The productivity and economic efficiency of Eichhornia crassipes (Mart.) Solms growing in the natural and climatic conditions of Ukrainian Polissya

The article presents a theoretical generalization and a new scientific problem solving that is effective and economic technology of cultivation of aquatic macrophyte species E. crassipes under the conditions of Ukrainian Polissya. Highlights the performance of plant species water hyatsynt depending on the trophic level of reservoirs. Calculation methods established economic efficiency water hyatsynt growing in different environmental conditions of water bodies zones of Ukrainian Polissya. The results of observations of the ecological features of plant species E. crassipes, evaluated the possibility of cultivation, the optimum conditions and propagation of plants in natural water bodies. The results on the influence of water temperature and air pollution on growth and productivity of higher aquatic plant species Eichhornia crassipes (Mart.) Solms.

Key words: productivity, trophic level, Eichhornia crassipes, Polissya.
