Current situation and agricultural management on the non-black earth area of Russia arebeing gradually worsen by the negative natural factors such as a significant increase of weather based climatic abnormal risks, deterioration of agro-meliorative conditions of agricultural lands because of colonization by tree and shrubbery vegetation and secondary bog formation, hidden degradation of soil fertility. When combined with functional loss of ameliorative complex and meliorative systems amortization, regional agriculture adaptation possibilities were rapidly limited. Production shortfall due no abnormal weather conditions for particular field crops was 19…48% during last five years, level of business realization of bioclimatic potential on a field was decreased by 7…12%.The complete realization of regional agricultural adaptive potential to weather based climatic changes and limitation of greenhouse gases emissions is possible on a basis of regeneration ofalll functions and aspects of ameliorative complex management. Toward this goal the coordinated actions of federal and regional management of Agricultural Complex, Scientific and Educational institutions, project foundations and managers are needed in a relation to human resources, scientific and regulatory supply. Any incomplete treatment in these fields inherent in visual negative consequences for food security and social economic development of rural areas of non-black earth zones not only at the current historical moment, but in a future also. Fundamental influence of solving of these problems deserves to scientific supply of innovative ameliorative complex, renewal of which should be based on principals of resources and energy preservation, nature management, computerization and digitalization management. During a long term research it was established that increase of average vegetation period temperature by lоСhas increased productivity of winter wheat, barley and summer wheat in average on 0,7 tons per ha, winter wheat and oat on 0,4 tons per ha, potatoes – 8,2 tons per ha, edible roots-6,4 tons per ha, cabbage 9,8 tons per ha, dry basis of herbage of multi and one age grasses–0,5 and 0,7 tons per ha. Increase of СО2 Concentration from 0,35 to 0,45% during last twenty years contributed into grow of yield in regional agriculture which can be estimated as 0,3 tons per ha per measure; searching remedy for agroclimatical risks decreasing production became drainage and irrigation systems (decrease 3…5 times);new method of reclamation of abandoned areas with transformation of biomass of tree and shrubbery vegetation into biochar makes it possible to decrease СО2 emissions up to times and get an adverse balance of СО2;secondary reclamation of lands covered by trees and shrubbery on area of 22ha used for vegetables and area of 37ha used for forage crops could supply a farmer with work and revenue sufficient for maintenance of one child what is on the major facts of population declaim in rural areas.

The effect of reduced and conventional tillage on soil compaction, soil moisture status and carbon-dioxide emission of the soil was studied on a meadow chernozem soil with high clay content in the soil cultivation experiment started in 1997 at Karcag Research Institute. Our investigations were done on stubbles after the harvest of winter wheat and winter peas after the very droughty vegetation period of 2014/2015. We established that the soil in both tillage systems was dry and compacted and the CO2-emission was very low. The positive effects of reduced tillage could be figured out only in the soil layer of 40–60 cm in the given weather conditions of that period.

The current paper has presented the trial results of the winter wheat varieties developed by the ARC “Donskoy” in 2018 -2020. Currently, the farmers have bred a lot of different wheat varieties, but they are not able to take into account all the peculiarities of their cultivation. The purpose of the current work was to study the features of the autumn and spring-summer vegetation periods of the winter wheat varieties developed by the ARC “Donskoy” in the area of dark chestnut soils of the Volgograd region. There have been selected 10 winter wheat varieties for the trials. The field trial was laid down on dark chestnut soils of the lands of the Serafimovichsky district in the Volgograd region. The study was carried out according to the generally accepted B.A. Dospekhov’s methodology. The field trials showed that the germination of winter wheat was influenced by a seeding depth, which was 7-9 cm. The best germination was found among the varieties ‘Asket’, ‘Etyud’, ‘Lilit’, ‘Donskaya Step’ and ‘Zhavoronok’. During the trials, the formation of a productive stand was greatly influenced by the weather (the length of a spring tillering period, precipitation in May), as well as the traits of the variety. The winter wheat varieties ‘Etyud’, ‘Shef’, ‘Donskaya Step’, ‘Krasa Dona’ were able to form a large number of productive stems under favorable weather conditions. Under insufficient moisture supply, the largest number of productive stems was formed by the varieties ‘Lidiya’ and ‘Lilit’. The highest tillering intensity during an autumn vegetation period was shown by the variety ‘Lidiya’ (4.7–6.2 shoots), including the varieties ‘Zhavoronok’ (4.2–5.4 shoots) and ‘Etyud’ (4.0–5.3 shoots). The largest productivity was produced by the varieties ‘Donskaya Step’ (4.97 t/ha), ‘Zhavoronok’ (4.95 t/ha), ‘Krasa Dona’ (4.90 t/ha) over three years.

