The effects of KCl, K2SO4 and KNO~ on the yields of greenhouse tomatoes variety 'Revermun' cultivated on a peat substrate were examined. On the basis of fruit yield, dry weight content in the fruit and the content of K, Ca, Mg, Cl, S-SO4 in the soil and of N, P, K, Ca, Mg, Cl, S-SO4, Fe, Cu, Mn, Zn, Mo in leaf stalks it was found that KCl is the best form foir fertilizing greenhouse tomatoes cultivated on peat. No adverse effects of chlorine at concentrations of 1500 mg Cl/liter peat and 6,0% Cl in the dry mass of tomato leaves were observed
