The purpose of the paper is to determine the impact of the species of energy crops on biomass yields and the possibility of their involvement in the reclamation of contaminated areas. This is especially important from the point of view of the rational use of land for energy crops cultivation. Methodology. The research object is the processes of growth and development of plants, the peculiarities of the yield formation of energy crops biomass depending on the species traits and growing conditions. The research subject is the following energy crops: Big Bluestem, Indiangrass and Columbus Grass as well as the plant biometric indicators, biomass yield and energy efficiency of biomass production of energy crops (2016-2020). The results of research showed the variability of biometric parameters of energy crops. Over the research years, the dry biomass yield of Indiangrass was 8.9 t/ha in the first year, 10.1 t/ha in the second year and 14.9 t/ha in the third year, Big Bluestem – varied within 4.4–9.3 t/ha. Columbus Grass dry biomass increased from 11.4 t/ha (1st year) to 14.9 t/ha (2nd year) to 18.0 t/ha (3rd year). The developed model for the creation of artificial phytocenoses will allow land reclamation using energy crops based on agroecological monitoring and justification when growing energy crops. Perennial cultivation of Columbus Grass and Indiangrass provided the highest coefficient of energy efficiency (at a level or more than 3.0), which is typical for average efficiency of biomass production. Therefore, Indiangrass and Columbus Grass are recommended to be grown in order to reclaim marginal lands and obtain sustainable plant raw materials. Big Bluestem is recommended to be grown only as a companion crop of stand of grass. Furthermore, energy crops must be cultivated on the basis of ecological and adaptive technology elements, taking into account the defined territorial conditions. For the conditions of Ukraine, this complex will make it possible to reduce the negative impact on the environment as well as to obtain the stable yields of various biomass for its further processing and energy conversion.

Biomass yield of microorganisms is important in applied microbiology since it is the ultimate factor determining the amount of product produced regardless of whether product is growth-linked or not. In the case of environmental microbiology the opposite is true and minimizing the biomass produced, or the sludge in the relevant jargon, often is the prime goal. In this paper, a unique means of manipulating the microbial biomass yield of a heterogeneous culture to fulfil either of the two goals is presented. 5.0 mgl−1 Ni(II) in the feed composition to a completely mixed, once- through, activated sludge was found to induce the observed biomass yield of the microbial culture developed from sewage. As compared with the base-line study without Ni(II), where the reactor received synthetic wastewater only, true biomass yield was found to have increased along with the increased decay constant with the net effect of lowering observed biomass yield drastically at lower dilution rates and increasing it over that observed in the base-line study at higher dilution rates. At 10.0 mgl−1 influent Ni(II) concentration the culture conditions almost reverted back to the base- line study and at 25 mgl−1 Ni(II) concentration a truly steady-state condition could not be attained.

Root To Shoot Ratio

The atomized nutrient solution droplet sizes and spraying intervals can impact the chemical properties of the nutrient solution, biomass yield, root-to-shoot ratio and nutrient uptake of aeroponically cultivated plants. In this study, four different nozzles having droplet sizes N1 = 11.24, N2 = 26.35, N3 = 17.38 and N4 = 4.89 µm were selected and misted at three nutrient solution spraying intervals of 30, 45 and 60 min, with a 5 min spraying time. The measured parameters were power of hydrogen (pH) and electrical conductivity (EC) values of the nutrient solution, shoot and root growth, ratio of roots to shoots (fresh and dry), biomass yield and nutrient uptake. The results indicated that the N1 presented significantly lower changes in chemical properties than those of N2, N3 and N4, resulting in stable lateral root growth and increased biomass yield. Also, the root-to-shoot ratio significantly increased with increasing spraying interval using N1 and N4 nozzles. The N1 nozzle also revealed a significant effect on the phosphorous, potassium and magnesium uptake by the plants misted at proposed nutrient solution spraying intervals. However, the ultrasonic nozzle showed a nonsignificant effect on all measured parameters with respect to spraying intervals. In the last, this research experiment validates the applicability of air-assisted nozzle (N1) misting at a 30-min spraying interval and 5 min of spraying time for the cultivation of butter-head lettuce in aeroponic systems.
