“…Researchers (Titarenko & Karpuk, 2022) determined that when growing a hybrid of sorghum Brigga, the best indicators of energy harvesting with grain were obtained on foliar fertiliser variants with microfertiliser Alpha-Grow-Extra, 2 L/ha in combination with the growth regulator Stimpo-116.72 GJ/ha. And for growing a Yutami sorghum hybrid with seeds on the application of foliar fertiliser with microfertiliser Alpha-Grow-Extra, in combination with both growth regulators, the minimum difference and maximum energy collection were obtained -134.58 and 134.39 GJ/ha.…”

The article presents the results of studies on the effect of sorghum bicolor seeds (Sorghum bicolor (L.)) Moench treatment with a mixture of the mycorrhizal biopreparation «Mycofriend» and the biologically active adsorbent «BM-nanobiochar» on germination energy and laboratory seed germination. The optimal doses of biological preparations «Mikofrend» and «BM-nanobiochar», which ensure the maximum sowing quality of seeds, have been established. The aim of the study is to establish the optimal dose of biochar and mycorrhizal biopreparation, which ensures the highest sowing quality of sorghum bicolor seeds. The subject of the research is sowing qualities of sorghum bicolor seeds, mycorrhizal biopreparation and biochar. The research methods were biological (conducting a laboratory experiment) and statistical (descriptive statistics, dispersion, correlation and regression analyses) ones. The research results showed that the use of «Micofrend» for the treatment of sorghum bicolor seeds at a dose of 3–6 g/kg increases the energy of seed germination to 88.63–88.00 % (control – 84.81 %) and laboratory germination to 90.69 % (control – 86.69 %). The use of biological preparation «BM-nanobiochar» at a dose of 3–6 g/kg provided an increased energy of seed germination to 88.75–87.81 % (control – 86.31 %) and laboratory germination to 90.44–90.63 % (control – 88.94 %). Increasing the dose of both tested biological preparations to 9 g/kg led to a deterioration of the sowing qualities of the seeds. In the experiment the highest germination energy (92.25 %) and laboratory germination (93.5 %) was observed when treating sorghum bicolor seeds with a mixture of «Micofrend» and «BM-nanobiochar» at a dose of 6 and 3 g/kg respectively. The lowest rate of germination energy (81.75 %) was observed in the control variant without seed treatment with biological preparations. A close curvilinear relationship (R2 =0.81–0.98) was established between the sowing qualities of sorghum bicolor seeds and the doses of biological preparations «Mycofriend» and «BM-nanobiochar». The presence of a close multiple correlation between the sowing quality of the seed and its treatment with biological preparations «Micofrend» and «BM-nanobiochar» (R=0.867) was proved. Key words: germination energy, laboratory germination, mycorrhizal preparation, biochar, sustainable development, climate agreement, green European course, bioenergy.

Sorghum (Sorghum bicolor L. (Moenh) is a technical, food, and fodder crop and can be used for various purposes, given its value, the acreage should be substantially expanded in Ukraine, and the elements of cultivation technology should be thoroughly examined. The purpose of the study was to determine the effect of the growth regulator on the photosynthetic productivity of sorghum in the conditions of the Right-Bank Forest-Steppe of Ukraine. The following methods were used in the study: field, measuring and weighing, mathematical, and statistical. The study was conducted in conditions of unstable moisture in the Right-Bank Forest-Steppe of Ukraine in 2016-2019. Based on the results of the study, it was determined that the use of a plant growth regulator affected photosynthetic productivity, namely, the leaf surface area, photosynthetic potential and net photosynthesis productivity. The indicators for the content of chlorophylls changed. Thus, the assimilation area of leaves reached a maximum with seed treatment and spraying of crops and amounted to 8.56 thousand m2 /ha during the tillering period, during the period of stem elongation – 29.6 thousand m2 /ha, during flowering and full ripeness – 40.32 and 4.97 thousand m2 /ha. Net photosynthetic productivity in the control was the lowest – 4.67 g/m2 , the use of a growth regulator on seeds and crops contributed to its increase by 0.27 and 0.79 g/m2 . With the treatment of seeds and crops, the net photosynthetic productivity was the highest and amounted to 6.12 g/m2 . The sum of chlorophylls a+b had the highest rates during the tasselling period and, depending on the experiment options, ranged from 4.36 to 5.35. The yield of grain and biomass also varied depending on the use of the preparation, and was the highest in the version with seed treatment and spraying of crops (7.1 and 35.9 t/ha). The close relationship between photosynthetic productivity and the yield of sorghum is also determined. The study can contribute to the widespread use of growth regulators in sorghum crops, ensure the full development of plants, and increase grain yields and biomass
