The experiment with tomato ‘Cunero F1’ was held in a greenhouse
where plants with 23 fruit clusters were grown in substrate consisting of rye straw, wheat straw
and rockwool. A closed system of fertigation without re-circulation was applied. The plants grown on all
kinds of substrates were fertilized with the same nutrient. Usefulness of rye straw and wheat straw as
substrates for greenhouse tomato cultivation has been established. The comparison of the yield of plants
grown in straw with the yield of plants grown in rockwool showed no substantial difference. The content of
dry weight, vitamin C and sugars in fruit has been differentiated to a small extent. After 34-week vegetation
period (at the end of the experiment) about 70% of straw has been mineralized. In the period of vegetation
the content of mineral N, P, K, Ca, Mg, S-SO4 and the content of pH and EC
in the substrates tested have been differentiated only to a small extent.
