Подальше поширення сої  стримується недостатньо обґрунтованою зональною технологією її вирощування. Норма висіву впливала на величину врожайності сої більше, ніж спосіб сівби. Сорт Романтика максимальну врожайність мав за норми висіву 700 тис./га – 2,41 т/га. Занижені норми висіву сприяли зниженню врожайності насіння до 2,07 т/га за норми висіву 600 тис./га та до 1,82 т/га – за норми 500 тис./га. Збільшення норми висіву до 800 тис./га  було неефективним – 2,39 т/га. У скоростиглого сорту Устя найбільша врожайність була за норми висіву 700 тис./га – 2,48 т/га. Занижені норми висіву сприяли зниженню врожайності насіння до 2,11 т/га – за норми висіву 600 тис./га, до 1,99 т/га – за норми 500 тис./га. Збільшення норми висіву до 800 тис./га не сприяло підвищенню врожайності – 2,35 т/га. За зрідженого розміщення рослин характерне близьке до поверхні ґрунту закладання бобів, яке спричиняє значні втрати врожаю під час збирання.  In connection with the intensification of soybean production, there is a question arises of identifying the elements of cultivation technology, which should ensure its high productivity. Among them, the timing, methods and norms of sowing of different soybean varieties are decisive. Further spread of soya in conditions of unstable wetting of the Left-Bank part of Forest-Steppe is restrained by the lack of grounded zoning technology for its cultivation, especially in early sowing, where heat is a limiting factor and moisture is sufficient. The aim of the research was to determine the optimum soybean density by choosing the right seeding and seeding method to ensure optimal plant growth and development and high productivity. In determining the period of sowing, it was taken into account that the early term corresponds to the minimum soil temperature (8–10 ˚С), during which germination of soybean seeds is possible. The optimal time of sowing was determined when the soil was warmed to +12–14 ˚С. The late sowing period corresponded to an increase in the temperature of the soil to +16–18 ˚С. The results of the research showed that the level of soybean yields is largely determined by the change in the feeding area and the way in which they are placed in the crop. In this regard, the study of the influence of the size and shape of the feeding area on the competitive interconnections of plants in agrobiocenosis and the individual productivity of plants of soybean varieties is an important scientific problem. The sowing rate was greater than the sowing method, which affected the value of soybean yield. The sort Romantyka had a maximum yield of 700 thousand hectares per hectare – 2.41 tons/ha. The low seed rates contributed to a decrease in seed yield to 2.07 t/ha – under the seed rate of 600 thousand/ha and to 1.82 tons/ha – at the rate of 500 thousand/ha. The increase in the seed rate to 800 thousand/ha was ineffective – 2.39 tons/ha. In the fast-growing sort Ustia, the highest yield was 700 tones/ha – 2.48 tons/ha. The low seed rates contributed to a decrease in seed yield to 2,11 t/ha – under the seed rate of 600 thousand/ha, to 1.99 tons/ha – at the rate of 500 thousand/ha. Increasing the seed rate to 800 thousand/ha did not contribute to the increase in yield – 2,35 tons/ha. In congested crop, beans are formed in the upper part of plants, resulting in a low seed yield. The fluid distribution of plants is characteristic of the near-surface of the ground for laying beans, which causes significant harvest losses in harvesting.

Purpose. To determine the level of productivity of sunflower hybrids, their stability and plasticity for cultivation in the Left Bank Forest-Steppe of Ukraine.Methods. The field experiment was performed in the conditions of the Left-Bank Forest-Steppe of Ukraine in 2016–2018. The peculiarities of plant growth and development, formation of yield of hybrids ‘Ukrainskyi F1’ (k), ‘P64LL125’, ‘P63LE10’, ‘P64F50’, ‘P64F66’, ‘P63LL06’, ‘NK Konti’ (k), ‘NK Brio’, ‘P64LE99’, ‘Laskala’, ‘Kupava’. Yield plasticity was calculated and analyzed by the Ebergard – Russell method.Results. Over the years of research, the average yield of sunflower hybrids in the Left-Bank Forest-Steppe of Ukraine varied from 2.71 to 4.04 t/ha. The lowest yield was shown by the ‘Ukrainskyi F1’ hybrid – 2.42–3.05 t/ha, the highest ‘Laskala’ – 3.79–4.26 t/ha. It was determined that in the conditions of the Left-Bank Forest-Steppe, there is no absolute predominance of medium-ripe hybrids in terms of yield.Conclusions. According to the results of the analysis of yield plasticity of sunflower hybrids, it was determined that the group of samples with high yield plasticity includes ‘Ukrainskyi F1’, ‘P64F50’, ‘P64F66’, ‘NK Konti’, ‘NK Brio’, ‘P64LE99’, ‘Lascala’ and ‘Kupava’. They respond to the improvement of the level of agricultural technology and provide the maximum yield only under the conditions of optimal factors. Hybrids ‘P64LL125’, ‘P63LE10’ and ‘P63LL06’ are more stable in response to changes in growing conditions without reductions in yield. As for the shares of the influence of the studied factors, the yield of the hybrid ‘Ukrainskyi F1’ was most influenced by the conditions of the year, ‘NK Brio’ – the sowing rate. For the ‘NK Ferti’ hybrid, the conditions of the year and the sowing rate are equally important.

