In Ukraine, grain sorghum is an important grain crop used in bioethanol and solid fuel production. It stands out signifcantly from other grain crops by its economically valuable features, drought resistance, high productivity and universality of use. Grain sorghum is grown for use in the food industry (the main processed products are sorghum starch, glucosefructose syrups, alcohol, etc.), in fodder production and, more recently, in the energy industry. Therefore, the research of the elements of the cultivation technology, namely the sowing time and the depth of planting of grain sorghum seeds, is expedient and perspective. The article highlights the research results of the influence of the sowing time and the depth of planting seeds on the energy productivity of sorghum crops of the grain varieties ‘Dniprovskyi 39’ and ‘Vinets’ in the Right-Bank ForestSteppe of Ukraine. The purpose of the research is to establish the optimal sowing time and the depth of planting of grain sorghum seeds and to substantiate their influence on the crop energy productivity in condition of the Right-Bank Forest-Steppe of Ukraine. The research was conducted during 2016–2020 at the Bilotserkivska Research Station of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Sciences of Ukraine. It was found that the highest crop yield was obtained by sowing grain sorghum seeds in the 1st decade of May at a planting depth of 4–6 cm. At the same time, the grain yield of the ‘Dniprovskyi 39’ variety was 7.1–7.4 t/ha, of the ‘Vinets’ variety – 6.3–6.7 t/ha; the yield of biomass of the ‘Dniprovskyi 39’ variety was 40.2–44.4 t/ha, of the ‘Vinets’ variety – 37.3–39.5 t/ha. The highest bioethanol yield was obtained by sowing grain sorghum seeds in the 1st decade of May at a depth of planting of seeds of 4–6 cm. Cultivation of the ‘Dniprovskyi 39’ variety allowed to obtain 2.37–2.47 t/ha of bioethanol, the ‘Vinets’ variety – 2.08–2,21 t/ha. The yield of solid biofuel in this variant of the experiment was also the largest and amounted to 9.29–10.26 t/ha for the ‘Dniprovskyi 39’ variety and 8.62–9.12 t/ha for the ‘Vinets’ variety. The total energy yield from the obtained biofuel of the ‘Dniprovskyi 39’ variety was 210.66–228.98 GJ/ha, of the ‘Vinets’ variety – 192.37–203.95 GJ/ha.

Grain sorghum is one of the most highly productive multipurpose grain crops for food, feeding and technical purposes. Considering this, the research of the elements of the technology of grain sorghum growing is expedient and high-potential. The article presents the research results of the influence of the sowing time and the depth of planting seeds on the phenological observations, field germination of seeds, biometric indicators of sorghum plants of the grain varieties Dniprovskyi 39 and Vinets in the Right-Bank Forest-Steppe of Ukraine. The aim of the research is to establish the optimal sowing time and the depth of planting seeds of the grain sorghum varieties, to substantiate their influence on the characteristics of plant growth and development in the conditions of the RightBank Forest-Steppe of Ukraine. The research was conducted during 2016–2020 in the conditions of the Bilotserkivska RAS of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Sciences of Ukraine. It is proved that the sowing time and the depth of seeding have a significant impact on the growth and development of the grain sorghum plants. It is established that at the 1st decade of May and to the planting depth of 4–6 cm the grain sorghum seeds vegetative season reduces and equates 108 for the Dniprovskyi variety, and 105 days for the Vinets variety. Sowing seeds at the 3rd decade of April and the 2nd decade of May, as well as decreasing the planting depth to 2 cm and increasing to 8 cm, lengthens the grain sorghum vegetative season of the researched varieties. Field germination reached its maximum in grain sorghum seeds sowing at the 1st decade of May and to the planting depth of 4–6 cm and equals to 84.2–86.8 % for the Dniprovskyi 39 variety and 83.1–85.4 % for the Vinets variety. Biometric indicators that affect the formation of crop productivity, namely, plant height, bushiness, stem diameter, were maximum in the same variant of the experiment.

