Abstract. The findings on fruits crop of shrubs of Rosa rugosa useful to biological reclamation of ash landfills are presented in this paper. The scientific research was carried out on the model of reclamation of ashes and organic wastes located on grounds ZE “Dolna Odra” S.A. in Nowe Czarnowo in 2005-2006 years. It was found, that the height and quality of crop of all the examined objects have parameters with statistically important differences. Taking into consideration all the examined parameters of crop the best results were received in the place with ash fertilizing NPK and cover making from bark, sand, compost, and ash. The research is continued.

The estimation of fruits crop of romanas rose (Rosa rugosa) cultivated on the burner wastes reclaimed
with an application of different methods

Summary

The biological reclamation of burner wastes landfills, narrows their specific physical and chemical property – especially alkaline reaction pH 9-12, and is a big problem. Small habitat requirements and alkaline resistance of romanas rose suggest that shrubs of this species are helpful for reclamation. Rosa has edible fruits, willingly cropping and used in processing. The studies on top and quality of fruits crop were necessary. The scientific research was carried out on the fruit cropping from shrubs growing on ashes preparation by two methods with five covers. The influence of the methods on top of crop, fruit mass and dry matter, vitamin C, extract and nitrate content of fruits were examined.

Used organic matter to arable layers had important influence on the examined parameters. Fruit crops and contents of vitamin C in juice on all objects were comparable or higher than the parameters presented in the literature. Substratum from ash fertilizing NPK and cover made from bark, sand, compost and digested sludge were the best for top and quality of fruit crop. The research did not include examination of toxic elements such as heavy metals or radioelements so they were not sufficient to recommend for consumption of rose fruits from shrubs growing on the ashes.