Floristic Structure

The article presents the results of study of floristic structure and productivity of the dry meadows preserved in the ravine and gully system in the Zmiiv District of the Kharkiv Region. The research was carried out at the model sites with floral composition and features of use typical for the Left-Bank Forest-Steppe of Ukraine. It was established that the total phytocenosis productivity depends on the phytomass fluctuations of two main groups of plants, forbs and grasses. The flora of the studied meadows includes at least 87 vascular plant species. The ten main families altogether number 70 species (80.5 % of the species composition). The families Asteraceae Bercht. & J. Presl (23 species, 26.4 %), Fabaceae Lindl. (11 species, 12.6 %) and Poaceae Barnhart (8 species, 9.2 %) are presented best. This ratio of families is characteristic of herbaceous phytocenoses of the Holarctic floristic realm. The Poaceae family plays the leading role in the formation of meadow phytocenoses, since its members often dominate the main meadow formations. Analysis of the flora ecomorph spectrum revealed prevalence of a xerophilous group that includes meadow, meadow-steppe and steppe species. The obtained data indicate a rather significant xerophytization of the study area, which is typical for the growing conditions of the dry meadows located on the watersheds with atmospheric type of humidification only. Perennial herbaceous meadow-steppe and some ruderal species prevailed in the life form spectrum (77.0 %), which is characteristic of the meadow flora of the Kharkiv Region. Annual segetal weeds, introduced from neighboring fields, contribute significantly to the meadow flora (17.2 %), in particular, such adventive species as Ambrosia artemisifolia L., Amaranthus retroflexus L., and Cyclachaen axanthifolia (Nutt.) Fresen. The research of phytocenose productivity showed that the Poaceae proportion in the meadows with high productivity is usually about 35‒40 %. In the meadows with low productivity, it can exceed 50 % that is explained by the leading role of the family Poaceae in the formation of meadow phytocenoses under high xerophytization of the vegetation cover.

The Way

The contemporary condition of soil cover in Ukraine is characterized. The attention is focused onto widespread degradation processes in soils. The causes that determine the development of these negative processes are considered. The contemporary informational support for the condition of soil cover in Ukraine is estimated. In general, the current available information is of narrow-departmental nature, obtained by different methods and non-correlated monitoring programs. As a rule, it is stored in under-structured databases, incompatible with other information systems; mainly recorded on paper media unusable with modern technologies, whereby such information resources are diffi cult to be compiled together. These disadvantages are strong constraints against consistent usage of materials for evaluation, forecast and management of changes in the soil cover. The Soil Observation program should thereby be combined with Agrochemical Passportization and ecology-ameliora- tive monitoring; in other words, the application of innovative soil-agrochemical methodology is considered. Each individual type of surveys shall complement the others, and taken altogether, they shall constitute a con- sistent Information System, capable of solving the problems of assessing the condition, forecasting, manage- ment, usage and protection of soil resources. The monitoring procedures should be conducted on the basis of a new soil concept in line with unifi ed programs and methods, so as to meet European approaches to the maxi- mum extent. Such a technical composition enables getting information on present-day processes in soils, and is the only combination that actually helps us to “ecologize” our knowledge of soils, which is the leading trend in the scope of global soil-science. Thus obtained results will serve as a State-owned tool which would subse- quently facilitate the use and protection of soil resources all over the country, to be involved in a united global soil-information scope. The attention is focused onto social signifi cance of the information on soils and their fertility in terms of land resources optimization, as well as the formation of sustainable land use in Ukraine. Aim. To demonstrate the long-term effect of different ways of tillage of typical low-humus chernozem on the change in humus content and composition and the direction of transformation processes of organic fertili- zers. To study the changes in the structure of energy reserves in group and fractional composition of humus in typical low-humus light-loamy chernozem of the Forest-Steppe of Ukraine. Methods. Field, laboratory, microbiological, computational, mathematical and statistical. Results. It was determined that in conditions of long-term subsurface tillage the most effi cient humus accumulation occurs in the 0–20 cm layer of chernozem with simultaneous increase in its content in the lower part of the processed layer without any accumulation differentiation. Surface tillage leads to expressed differentiation in humus accumulation in the 0–20 cm layer of soil (0.005 % per year). When 6 t/ha of humus are replaced by 7 t/ha of by-products the intensity of humus accumulation is decreasing regardless of the way of tillage, but humus accumulation was found to be the most effi cient for subsurface tillage. The application of subsurface tillage leads to the increase in the ratio of C HA : C FA , which is conditioned by the increase in the humifi cation of plant remains of by-products in the 0−20 cm layer of soil by 110–112 % – for subsurface tillage, and by 105 % – for surface tillage. Conclusions. It was established that systematic subsurface tillage of typical chernozem of the Left-Bank Forest-Steppe of Ukraine leads to the structuring both of the total reserves of energy С org , and its quality content, aimed at the increase in the intensity of the processes of humifi cation and accumulation of organic carbon, and the decrease in miner- alization. The ratio of energy reserves С org of humic acids to fulvic acids in the 0−30 cm layer of chernozem is 1.85−1.87 regardless of the way of tillage, which testifi es to the repeatability of humus accumulation, but the total reserves of energy С org was higher for subsurface tillage (+ 31 Teracalorie/ha) compared to deep plough- ing. As for the surface tillage, the energy enrichment was at the level of deep ploughing.

