In the experiment with greenhouse tomato cv. Cunero F1 the effect of nutrient liquid with or without chlorine on the chemical composition of leaves and fruits was investigated. In research rockwool, peat and sand substrates with fertigation system was used. The experiment showed higher potassium, calcium, magnesium and chlorine leaves content in tomato fertilized nutrients liquid with chlorine. Kind of potassium fertilization had no significant effect on the chemical composition of tomato fruits. Lowest witamin C, total nitrogen and potassium content in fruits of tomato grown in sand substrate was detected, compared with peat and rockwool
