Field trials in Europe with Miscanthus over the past 25 years have demonstrated that interspecies hybrids such as M. 9 giganteus (M 9 g) combine both high yield potentials and low inputs in a wide range of soils and climates. Miscanthus hybrids are expected to play a major role in the provision of perennial lignocellulosic biomass across much of Europe as part of a lower carbon economy. However, even with favourable policies in some European countries, uptake has been slow. M 9 g, as a sterile clone, can only be propagated vegetatively, which leads to high establishment costs and low multiplication rates. Consequently, a decade ago, a strategic decision to develop rapidly multiplied seeded hybrids was taken. To make progress on this goal, we have (1) harnessed Correspondence: John Clifton-

The article deals with the main methods of nutrient removal from wastewater, as well as presents promising technologies and techniques. Struvite was characterized by a complex phosphorus fertilizer. The influence of struvite on the processes of germination of cultivated plants was investigated. The possibility of creating a growth substrate as an inexpensive and effective alternative to the disposal of the man-made wastes that contain an organic component was identified. The composition of the growth substrate was selected to ensure its functional properties. The growth substrate was tested by bioindication. Subsequently, the modification of the substrate by adding natural sorbents.

The article presents the results of research of growth processes and anatomical indicators of wheat culture of the variety Kraevid, depending on the treatment with the growth-regulating preparation – tebuconazole (0,5% and 1%). The tebuconazole was treated by spraying the aerial part and introduction through the root system. It has been established that the use of tebuconazole of different physiological-active concentrations (1% and 0.5%) in different methods of introducing into the plant (through the root and through spraying) led to a slowing of linear growth and inhibition of the root growth of wheat plants. The most distinct effect was observed with the use of 1% tebuconazole when the retardant was treated through the root. Treatment of wheat plants with tebuconazole through root and spraying caused significant changes in water metabolism and photosynthesis of plants: the linear size of stomata decreased, that led to reduction of the stomata area. It was found that when the tebuconazole was fed through the root, the transpiration intensity was higher than in the variant with the spraying of plants.
