Краткий осмотр (реферат): Main task of feed production is to provide farm animals with nutrients. Insufficient or excessive intake of these elements can lead to undesirable consequences. For instance, a deficiency in mineral elements reduces the protective function of the animal's body against various diseases and disrupts the functional activity of organs. Conversely, an excess of any element contributes to the expenditure of a significant amount of energy for its removal and, in some cases, leads to poisoning. Imbalanced animal feeding results in decreased productivity and a deterioration in the quality of products, leading to the production of non-viable offspring and a disruption of reproductive capacity. Our calculations have shown that increasing the energy concentration in the diet from 490 to 600 EFU/kg DM, combined with an increase in feed intake by 4.4 kg, ensures proportional energy consumption based on their productivity difference. In our research, we concluded that it is economically advantageous to use the planned norms of the nutrient requirements for cattle in feed planning.

Краткий осмотр (реферат): The current state of the essential oil industry in Ukraine requires the expansion of areas for essential oil crops. Nowadays, the demand for natural vegetable raw materials and lavender essential oil is growing. Therefore, the aim of the research was to study the morpho-biological features and productivity of lavender plants by treatment with plant growth regulators Radostim and Stimpo during the third-fifth years of the growing season in the Southern Steppe of Ukraine. The research was conducted during 2018–2020. The material for the research work was lavender plants such as Lavandula angustifolia Mill., the varieties of Sinieva and Vdala. The field experiment was done with the method of split randomized blocks. The research was accompanied by phenological, biometric, structural and laboratory observations in accordance with generally accepted methods. Treatment with the growth regulator Stimpo has the greatest stimulating effect on the processes of growth and productivity in lavender plants. Using this method, the highest yield was formed in all years of vegetation from 6.70 to 7.90 t ha-1 at standard humidity, which is by 14.8–21.1% more than in the control. The mass fraction of essential oil in vegetable raw materials is quite high (1.85–2.32%), it differs in lavender varieties and does not depend on treatment with plant growth regulators. The largest harvest of essential oil in all years of vegetation was obtained by treating plants with the growth regulator Stimpo from 137.30 up to 147.36 kg ha-1, which is by 15.9–16.7% more than in the control.

Краткий осмотр (реферат): Ukraine faces the joint challenge of energy independence and resilience of supply. Frequent power outages have serious consequences for people, businesses and the economy, but renewable energy sources can mitigate this problem. Assessment of Ukraine’s energy system and the potential impact of renewable energy sources on power outages suggests that further diversification of energy sources into renewables will be affordable and efficient, provide a more stable and independent energy supply, and allow for more decentralised distribution of electricity.

Краткий осмотр (реферат): he purpose of the research is to determine the duration of the interphase period, total water consumption, plant height, yield and quality of sunflower seeds, depending on the characteristics of hybrids and foliar top dressing with microfertilizers. Methods. Experimental studies were conducted during 2020–2021 in the experimental field of Mykolaiv National Agrarian University (Ukraine). Results. It was determined that all the studied microfertil-izers extended the duration of interfacial periods of sunflower plants. The largest total water consumption of sunflower plants (2259 m3/ha) was formed in the hybrid NK Kamen in the variant with foliar top dressing with microfertilizer Quantum, which was 0.9–6.5% more than in the same variant with hybrids Darius and Tutti. The highest height of sunflower plants among the hybrids submitted for study was formed by Darius – 165.7–170.9 cm, which was 5.0–5.7% higher than the height of plants of the NK Kamen hybrid and 7.2–8.0% more than the height of Tutti hybrid. It was found that the highest yield of sunflower seeds (2.55 t/ha) on average over the years of research was formed in the hybrid NK Kamen in the variant with foliar top dressing with microfertilizer Quan-tum, which exceeded its level in the non-fertilized control by 18.6% and the average yield for all variants of the experiment by 12.3%. The highest yield of sunflower seeds (2.56 t/ha) among the hybrids submitted for study was provided by NK Kamen in 2021, which was 12.3% more than in the Darius hybrid and 6.6% more than in the Tutti hybrid. Foliar top dressing with microfertilizers significantly affected the quality indicators of seeds of the studied sunflower hybrids. The maximum fat content values (from 50.1 up to 52.7%, depending on the hybrid) were achieved by applying Quantum microfertilizer in the 5-6-leaf phase. The conditional yield of oil from seeds in this variant of nutrition is also determined to be the maximum – from 1.13 up to 1.34 t/ha, depending on the hybrid. Less effective for the growth and development of plants and the formation of their productivity was the preparation Rostok, with the introduction of which the duration of the growing season increased by 1-2 days; total water consumption increased by 29–35 m3/ha; the height increased by 1.1–4.6 cm; seed yield increased by 0.80–0.28 t/ ha; the content fat in seeds increased by 0.02–0.03%; oil seed yield increased by 0.12–0.15 t/ha. © 2024, Polskie Towarzystwo Inzynierii Ekologicznej (PTIE).
