The effect of various concentrations of sulphates in the nutrient solutions (I - 200, II - 400, and III - 600 mg SO4(2-0/cubic dm) on sulphur content in plants as well as plant height and leaf area of tomato plants grown with nutrient film technique (NFT) were investigated. Total-S and S-SO4 levels were determined in the leaf blades of the upper, medium and lower plant parts, during 3 phases of tomato growth and also in the roots. The increase of sulphate concentration in the nutrient solution resulted in the increase of total-S and S-SO4 levels in all analysed plant parts, regardless of the growth phase. There were no significant effects of different SO4(2-) levels in the nutrient solution on tomato growth and leaf area
