Two celeriac cvs. Brillant and Diamant were grown at different calcium fertilization: 0, 100 and 200 kg Ca/ha. The content of calcium in celeriac roots increased by 11.6 and 16.3 percent after treating of subsequent doses of Ca in comparison with the control plants. After 5-month storage in the cold store roots of celeriac fertilized with 100 kg Ca/ha had 14.6 percent and that fertilized with 200 kg Ca/ha 33.3 percent less cavities in comparison with non-fertilized plants. The results of this experiment indicate that insufficient level of calcium in tissue may be one of the reason of cavities forming in celeriac