The analysis of the Crimean weather conditions during the autumn vegetation period of winter wheat indicates climate warming and, in this regard, the necessity to adjust the optimal sowing dates. The purpose of the current study was to estimate the productivity and grain quality of winter bread wheat varieties depending on different sowing dates. The objects of the study were five winter wheat varieties sown in 5 dates from October 1 to November 30 with an interval of 15 days. Field trials were conducted with appropriate observations, records, measurements and analyzes, according to the methodology of the State Variety Testing. Statistical processing of the trials was carried out by the B.A. Dospekhov’s method of dispersion and correlation analyzes. The study was carried out through three years, two vegetation periods of which (2017–2018 and 2019–2020) were dry, one period (2018-2019) was favorable for the development of winter grain crops. According to the results of the analysis of variance, there have been identified significant differences in the effect of all three factors (‘variety’, ‘length’ and ‘year’) and their correlation in all combinations on the productivity formation. The factors ‘sowing date’ (33%) and ‘correlation between date and year’ (49%) had the greatest influence on the productivity formation. In 2018, the most optimal for all studied varieties was the second sowing date (15.10), in 2019 it was the first (1.10), and under the conditions of 2020, the later sowing dates were more favorable, and the 4th period was marked as optimal (15.11). The mean productivity of all varieties at the optimum sowing dates was 4.0; 5.5 and 3.46 t/ha, respectively. The factors ‘sowing date’, ‘year’, and the correlation between them significantly influenced protein percentage in grain. Their effect on the manifestation of the above trait was 29%, 14% and 23%, respectively; on gluten content it was 29%, 16% and 21%, respectively.

The values of the natural environment in the subject literature are commonly indicated as an asset conducive to development shaping the competitiveness of areas with such values. The paper attempts to assess the use of endogenous potential of such areas in shaping the multifunctional, sustainable development of rural areas that have such qualities. In particular, the aim was to check to what extent the sme sector, dominating in the economic structure of rural areas, solves the key problem of labour market imbalance and population migration in environmentally valuable areas. The area of detailed research is Podkarpacie, the Polish region considered as a peripheral, border region, the least urbanized region with the highest share of areas covered by various forms of nature protection and forestation, with one of the lowest gdp per capita indicator in the country. For the purpose of implementing the research assumptions, a taxonomic unit (using the complete linkage method) consisting of powiats with the highest concentration of features characteristic for rural areas of high natural values was separated. Synthetic indicators calculated on the basis of the Hellwig taxonomic development pattern method and a positional method using Weber's median were used to assess the diversity of entrepreneurship level. The research confirmed that the non-agricultural economic activity sector is less developed in areas of high natural value. Despite positive developments in the enterprise sector, their potential is too weak an economic base for addressing unsustainable labour market problems, as evidenced by high unemployment and a high negative migration balance. This limits the use of the endogenous potential of these areas and is not conducive to the concept of multifunctional, sustainable development. Migration poses a threat to the depopulation of these areas with all the negative consequences associated with such processes. This is a challenge for the studied areas and regional policy.

