abstract:
In pot experiments, hot pepper (Capsicum annuum L.) cultivar ‘Wulkan’ was grown in a substrate of mineral soil with raised peat (v:v = 3:2); potassium fertilizer type was differentiated using KCl, K2SO4 and KNO3. The effect of Cl-, NO3-, SO4-2 ions contained in the applied fertilizer on the salinity, as well as the effect of these anions on the chemical composition of leaves as the representative part were determined. Anions characteristic of the applied potassium fertilizer type dominated in the substrate of the given combination. In the stage of vegetative growth, using K2SO4, the highest concentration of SO4-2 was found which exceeded EC in the substrate. Plants fertilized with K2SO4 and KNO3 in the stage of vegetation growth contained more nitrogen in leaves in comparison with KCl nutrition.
