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.
Tabbacco wastes, coffee production wastes, cocoa shells and their mixtures exerted the positive influence on total and marketable yields of carrot's roots in comparison with manure. Organic materials (investigated factors) did not have clear influence on the nutrient value (dry matter, total sugar, carotenoides) of carrot. Roots of carrot which were fertilized by Polifoska (mineral fertilizer) and coffee production wastes bail contened the least nitrates of all. Visibly had occured differences in quanlity and qantity among years. Tabacco wastes, coffee production wastes, cocoa shells and their mixtures can be use in fertilizing of carrot.
W pracy określono wpływ fertygacji na wielkość i jakość plonu owoców malin odmian powtarzających w warunkach plantacji produkcyjnej. Badaniami objęto dwie odmiany malin: `Polana` i `Polka` rosnące na towarowej plantacji o powierzchni 2,20 ha. Zastosowano dwa schematy nawożenia: kontrolny i program Yara. Jakość owoców określano na podstawie: masy 100 owoców, strat masy owoców podczas przechowywania i oceny cech mechanicznych owoców. Uzyskane wyniki wskazują na celowość stosowania fertygacji w uprawie malin powtarzających. Intensywnie sterowane nawożenie stymulowało wzrost roślin co z kolei zwiększyło wielkość i jakość plonu.
