The aim of the research was to analyze and evaluate both growth and physiological features of corn, cultivated in various solis and fertilised with sewage sludge. The present study investigates the effect of manuring on energy plant development, especially those cultivated on low-quality soils, and the usefulness of Phytotoxkit test in predicting the efficiency of such a treatment. Sand as well as various types of soil, e.g. sandy, peat or clay, were enriched with 10-15% doses of sewage sludge which, to a large extent, influenced the growth of plants. Moreover, their biomass and chlorophyll a and b content increased, and photosynthesis, membrane stability and RNase activity in leaves were considerably improved. As far as Phytotoxkit is concerned, it appears that it might be useful when predicting the development of fertilized plants.
