The cultivation of energy crops is an important component of renewable bioenergy, which pursues the goal of reducing greenhouse gas emissions and determines the effective management of fertility and land use of marginal lands and disturbed areas of various nature. As a result of the conducted research, convincing relationships were established between the application of sewage sludge with a compensatory dose of mineral fertilizers and the productivity of grassy energy crops. The greatest increase in green mass is provided by the application of SS (SS - 40 t/ha + N10P14K58) for all studied crops. applying sewage sludge with the addition of mineral fertilizers is an effective way to increase the productivity of green mass by 57-64% for such energy crops as Jerusalem artichoke, Silphium perfoliatum L, Miscanthus giganteus, and switchgrass (Panicum virgatum L).
