedling and budding phases of vegetative plants with the drug in a dose of 50 ml/Ha
