Abstract. The effect of inert media (rockwool, perlite, expanded clay) and two levels of nutrient solution (EC-2.3 and EC-2.8) on the yield and mineral composition of greenhouse tomato cultivar ‘Cunero F1’ was investigated. The experiment showed no significant effect of medium and nutrient solution levels on the total and marketable yield of tomato fruits.
Key words:

The yielding and mineral composition of greenhouse tomato grown in inert media
Summary
In the experiment the effect of inert media (rockwool, perlite, expanded clay) and two levels of nutrient solution (EC-2.3 and EC-2.8) on the yield and mineral composition of greenhouse tomato cultivar ‘Cunero F1’ was investigated. In rockwool highest total (4.57 kg ∙ plant-1) and marketable (4.41 kg× plant-1) yield of tomato fruits was detected and lowest in expanded clay (4.43 kg ∙ plant-1 and 4.20 kg ∙ plant-1 respectively), but it was no significant differences. The research showed no significant effect of nutrient solution levels on the total and marketable yield of fruits. In tomato leafs higher potassium and sulphur content and lower nitrogen, calcium and magnesium concentration was observed by EC-2.8 nutrient solution, compared to EC-2.3 nutrient solution fertilizing.
