In course of the research there was studied the aspects of improving of technology of late-ripening potato (Solanum tuberosum) cultivation through the use of complex liquid fertilizer, growth regulators and microelements on a background of organic and mineral fertilizer system. The research was realized in the conditions of the Republic of Belarus in 2010-2011 on trial field of Belarus State Academy of Agriculture. As a result of realized research there were revealed that the highest crop yield of variety Atlant and the late varieties (41.7 t/ha) with high quality tubers (dry matter content - 22.56%, starch - 20.30%, collection of starch per unit of square - 8.37 t/ha, nitrates - 69.8 mg/kg) was obtained on the background of organic and mineral fertilizers (50 t/ha of semi-decomposed manure + N120P80K180) with additional foliar application on potato growing plants with liquid fertilizer complex at plant height 15-20 cm (4 l/ha) in the beginning phase of budding (4 l/ha).
