Cleaning of root and tuber crops, in particular potato tubers, from soil impurities and plant residues when they are excavated from the soil is an important and urgent problem in the agricultural industry. This article discusses a new construction of a vibrating spiral root and tuber cleaner and a new experimental setup that makes it possible to study the influence of the main structural and kinematic factors on the operation of a spiral type cleaner, as well as to substantiate its rational structural and kinematic parameters. The main constructional difference of the developed cleaner is that the technological process of cleaning root and tuber crops from soil and plant impurities is carried out by moving the heap with coils of cantilevered spiral springs rotating at a certain angular speed and forced oscillatory movements of the ends of the spiral springs themselves in the longitudinal-vertical plane. In this case, soil and plant impurities are effectively sifted not only through the separating gaps and coils of the spirals, but are also significantly destroyed due to oscillatory movements. At the same time, the root and tuber bodies are guaranteed to be transported by the spiral coils themselves towards the unloading conveyor. In the case of covering the spiral coils with a rubber coating, there is no damage to the bodies of root and tuberous crops. The article also presents the developed methodology for conducting a multifactorial experiment on cleaning root and tuber crops from soil impurities and plant residues.

This paper presents results of shoot culture of in vitro microtuberisation of potato. Were researched induction of callus and roots of shoot explants on seed varieties of potatoes like: Dido and Marabel and mercantile varieties of potatoes like: Agria BE and Agria SR.

During this research the initial explants – sprouts, further are transfer (passeges) to new nutrirent medium, fresh, with new hormonal composition. These explants transferred to the new fresh medium are called shoots.