SUMMARYField trials are described in which the seed yield response of row-sown sesame to increasing plant population was examined, and in which row-sowing was compared with broadcasting at different seed rates. Maximum yields were obtained at an intended 200 to 250 × 103 plants ha−1 but yields were not greatly affected by a wider range of populations. Broadcasting, the normal local practice, gave yields slightly higher than those from rows 50 cm apart, the un-thinned rate of 800 × 103 viable seeds sown ha−1 yielded as well as treatments thinned to the optimum population, and double this seed rate, unthinned, gave the lowest yields, especially in rows.

The anthropological composition of the population buried at the cemetery of the Scythian Age near Svitlovodsk city (Kirovograd region) is analyzed in the paper. The burial ground is located on the border of the Forest-Steppe and Steppe Zones of the Right Bank of the Dnieper. The anthropological material under study comes from cemetery without mounds. Archaeologists date the main massif of burials to the 4th century BC. The anthropological composition of the population that was buried at this burial ground was not homogenous. The male series of skulls is characterized by a long, medium-wide, high, dolichocranic skull. The face is of medium size, it is mesognathic. The horizontal profile of the face at the upper level is medium, but with a tendency to the sharp; at the middle level, the face is strongly profiled. The orbital and nasal indexes are medium. The bones of the nose are moderately protruding. The average characteristics of the male population fit into the range of variations of the Scythian series. The male series belongs morphologically and statistically to the circle of the steppe Scythian groups. The male group from the burial ground near the city of Svitlovodsk is close to the series from the Nikolaevka burial ground on the Dnister River, the group of skulls from the burial mounds near the village of Shirokoe (Left Bank of the Dnieper River), the group of skulls from the burial mounds near the village of Vyshchetarassivka, a series of skulls from the Mykhailivka burial ground. Of the forest-steppe series, only the combined group of skulls from the Trypillya region is somewhat close to it. All these statistically and morphologically similar groups originate from different territories. This illustrates the specifics of the settlement and demonstrates the mobility of the Scythian groups. The female series from the burial ground is characterized by a long, narrow, medium-high skull, mesocranic in shape. The size of the face is small, it is mesognathic. The horizontal profile of the face at the upper level is moderate, at the zygomaxilar level it belongs to the category of sharp, but with a tendency to moderate. The orbital index is medium, the nasal index belongs to the large category. The bones of the nose are medium protruding. The female series from Svitlovodsk burial ground turns out to be the most gracile among the Scythian series in Ukraine. For this reason, it differs significantly from the entire massif of the steppe Scythian series. The closest to the Svitlovodsk series is a group from mounds near Nikopol.

The experimental studies were carried out on the fields of the Sumy NAU Training Research and Production Complex (TRPC) during 2016–2018.The soil of the experimental plot is typical deep-medium humus, large-dusty and medium-loam black soil on forest trees. The subject of the research was a white mustard variety of Oslava created at the Institute of Feed and Agriculture of the Podillya NAASU, entered in the Register of varieties suitable for cultivation in Ukraine in 2010. The aim of the research is to optimize the nutrition of the white mustard variety of Oslava through the complex application of mineral fertilizers and foliar fertilization under the conditions of the northeastern forest-steppe of Ukraine. The analysis of weather conditions, in particular the hydrothermal coefficient of Selyaninov (HTC), established that 2016 season was wet (HTC = 1.60), 2017 and 2018 were dry (HTC = 0.59 and 0.46). During the research, the cultivation technology was generally accepted in the experimental area, except for the elements studied. The results of the three-year study on the influence of foliar fertilizing under different mineral nutrition backgrounds on the yield of the white mustard variety Oslava are presented. It was found that the application of mineral fertilizers and complex fertilizers for the foliar feeding had a positive effect on the morphometric parameters of the white mustard, in particular, increased the plant height and the number of branches of the first order. The use of mineral fertilizers at the rate of N30P30K30 provided an increase in the yield by 0.34 t/ha, N60P60K60 – by 0.55 t/ha, N90P90K90 – by 0.61 t/ha on an average compared to the control. Therefore, for the maximum yield (2.14–2.21 t/ha) with a mass of 1000 seeds (5.39–5.54 g) of the white mustard under the conditions of the Northeastern Forest-Steppe of Ukraine, foliar fertilizing of Vuxal boron (3.0 l/ha) + Vuxal bioaminoplant 3.0 l/ha) and Spectrum B + Mo (2.0 l/ha) + Spectrum Ascorist (3.0 l/ha) should be applied on the background of N60-90P60-90K60-90, what provided an increase in the yield compared to the control of 0.58-0.65 t/ha.