Data of long-term researches (2015–2018) in southern forest-steppe zone of the Republic of Bashkortostan, is justified theoretically and experimentally the mode of irrigation of potatoes on leached chernozems of unsatisfactory, satisfactory and good ameliorative condition of irrigated lands. For the growing periods of potatoes with different heat and moisture supply, the number of watering, the timing of their implementation, irrigation and irrigation norms are established. On lands with unsatisfactory meliorative state the number of irrigation depending on weather conditions of potato vegetation period varied from 0 to 3 (1.5 on average) with average irrigation norm – 990 m3/ha. With satisfactory meliorative state of lands the number of irrigation on average increased from 0 to 4 (2.3 on average) with irrigation norm – 1305 m3/ha. On lands with good meliorative state the number of irrigation was the highest – from 1 to 5 (3 on average) with average irrigation irrigation norm is 1653 m3/ha. It was noted that in the dry periods of potato vegetation the greatest number of watering was carried out (3–5 watering), and in the wet periods (2017) watering was not carried out except for the area with a good reclamation state, where only one irrigation was carried out by the norm of 550 m3/ha. Water consumption of potato was studied in dynamics as a whole during the growing season and the months of the growing season depending on weather conditions of vegetation period and land reclamation condition of irrigated lands, as well as in the control (without irrigation). The lowest total water consumption was in the area without irrigation and averaged 226.8 mm. In irrigated areas, its values increased to 319-353.4 mm. The average daily water consumption varied from 2.12 to 3.3 mm. The highest rates of potato water consumption were observed in June and July, and the lowest – in May and August. In the total water consumption of potatoes on the site without irrigation, the largest share was occupied by atmospheric precipitation and in addition to them the arrival of moisture from the soil. Irrigation water was used in irrigated areas along with precipitation, the share of which was 30.2–46.1 %.

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.

In agriculture, the components of production cycles are likely (stochastic) in nature. This is especially true for harvesting. The duration of this period depends on the weather conditions, the biology of plant development, the variety of culture, the composition of the soil, agro technical techniques, etc. In connection with this, there is a need for scientific and production searches for such forms of organization of the harvesting process that would allow harvesting in short agronomic terms and substantially reduce due to this loss. The purpose of the research is to substantiate the structure and composition of the technology of harvesting and transport complexes for different technologies of harvesting cereal crops by operational and energy indicators to reduce the material and energy costs of harvesting. To calculate the comparative estimation of energy costs of complex fuel and operating costs for different harvesting technologies of winter wheat, four technologies are considered: traditional technology - direct harvesting without straw shredding; traditional technology - separate harvesting; zero technology - the use of harvesting equipment of domestic production; Zero technology - the use of harvesting techniques imported production. For these technologies, according to the methodology of the latest scientific research, technological maps for the harvesting of winter wheat have been developed. A comparative analysis of operational and energy costs of harvesting winter wheat indicated that the least cost is zero technology using domestic production technology, and the most expensive is conventional technology with direct combine harvesting. The presented results of researches of various technologies of grain cereal harvesting according to the structure and composition of equipment of harvesting and transportation complexes indicated that reduction of operational and energy expenses is possible due to increase of productivity, reduction of book value and quantity of harvesting equipment in the composition of harvesting - transport complexes at performance of works in optimal agro technical terms with minimal crop losses.

The climate changes and increased drought frequency still more frequent in recent periods bring challenges to management with wheat straw remaining in the field after harvest and to its decomposition. The field experiment carried out in 2017–2019 in the Czech Republic aimed to evaluate winter wheat straw decomposition under different organic and mineral nitrogen fertilizing (urea, pig slurry and digestate with and without inhibitors of nitrification (IN)). Treatment Straw 1 with fertilizers was incorporated in soil each year the first day of experiment. The Straw 2 was placed on soil surface at the same day as Straw 1 and incorporated together with fertilizers after 3 weeks. The Straw 1 decomposition in N treatments varied between 25.8–40.1% and in controls between 21.5–33.1% in 2017–2019. The Straw 2 decomposition varied between 26.3–51.3% in N treatments and in controls between 22.4–40.6%. Higher straw decomposition in 2019 was related to more rainy weather. The drought observed mainly in 2018 led to the decrease of straw decomposition and to the highest contents of residual mineral nitrogen in soils. The limited efficiency of N fertilisers on straw decomposition under drought showed a necessity of revision of current strategy of N treatments and reduction of N doses adequately according the actual weather conditions.