Due to global climate change, sugar sorghum (Sorghum saccharatum), due to its fast growth rate, early maturation, efcient use of water and limited need for fertilizers, is the most promising plant for biofuel production in the world. The article presents the results of the study on establishing the dependence of sugar sorghum energy performance indicators on varietal characteristics (varieties 'Silosne 42' and 'Favorit' and hybrids 'Dovista' and 'Medoviy F1') and the green biomass harvesting time. The purpose of the research was to establish the influence of varietal characteristics and harvesting time on sugar sorghum energy productivity in the zone of unstable moisture in the Central part of the Forest-Steppe of Ukraine. The research subject is sugar sorghum energy productivity indicators (yield of green biomass; sugar content of juice; yield of biogas, bioethanol, solid biofuel; total energy yield). The studies were carried out during 2016–2020 in the zone of unstable moisture in the central part of the Forest-Steppe of Ukraine in the conditions of the Bila Tserkva Experimental Breeding Station of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Sciences of Ukraine. It has been established that the highest yield of biofuel and energy (up to 791.8 GJ/ha) is achieved under growing sugar sorghum of the 'Dovista' hybrid, provided that its biomass is collected in the phase of full seed ripeness (early October). It is advisable to start collecting sugar sorghum biomass for biogas after the panicle throwing phase. To ensure the maximum yield of bioethanol, the optimal time for harvesting green biomass of sugar sorghum is the second decade of September – the frst decade of October. The maximum yield of solid biofuel is achieved under harvesting biomass after the phase of waxy ripeness of grain. The formation of the yield of green biomass of sugar sorghum was more influenced by weather conditions (47.4 %), the influence of varietal characteristics (17.8 %) and the timing of harvesting (12.8 %) was less. But the energy yield was most influenced by the timing of harvesting biomass (37.4 %). A close linear correlation between the energy output and the yield of green (R2=0.81) and dry biomass (R2=0.99) was established. The most ecological plasticity in terms of the total energy yield per unit area turned out to be the 'Medoviy F1' hybrid (b=1.62), which indicates the prospects of growing this hybrid under favorable weather conditions and high level of agricultural technology. Key words: sugar sorghum, varietal characteristics, harvesting time, energy yield, biofuel yield, productivity.

The article presents the results of studies of the influence of elements of cultivation technology on the yield of grain sorghum. Purpose. To investigate the influence of row spacing and plant density of sorghum plants of grain varieties Dnіprovsky 39 and Vіnets on the formation of indicators of the structure of crop yields in the conditions of the Right-Bank Forest-Steppe of Ukraine. Methods.Field, laboratory, comparative, analysis, generalizing, mathematical and statistical. Results. It has been proven that the best results in the formation of elements of the structure of the yield of grain sorghum were obtained when sowing seeds with a row spacing of 45 cm and a density of 150-200 thousand pieces/ha. With this sowing method, the panicle length was the largest and was equal to 28.5 – 29.9 cm in the Dniprovsky 39 variety and 28.3 – 28.2 cm in the Vinets variety, the panicle weight was 51.5 – 55.1 g in the Dniprovsky variety 39 and 54.8 – 55.4 g for the Vinets variety. The number of seeds in a panicle and their weight, depending on the increase in plant density from 150 to 250 thousand pieces/ha, decreased and the variety Dniprovsky 39 was from 1623 to 1592 pieces/panicle, and the grain weight per panicle was from 44.3 to 47.1 g. In the Vinets variety, the number of seeds decreased from 1536 to 1512 pieces/panicle, and their weight from 49.3 to 47.7 g. However, the weight of 1000 seeds was the highest at a plant density of 200 thousand pieces/ha and a row spacing of 45 cm and is equal to 31.2 g for the Dniprovsky 39 variety and 27.8 g for the Vinets variety. The grain yield in the same variant of the experiment is the highest and is 7.4 t/ha for the Dniprovskiy 39 variety and 5.1 t/ha for the Vinets variety. It should be noted that a decrease in the row spacing to 15 cm and an increase to 70 cm led to a decrease in these indicators. Conclusions. It has been established that the best formation of the elements of the yield structure of grain sorghum is observed when sowing seeds with a row spacing of 45 cm and a plant density of 200 thousand units/ha, which we recommend for growing this crop in the Right-Bank Forest-Steppe of Ukraine.

