It has been determined the ecological condition in Ukraine and the world has been by the manifestations of degradation processes in terrestrial ecosystems and small river basins on the principle of causation. It has been suggested the conceptual bases of restoration of channels of small rivers and their basins by carrying out engineering, culture-technical works in channels and floodplains of small rivers, the organization of adaptive landscaping of the territory, and also carrying out agro-, chemo-, bio- and phyto-meliorations in their basins without disturbance the basis of erosion and giving impetus to self-renewal of natural fauna and flora. In the processes of nature restoration, the leading role of domestic science in the methodological and methodological support of projects has been identified, and importance is attached to the restoration of natural biodiversity and biologization in agricultural systems. We proposed to create a state mortgage land bank with a concentration in it of land fees of ecological funds with the involvement of domestic and foreign investment. It is recommended to test the idea in several model pools of soil-climatic zones with further replication in Ukraine and the spread of technology beyond its borders. Conclusions. А systematic approach is needed to carry out reclamation works in the basins of small rivers is to implement the basin approach. To implement the program, the Verkhovna Rada of Ukraine must adopt the Law of Ukraine “On Agriculture, Sustainable Development of the Biosphere and Ecological Nature Management”, the project of which was developed at the NSC “Institute of Agriculture of NAAS”.

To determine the peculiarities of formation of productivity, as well as the chemical composition, nutritional value and energy intensity of grass forage, depending on the measures of surface improvement of the meadows of the Carpathian mountain forest zone. Methods. Field works, laboratory, mathematical-statistical. Results. Productivity of haymaking and perennial mowing fluctuated on the range of 2.15–4.77 t/ha and 1.95–4.11 t/ha during the 3-year research of dry mass yield. Compared to the variants without additional sowing of grasses and fertilizer use, the highest productivity of haymaking was upon the additional sowing of cereal grass mixtures and applying of N60P30K60 – 12 % and 85 %, respectively. Productivity of perennial mowing increased upon the additional sowing of Trifolium repens and applying of P30K60 on 85 % and 111 % respectively. The best uniformity of distribution of biomass crop by slopes was obtained by the use of multifaceted use of creeping clover with the introduction of P30K60, when the proportion of 1st slope was 39%, 2nd - 33 and 3rd – 28% with unevenness, which is expressed by the coefficient variation - 18%.

Studies aimed at identifying the relationship between important economic characteristics of wheat and heights are relevant given the long process of wheat domestication. The article highlights the results of a research of plant height and lodging resistance of 28 winter wheat varieties created in the period from 1971 to 2017. Studies have shown that varieties vary in height and lodging resistance over the years. In terms of height relative to the variety-standard Perlyna Lisostepu, the highest yield were of the varieties Zhuravka (112 cm), Miryutinka (113 cm), Kievskaya-73 (102 cm), Pamiati Girka (103 cm). The lowest varieties were Gnome (65 cm), Analog (77 cm), Kievskaya polukarlikova (76 cm), Shchedraya Polesia (83 cm). According to the resistance to lodging, the studied varieties can be attributed to different groups. Varieties created after 1992 were resistant to lodging: Kraevid, Polesskaya-90, Gnom, Analog, Kesaria Polisska, Olzhana. Conventionally dividing varieties into groups according to the years of creation in the period from 1971 to 2012, you can notice a tendency to decrease in height and increase resistance to lodging with each subsequent variety change. According to the results of field tests, the average height of winter soft wheat varieties of the Institute of Agriculture created in the period from 1992-2017 decreased by 5 cm compared to varieties created in the period from 1971 to 1992.So, the results obtained indicate the active involvement of short-stemmed genotypes in the breeding process of winter wheat, which are still being successfully studied. Most varieties of the Institute belong to the semi-dwarf group in terms of height and are highly resistant to lodging, and therefore are promising as a source of economically valuable traits.","PeriodicalId":268656,"journal":{"name":"Agriculture and plant sciences: theory and practice","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116043049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To determine and evaluate the indicators of changes in the water regime of the most common varieties of potatoes (on the 60th and 85th day of germination) in the conditions of central Polissya of Ukraine, namely the coefficients of water recovery, water retention, drought resistance and water deficit. Methods. Field and laboratory-based, selection and statistical. Results. The coefficients of water retention, water recovery capacity and drought resistance and water deficit of plant leaves are determined. The highest water content of potato leaves was observed among the following varieties: Tyras, Nahoroda, Serpanok, Slovianka and Chervona Ruta. It is established that the mechanism of water recovery in potato varieties of different maturity groups is different, the highest percentage of this indicator in early-maturing varieties is observed on the 60th day from germination, in the mid ripening group on the 85th day from germination. High value of the integrated indicator of water recovery was demonstrated by the following varieties: Tyras, Vyhoda, Yavir, Lietana, Slovianka Volodarka, Bazaliia and Chervona Ruta. It was found that on the 60th day from germination among the following potato varieties: Chervona Ruta, Serpanok, Avanhard, Mezhyrichka, Nahoroda, Oleksandryt, Radomysl and Bazaliia, the drought resistance coefficient was ≤ 80%. It was found that only in the varieties Tyras and Slovianka, on the 85th day after germination, there is an increase in the numerical expression of the drought resistance coefficient, which indicates an increased degree of adaptation of plants to soil moisture deficiency. In the first and second record the indicator of water deficit of the most of the studied varieties of potatoes was within acceptable limits, indicating a slight negative effect of weather conditions on the physiological state of plants. A slightly increased indicator of water deficit was observed on the 60th day of germination among the following potato varieties: Tyras, Volodarka and Levada, but within two weeks it decreased to a safe level.
