    The research was conducted in the years 2010–2011 at the Fruit Farming Laboratory of the West Pomeranian University of Technology in Szczecin. Two cultivars of grapevine were examined, Regent and Cabernet Sauvignon. The size of clusters and fruits, the content of extract and organic acid and juice yield of the grape must obtained were examined. The changes of grape must colour in the process of warm (20–22oC) and cold (7–10oC) maceration were evaluated. It was shown that the Regent cultivar was characterized by larger fruits. Grapes from this cultivar also had a higher content of organic acids, vitamin C and yielded more juice, compared to Cabernet Sauvignon fruits. However, a lower extract content was found in Regent cultivar fruits. It was also found that the temperature of grape must maceration affects its colour. The release of dark dye from grape skins occurred more rapidly during warm maceration. More substances which give wine its red colour were found in the grape must prepared from Cabernet Sauvignon fruits. The measurement performed on the last day of maceration of both cultivars under analysis, regardless of the temperature at which this process was conducted, revealed the highest value of the b* parameter which defines the blue colour.

    The field experiment was established in 2004 on the object of the University of Natural Sciences and Humanities in Siedlce. In the conducted experiment, the following factor was applied: mushroom’s substrate doses (0, 2, 4, 6 kg · m–2). In the study a commercially available grass mixture of Super gazon was used. On the all experimental objects mineral fertilization in the form of Pokon fertilizer was used. In each year of the study many characteristics were evaluated such as the general aspect, compactness, color and regrowth. Additionally, in the autumn of each study year the root biomass produced by the turf was determined. The value of all studied features of turf lawns has improved with increasing the doses of mushroom’s refuse and this refuses effected the turf compactness as the most favorable.Regardless of the mushroom’s refuse dose more favorable values of the studied features the turf lawns reached in the first year of the study, than in the second. It may indicate about weakening effect of the impact of used mushroom’s refuse in subsequent study years.
