Opis:
The aim of the study was to examine reproductive and vegetative responses of ‘Growdena F1’ tomatoes (Solanum lycopersicum L.) to use of potassium silicate fertilizer (as Silvit 15.0% SiO3) into reused peat substrate. Investigations were carried out at a greenhouse in 2013 and 2014. Tomatoes were treated with potassium silicate 2 times: immediately after tomato planting and a month later, at a rate of 0.11 g silicon (Si) per plant per year. Potassium silicate was applied as 1% water solution during plant irrigation. In each term, 200 ml Silvit of Si-containing solution per plant was applied. Plants unsupplied with potassium silicate serves as the control. The results showed that application of potassium silicate was able to improve tomato root healthiness, but only in the second year of the study, when the presence of pathogens in the tested substrate was high. The increases in marketable and total fruit yields as a result of use of potassium silicate was found only in 2014. It is concluded that at high multiplication of root pathogens in the substrate, the application of Sicontaining fertilizers do not protect sufficiently roots against infection.

Cunero F1 cultivar
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:
Gasification biochar represents one of the biochar types tested for agricultural needs. The aim of this study was to clarify the physico-chemical and biological changes occurring in a peat-sand substrate amended with hardwood-derived gasification biochar in the rates of 2, 4 and 20 g l-1. The pH(H2O) of the substrate with 4 g l-1 and 20 g l-1 biochar was increased from 5.6 to 6.2 and 6.7, respectively. The testing of the substrate in the re- spirometry device showed that the increase in the biochar rate led to a decrease in the amount of CO2 evolved at the maximum pressure drop. The continuous decrease in pressure observed in the respirometry bottles filled with pure biochar allows explaining this effect by biochar sorption activity. Addition of 2 and 4 g l-1 biochar to the peat-sand substrate stimulated the growth of cucumbers in an 18-day pot vegetation experiment. An increase in the number of root tips and root volume with a decreasing average root diameter was shown in the presence of biochar. Stimulation of plant growth on the background of low rates of biochar requires a further study with emphasis on the specific combination of biochar, soil type, plant species, and climatic conditions.

Opis:
The objective of this study was to evaluate the peat and zeolite mixtures substrates performance on cucumber seedling quality and crop yield. The research was carried out in a greenhouse covered with double polymeric film at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry. Cucumber seedlings were grown in different substrates: peat, peat + zeolite 1 : 1, peat + zeolite 2 : 1, peat + zeolite 3 : 1 and peat + zeolite 4 : 1. Cucumber seedlings grown in peat and zeolite substrates are shorter; the leaf area is smaller than that of the seedlings grown in peat alone. The dry mass of the aboveground part of these seedlings is lower (insignificant difference), however, the root mass is higher than those grown in peat alone. The addition of zeolite to peat substrate does not have any positive effect on the photosynthesis pigment content in cucumber seedling leaves. The physiological growth indices of the seedlings grown in peat-zeolite substrates were lower compared to those grown in peat. When zeolite is added to peat substrate, net assimilation rate is higher compared to those grown in peat. Higher yields (significant difference) were demonstrated by cucumbers, the seedlings of which had been grown in peat-zeolite substrates.

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.
