In 1986-90 a field experiment was carried out, in a private farm near Bydgoszcz, to examine the reaction of sugar beets grown on very light soil to sprinkling irrigation and nitrogen fertilizing. Thanks to sprinkling irrigation, root yields increased on the average from 25.9 to 45.7 t/ha (76.4 percent) and leaves yields from 17.4 to 24.8 t/ha (42.5 percent). The structure of the crop underwent very favourable changes as the weight of a single root increased by 76 percent, the share of the smallest fraction (to 150 g) lowered twelve times, and the share of the largest one increased by 78.5 percent. At the same time, sprinkling irrigation caused an increase of sugar content from 15.9 to 17.97 percent, and of roots dry matter from 21.36 to 23.11 percent. The contents of dry matters in leaves lowered from 17.68 to 17.56 percent. The optimum yield influencing dose in conditions of sprinkling irrigation was 150 kg of N for 1 ha
