Yield and fruit quality of cucumber depend on such factors as plant cultivar, plant nutrition and the cultivation method. The presented paper contains results confirming the usefulness of rockwool and coconut fibre as well as the application of the fertigation system in cucumber growing. Studies on the growing of cucumber Onyks F1 cultivar were carried out in the years 2003–2005 in an unheated greenhouse. A two-factorial experiment was established. One experimental factor consisted in the fertigation control methods including Soltimer device and the starting tray. The other factor included substrate types: rockwool Agroban and coconut fibre Ceres. Plant distribution was 2 plants per one square metre. On the basis of the presented studies, it was found that greenhouse cucumber yielding was influenced by the frequency of nutrient supply, by climatic conditions in the given year and by the applied substrate type. The applied media of rockwool Agroban and coconut fibre Ceres did not exert any influence on plant yielding. On the other hand, a significant effect on the total and the marketable fruit yield was exerted by the cooperation between the fertigation control method and the substrate type.

Greenhouse cultivation of four cultivars of cherry tomato (Goldita, Faworita, Flavorino, Organza) on the substrates used for the second time (cocofibre and rockwool) did not show any differences in their yielding. Fruits obtained from cultivation on the cocofibre contained less dry matter and vitamin C. During the vegetation period some changes in fruit quality were observed. In the first weeks of fruiting more organic acids and less of vitamin C were observed in fruits. At the time of full fruiting (II period) the content of vitamin C was at its highest and at the same time the content of organic acids and dry matter at the lowest. At the end of vegetation (III period) fruits contained more dry matter and total sugars). Cultivars significantly differed in respect to yielding and fruit quality. The highest content of the investigated components was characteristic for Favorita and Goldita cultivars and the lowest for Organza. However, that cultivar produced the highest total and marketable yield.

The investigation was carried out in greenhouse with tomato cv. ’Cunero F₁’ grown in rockwool, peat and sand substrates with fertigation system without recirculation. In this research nutrient liquid with or without chlorine was tested. The experiment showed no significant differences on the total, marketable and unmarketable yield of plants fertilized nutrient liquid with or without chlorine. The highest yielding of tomato in rockwool, while lowest in sand substrates was detected. The higher weight of one tomato fruit in peat substrate, compare to sand, was observed. Both substrates and kind of potassium fertilizing had no significant effect on the number fruits per plant.
