The aim of this work was to determine the effect of the type of substrates (rockwool and coir straw - Cocovita) on the yield and quality of tomato fruits. The experiments were carried out in the spring-summer cycles of 1998-1999 with 7 tomato cultivars: Delfine, Frontero, Marfa, Marissa, Megana, Raissa, and Recento. The results showed that higher yields (total, marketable, and early) of tomato were obtained when grown on rockwool than on Cocovita. Tomato cultivars varied in yield. The lowest yields were observed from ‘Delfine’.

Significantly lower yields of fruits were obtained from ‘Delfine’, ‘Marfa’, ‘Megana’, and ‘Raissa’ grown on Cocovita than on rockwool. The average weight of fruits of all tomato cultivars was lower when grown on Cocovita. However, the type of substrate had no distinct effect on the content of sugars and vitamin C, but tomatoes grown on Cocovita contained fewer mineral elements. Fruits from plants grown on Cocovita contained more dry matter than those grown on rockwool.
