Opis:: 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.
Badania przeprowadzono z pomidorem szklarniowym odmiany ‘Cunero F₁’ uprawianym w wełnie mineralnej, torfie i piasku z wykorzystaniem kroplowego systemu fertygacji, bez recyrkulacji pożywki. W badaniach zastosowano pożywkę z chlorem (KNO₃ + KH₂PO₄+ KCl) oraz bezchlorkową (KNO₃ + KH₂PO₄+ K₂SO₄) . Nie wykazano istotnych różnic w plonie ogólnym, handlowym oraz plonie owoców poza wyborem pomidora nawożonego pożywką zawierającą chlor i bezchlorkową. Niezależnie od rodzaju nawożenia potasowego najwyższy plon ogólny oraz handlowy wykazano w uprawie roślin w wełnie mineralnej, natomiast istotnie najniższy w piasku. Większą masą jednostkową cechowały się owoce pomidora uprawianego w torfie oraz w wełnie mineralnej. Nie stwierdzono istotnego wpływu badanych czynników na średnią liczbę owoców z rośliny.

Opis:: The hydroponic system is very often used for greenhouse vegetable production. The flood irrigation on a bench or on the flood floors is applied in the production of ornamental plants and vegetable transplants. This system is environmentally friendly, since fertigation is used in a closed system using the recirculation of nutrient solution. The aim of this study, conducted in 2010-2012, was to determine the effect of flood fertigation with different concentrations of nutrient solution (EC: 1.0; 2.0; 3.0; 4.0 mS cm-1) on the yield and quality of the butterhead lettuce cultivar Natalia grown in different substrates (coconut coir, peat and rockwool). The experiment was conducted in the spring and autumn cycle. The highest marketable yield at each concentration of the nutrient solution was achieved in the cultivation in rockwool, both within the spring and autumn. The highest nitrate content in lettuce in terms of both cultivation cycles was found in the lettuce grown in the nutrient solution concentration of EC 4 mS cm-1, and the lowest one was achieved in the nutrient solution concentration of EC 1.0 mS cm -1. Significantly less of nitrates was in lettuce grown in spring than in autumn. Higher levels of EC significantly increased the content of P and K in lettuce leaves during in both growing cycles, while the content of Ca and Mg was not significantly different. The applied substrates had a significant impact on the content of K, P, Ca and Mg in leaves of lettuce. The best concentration of the nutrient solution used for flood fertigation of greenhouse lettuce was EC 3.0 mS cm-1 for the spring cultivation and EC 4.0 mS cm-1 for the fall crop.

Opis:: The effectiveness of different peat-based substrates was compared for the propagation of two mountain tree species (silver fir and European beech). The experiment was set up in spring of 2006, and seedlings were grown in polystyrene multipots for 2 years. Four types of substrate were applied: (1) newly prepared 1:1 peat-sawdust mixture ; (2) a peat-sawdust mixture which had already been used for five production periods; (3) a peat substrate produced in the ‘Nêdza’ container nursery (Rudy Raciborskie Forest District), consisting of peat and perlite; (4) a peat substrate, as described for (3), with added mycorrhizal fungus Hebeloma crustuliniforme. After sowing, polystyrene multi-pots were placed in a transparent tent. During the autumns of 2006 and 2007, for both species and each substrate type, 25 seedlings were randomly selected for measurement of their above-ground height, root length, root collar diameter, above- and below-ground fresh weight. Growth of one-year old and two-year-old seedlings of both species differed depending on their substrate. The application of a mycorrhizal inoculum positively affected seedling establishment, since the best height growth and largest seedlings of both species were grown on substrate (4). The growth of one-year-old fir seedlings in the ‘old’ peat and sawdust mixture (2) was similar to those seedlings on the turf substrate (3). Root:shoot allocation differed among the substrates. In fir root:shoot allocation was approximately equivalent at 1:0.9, whereas for beech it was 1:2 in oneyear-old seedlings and 1:1.5 in two-year-old seedlings.
