The purpose of this study was to characterize responses of rice cultivars ‘Debiut’, ‘Marshal’, ‘Lazuryt’, ‘Korsar’, ‘Vikont’, and ‘Ontario’ to fertilization in the southern steppe of Ukraine. The study was conducted in the experimental field of the Institute of Rice of NAAS of Ukraine in 2019-2021. It was found that rice yielded the most when double-fertilized at a dose of N120P30: cv. ‘Vikont’ yielded 11.27 t/ha, cv. ‘Korser’ - 9.62 t/ha, cv. ‘Lazuryt’ - 8.99 t/ha, cv. ‘Debiut’ - 7.06 t/ha, cv. ‘Marshal’ – 9.77 t/ha, and cv. ‘Ontario’ – 9.24 t/ha. Three agro-ecological types of cultivars (northern, temperate and southern) were distinguished.