Обґрунтування менеджменту посівів проса прутоподібного (світчграсу), за встановлення найбільш впливових агрозаходів на урожайність, є актуальним питанням (для удосконалення елементів технології вирощування), що потребує детального вивчення. Визначено, що залежно від схем передпосівної підготовки ґрунту найбільша урожайність світчграсу (від 12,3 до 15,5 т/га) зафіксована при проведенні двох культивацій навесні з коткуванням ґрунту до- і після сівби на фоні напівпарового осіннього обробітку ґрунту. Збільшення кількості культивацій у весняний період не має впливу на продуктивність культури. За роки проведення досліджень кращими варіантами виявилося вирощування світчграсу з шириною міжряддя 45 см і застосування весняного підживлення рослин нормою азоту 30-45 кг/га. Внесення зменшених та збільшених норм азоту не призводить до суттєвого підвищення урожайності, а й навіть зменшує даний показник. Поряд з цим, на варіантах із більш ширшими міжряддями – 60 см істотної різниці між внесенням N45 і N60 не виявлено. Найбільшу урожайність світчграсу отримали за норми висіву насіння 3,0 млн. н./га, як зменшення, так і збільшення даного показника призводить до зниження продуктивності культури. В той же час, порівняно із ранньо-, пізньовесняними та літніми строками сівби відмічено збільшення урожайності культури при весняному строкові сівби. Alternative resource of energy crops (including switchgrass) involvement to fuel and energy complex of Ukraine is a critical problem at present. Energy crops’ sowings management increases yield and oil equivalent output within the certain area of energy crop plot of land. That is why determination of the most influencing agrotechnological techniques (for cultivation technology elements improvement) over switchgrass yield is an important issue and requires a more complicated study. Research purpose is to determine switchgrass yield depending upon complex application of the cultivation technology elements. The agricultural experimental methods as well as proper theoretical and practical recommendations of switchgrass cultivation given by Wolter Elbersen, M. V. Roik, V. L. Kurylo and other scientists have been used in order to lay out the experiment and perform multiple-factor researches in the Forest-Steppe area. Obtained research results have been processed by application of Statistics computer programs. Change of switchgrass yield depending upon schemes of pre-sowing soil tillage has been observed. Switchgrass yield varied according to years in the range from 2.4 to 14.7 tons per hectare (1 cultivation), from 7.4 to 14.6 tons per hectare (2 cultivations), from 7.7 to 15.0 tons per hectare (2 cultivations and rolling) with general autumn soil tillage. Substantially higher indices have been provided on the options with semi-steam soil tillage, change of yield on the options according to the years was: option 1 – from 5.8 tо 14.4 tons per hectare, option 2 – from 10.8 to 14.7 tons per hectare and option 3 – from 12.3 to 15.5 tons per hectare. Dynamic of switchgrass yield growth applying nitrogen additional fertilizing and increasing the area of plant nutrition with optimal sowing term has been fixing within the experiment years. The best option was the option of switchgrass cultivation with row-spacing of 45 cm and application of spring additional fertilizing with dosing of 45 kg/ha. Applying less or bigger nitrogen dosing does not cause considerable yield increase, but even lessens this index except option with row-spacing of 15 cm and nitrogen application of 60 kg per hectare. It can be explained by plant competition for nutrients while growing them on narrow row-spacings and needs in higher nitrogen dosing. Although, there was not huge difference between application of N45 and N60 on the options with wider row-spacing of 60 cm. The maximum productivity the switchgrass depending on the sowing time was 3.0 million seeds on hectares. It is determined that the decrease, and an increase in this indicator leads to a decrease in crop productivity. Substantial influence of spring agrotechnological techniques performed before crop sowing process on the background of general and semi-steam soil tillage in autumn has been discovered on the basis of multivariate connection between the experiment options and yield of switchgrass dry biomass. Also, it has been established that the method of soil tillage as well as nitrogen additional fertilizing in spring had more significant influence on switchgrass yield.

