The effect of different rates of potassium: 0.4; 0.8; 1.2; 1.6 g K ∙ dm-3, and calcium carbonate: 5 g and 15 g CaCO3 ∙ dm-3, on stalk celery yield and vitamin C content as well as on salt concentration in the medium was analysed in a greenhouse experiment. Stalk celery weight and vitamin C content were found to be reduced after the application of the potassium rate higher than 1.2 g K ∙ dm-3. The study found that the salt concentration in the medium increased with an increase in the rate of potassium and that there was no effect of the increased rate of calcium carbonate on total salt concentration in the medium of stalk celery. The different rates of calcium carbonate affected the uptake of nitrogen, phosphorus, and magnesium by stalk celery.
