Technology of potato cultivation including tubers treatment by protective and stimulative preparations, tillage of various soil depth, creation of volume potato drills with rational soil density, treatment of potato plants by protective and stimulative preparations and new agricultural machines and working equipment parts destined for technological operations and technologies at potato cultivation is adduced. Laboratory and field experimentations and industrial tests have confirmed that the technology of potato cultivation with row - spacing 0,9 m (without crop increase), including the use of cultivator KGO - 3,6, in comparison with the traditional technology (a row - spacing 0,7 m) has the following advantages: the expense of fuel has decreased up to 10% (to 0,65 kg/ha); expenses of work have decreased on 18% (up to 12 man-hour/ha); quality of soil crumbling has improved on 10 – 12%; volume mass of potato drill has decreased on 7 - 9%; the area of cross - section section of drill has increased to 0,09 - 0,12 m; the water and air regime of soil in drill is stabilized; soil density in a zone of tube nest has decreased due to removal of a trace of wheels of a tractor from the last one; the number of row - spacings on hectare, including junction, has decreased; weeds in a protective zone has efficiently choked due to their filling up; the quantity of passes of machines across the field (planting, for interrow processing and harvest) is reduced to 28%; productivity of the machines has increased at interrow processings on 8 – 10%; marketability of tubers has raised on 7 - 9% (due to reduction of tubers become green)