Nowadays pea and soybeans prevail in agrocoenosis among legume in the Right-bank Forest-steppe. In contrast to these crops, the chickpea is more drought-resistant at the same time, it does not lodge, and the beans do not crack when ripe. In this regard, the problem of developing the elements of chickpea cultivation technology becomes important, in particular, the selection of effective measures to protect crops from weeds using herbicides. It is possible to reduce and overcome herbicide stress when using biological preparation of natural origin – microbial drug and plant growth regulators. The experimental part of research was held during 2015–2017 in the field training and production department and research laboratory of the department of microbiology, biochemistry and plant physiology of Uman National University of Horticulture. Accounting and study of plants height and leaf-area duration in experiments were done in accordance with methodologies, described by Z. M. Hrytsayenko and co-authors. Statistical analysis of the results of the studies was carried out using the methods of dispersion analysis, described by B. A. Dospekhov. As a result of the research it was found: the height and area of the leaves of chickpea plants varied both by years and depending on the use of different norms of the herbicide Panda, entrenched separately and against the background of seeds processing PGR Stympo and MD Ryzobophyt. On the average over the years of observation over the independent action of MD Ryzobophyt (1,0 l/t) the plant height of chickpea with regard to control I grew into 2%, leaf-area duration with regard to control I grew into 12 %. At individual action PGR Stympo (0,025 l/t) with regard to control I grew into 16 %. In variants of cooperative usage of MD Ryzobophyt and PGR Stympo increasing of a chickpea height with regard to controls I contained 8 %, the index of leaf-area duration increased with regard to controls I into 20%. At individual usage of the herbicide Panda in limits 3,0 and 4,0 l/g the plant height grew into 1 and 8 %, the leaf-area duration of chickpea increased into 9 and 32% with regard to control I, at limits 5, and 6, l/g – in 4 and 2% the leaf-area duration of chickpea grew into 19 and 14% with regard to control I. While processing by a mixture of MD Ryzobophyt (1,0 l/t) and PGR Stympo (0,025 l/t) and entering the herbicide Panda in limits 3,0–4,0 l/g before the chickpea sowing the height of a crop surpassed the control I on 12 and 19 % , the leaf-area duration of chickpea increased into 39–83 % with regard to the control I, and at limits of entering 5,0 and 6,0 l/g – into 13 and 11 %. The duration increased into 69 – 33 % to control I. The highest indexes of plants height and leaf-area duration were recorded in the Panda herbicide application in limits of introduction 4,0 l/g against the processing of seeds before the sowing PGR Stympo (0,025 l/t) and MD Ryzobophyt (1,0 l/t) in particular, in this embodiment, the height of the plants increased by 19%, the leaf area - by 83%

The results of the research on economic and bioenergetic evaluation of different types of sainfoin growing depending on fertilizer, grass mowing height, seed inoculation and years of use were presented. Sainfoin is one of the most productive legumes with a high protein content, the green mass of which exceeds both cereals and some perennial legumes by the protein content. However, despite the significant advantages of sainfoin, the areas under this crop remain insignificant, especially in the Forest-Steppe zone. One of the reasons for this state is the undeveloped zonal technology of growing of different varieties of sainfoin with their economic and energy evaluation. Research methodology. Experimental studies were conducted during 2016–2018 at the research site of the SS of NULES of Ukraine “Agronomic Research Station” located in Pshenychne village of Vasylkiv district of Kyiv region. Scheme of the experiment: Factor A. Varieties of sainfoin (Common (Ametyst Donetsky variety); Transcaucasian (Adam variety); Hungarian (Smaragd variety). Factor B. Fertilizers, inoculation (without fertilizers and inoculation; N45Р60К90 + seeds inoculation with rhizotorphine; Р60К90 + seeds inoculation with rhizotorphine). Factor C. The height of grass mowing (5, 10, 15 cm). Method of sowing – by row, spring coverless. Rhizotorphine was used for inoculation. Conclusions. It was found that the highest conditionally net profit and the lowest prime cost of fodder unit and crude protein were obtained under common sainfoin growing, economic indicators of growing of Transcaucasian sainfoin and Hungarian sainfoin were much lower than the aforementioned. The highest energy efficiency coefficient and the lowest energy costs for growing of 1 ton of fodder units were obtained on the sowings of common sainfoin of Ametyst Donetsky variety.
