Article gives results of studies with three varieties of potatoes: early Tiras, middle Slovianka and Zabava which were planted during summer on drop irrigation. Three backgrounds were used in researches: without fertilizer (control); N90P90K90 on the top of the soil; N45P45K45 locally in 0?12 cm soil layer. Also modern growth regulators: diazofitom, adaptofitom and agrostimulin were used during plants budding. Established that it is advisable to grow potatoes all grades, taken in the study of culture for summer planting and drip irrigation in southern Ukraine. Performance of bubbles formed substantially constant and depends on the background power. Due to fertilizer regardless of dose and method of making tuber yields increased by 43?45 %. The use of growth regulators contributes to further increase productivity. Investigated dose of fertilizer N90P90K90 on the top of the soil and N45P45K45 locally in 0?12 cm soil layer form the same productivity level. Dosage and ways of fertilization and application of growth regulators positively affect the quality of tubers of potato varieties. Processing potato plants early budding growth regulators contributed to further increase the solids content, starch and vitamin C in tubers as without fertilizers and their application.
