| Tartalmi kivonat: | Renewable energy sources have an important place in most European countries, with a tendency to increase their share. Biomass deriving from agricultural production is used, besides other purposes, for the production of biogass which is then used to produce electricity or for heating. Solid residues, which remain after the passage of biomass through biogass plant, are still quite voluminous and contain significant amounts of nutrients. In this regard, we studied the effect of solid residues, remained after fermentation, on growth and photosynthesis of cucumber in a semi-controlled conditions. One part of the experiment was done with solid residues as they are, and another part with composted solid residues. Mineral elements were in part supplied by nutrient solution. Significantly higher biomass of cucumber shoots was obtained in the presence of composted solid residues. With increase in amount of added solid residues increased dry weight of cucumber shoots, regardless of additional supply of nutrients through nutrient solution. Similar results were recorded for total leaf area. |
