The article deals with the issues of establishing the possibility of cultivating non-traditional sweet potato crops in the region. Based on the results, source materials were selected, their involvement in breeding work, and high-yielding, early-ripening, adaptive varieties were bred - Sochakinur, Toyloki, Branch, which is included in the State Register. Wide cultivation of selected varieties in the main crop on April 20-30 according to the breeding scheme of 70x25x1 and 90x20x1 cm by mulching with a film, maintaining the irrigation regime during the growing season of plants according to the pre-field soil moisture of at least 70- 80% of the FPV and fertilization at the rate of N200P160K100 kg/ha contributes to obtaining a high yield (50 t/ha and above) with good commercial qualities. And in the re-culture, planting seedlings on June 20-30 provides opportunities for obtaining a crop within 35-40 t/ha.
