Abstract: Fertilizer usage is increasing worldwide and with that, a lot of environmental problems are being created. So it is becoming really important to avoid such problems, one of these alternatives could be sapropel. The aim of this work is to investigate effects of sapropel on wheat (Triticum aestivum L.), barley (Hordeum vulgare L.) and beans (Vicia faba L.) photosynthesis pigment content and fluorescence parameters. Plants were sown in 1 l pots with prepared substrate, 10 seeds each. There were investigated the effects of unfertilized soil (control) and different concentrations 2.2; 3.1 and 4 t/ha of sapropel on plants. Plants were grown in controlled environment conditions. Experiment lasted one month, at the end of the experiment the content of pigments was measured spectrophotometrically. Handy PEA chlorophyll fluorimeter was used for determination of chlorophyll fluorescence parameters. In wheat leaves the content of chlorophylls a+b increased more (r=0.94, p0.05). Content of carotenoids differed similarly to chlorophylls, i.e. by increasing sapropel concentration in growth substrate the content of carotenoids increased in wheat (r=0.87, p0.05). Parameter of II photosystem efficiency – Fv/Fm ratio increased significantly together with sapropel concentration increase in wheat r=0.97 (p0.05). With increasing sapropel concentration photosynthesis index (PI) for wheat had low rise (r=0.4; p>0.05)
