The experiment included a variant of sprinkling irrigation and a non-irrigated control variant. The fertilization variants included four levels of nitrogen nutrition (90, 120, 150, 180 kg/ha), and a variant with the preparation Betafiksin (90 kg N + Betafiksin/ha). Root yield of irrigated sugarbeets were significantly higher than those in the non-irrigated control (99.74 vs. 87.26 t/ha). The average yield increase due to irrigation practices was 12.48 t/ha or 14.3%. The highest root yield (102.20 t/ha) was obtained in the variant with 150 kg N/ha. This yield was highly significant in relation to the yields obtained with 90 and 120 kg N/ha, and significant in relation to the yield obtained with 180 kg N/ha. The application of Betafiksin resulted in highly significant yield increases in relation to the variants with 90 kg N/ha both with and without irrigation. Highly significant differences were registered in the sugar content between the irrigated and non-irrigated variants (15.12% and 15.98%, respectively). The fertilization variants with 90 and 120 kg N/ha had highly significant or significant sugar contents in relation to the variants with 150 and 180 kg N/ha regardless of the water supply. Both variants of Betafiksin application, irrigated and non-irrigated, had higher contents than the fertilization variants with 150 and 180 kg/ha.
