Phenological Phases

Studies were conducted to study the effect of air temperature and the amount of precipitation on the growth and development of spring wheat plants. Analysis and quantitative description of the dependence of the duration of interphase periods was carried out by methods of correlation and regression analysis, changes in the duration of periods by calculating the coefficient of variation. For analysis, we used the results of long-term field observations (2014–2019) over the time of the onset of phenological phases in spring wheat varieties of the mid-ripe group in the Ural steppe, as well as published data of Davlekanovskiy GSU of the Republic of Bashkortostan for 1993–2016. An increase in temperature during all periods of vegetation accelerates the growth and development of plants, an increase in rainfall, on the contrary, slows down these processes. The change in hydrothermal conditions most strongly affects the duration of tillering – heading and heading – waxy ripeness periods. The coefficient of variation of their duration is 26.9 and 28.7, respectively. With an increase in air temperature by 1°C in the range of 11.3 ... 20.50С, the tillering-heading interfacial period decreases by 0.408 days, and the ripening of spring wheat grain (at a temperature of 10.7 ... 24.2°C) is accelerated by 0.424 of the day. An increase in precipitation by 10 mm in the range of 1.0 ... 126.2 mm slows the onset of heading by 0.39 days, waxy ripeness of grain (with a total of 0 ... 131.1 mm) - by 0.40 days. Statistical models of the dependence of the duration of interphase periods of growth and development of spring wheat plants on the amount of precipitation and average daily temperature can be used to predict the calendar dates of the onset of phenological phases and the operational adjustment of technological operations to care for sowing

When sowing millet seeds in the third decade of May in the Kama area of the Republic of Tatarstan, it was established a connection between cores destruction by melanosis with a prolonged period of millet plant growth. The variation of planting dates showed, that the hydrothermal conditions of interphase period, beginning buttonhole + 20 days, influenced on the degree of nuclei damage by melanosis of different maturity groups. Form weevil is one of the factors of protection against melanosis.

Tourism in Croatia primarily relies on the “sun and sea” product as the main asset of its offering. The current lack of adequate infrastructure, an underdeveloped winter tourism offering and the lack of stakeholders’ interest in developing winter tourism products are only some of the problems facing winter tourism development in Croatia. Winter tourism development does not include only snow-related activities but all outdoor activities, where weather and climate play a significant role. This paper analyzes the relationship between average monthly climate indicators in summer and winter periods and the number of overnight stays in Croatia from 1977 to 2014. In the regression analysis, we used a multivariate model with first difference specification and ordinary least square (OLS) estimation, in which past period of the dependent variable was also included. Seasonality was controlled by using quarterly dummy variable. The analyses for coastal and continental Croatia were made separately. Using regression and correlation analyses, we prove that Croatian tourism in the coastal part is strongly related to climate parameters while that influence in the continental part is less significant. The main hypothesis of the paper is that, with the increase in temperature, the tourism season will be prolonged in both the coastal and continental part of the Republic of Croatia. However, other interventions in tourism (such as raising the quality, expanding the offering etc.) can also increase tourism results since climate parameters do not have the same effect on the continental and coastal part of the Republic of Croatia. The impending climate change will cause climate indicators to change, thus unlocking the potential for winter tourism development in areas not related to the sea, but also requiring the development of various forms of special-interest tourism. Winter tourism in Croatia represents a big potential not only because climate change will potentially make winters in Croatia milder but also because, with the right policies, there is a huge potential to develop the undeveloped region of continental Croatia with products that would diversify the Croatian tourism offerings.

Optimization of planting dates and plant density for maize cultivation for green fodder is of particular importance under increased aridity in the Republic of Crimea. The aim of the research was to identify optimum planting dates and plant density for maize hybrids for green fodder harvested at the late milk stage under rain-fed conditions of the steppe zone of the Crimea. In the course of the experiment, we found that for the period from 2016 to 2019 yield of green fodder depended on the hydrothermal conditions of the year and plant density, as well as we observed the interaction of planting dates and conditions of the year. The optimum plant density was 70 thousand plants per hectare. On average, the yield of green fodder of early-ripening maize hybrid ‘Nur’ was 19.58 t/ha; medium early hybrid ‘Mashuk 220 MV’ – 19.25 t/ha, medium ripening hybrid ‘Mashuk 355 MV’ – 21.3 t/ha.

Forest Shelter Belts

Forest shelter belts are one of the effective approaches in the fight against wind erosion, improving the microclimate of fields, protecting roads and reservoirs. The problem of assessing forest plantations and prospects for their creation is relevant for many countries of the world, due to the problem of desertification, water and wind erosion, as well as the global food crisis. The carried out analysis of scientific literature has shown that the existing assessments of forest shelter belts with insufficient degree are being taken into account the modern methods of remote sensing.Therefore, the problem of assessing forest shelterbelts from satellite imagery is relevant.The main part and research results. During the summer period of 2019, in the territory of the protective forest plantations of Fergana Valley of the Republic of Uzbekistan there were laid 170 testing plots. Then 20 test sites, which were used as reference for thematic mapping, there were laid with the collection of additional information: location coordinates and bookmark location.The purpose of the study is to assess the area of forest shelter belts zones of the Republic of Uzbekistan using remote sensing.The object of the study is forest shelter belts of Fergana Valley of the Republic of Uzbekistan.

Carapace mites are important regulators of the mineralization of organic residues and the immobilization of various biogens in the soil. In the course of the research conducted on the territory of the Gunib district of the Republic of Dagestan, only 89 species of shell mites belonging to 61 genera and 41 families were identified. New data have been obtained that complement the list of species of shell mites in the Caucasus as a whole. Recently described Liacarus (Dorycranosus) musaevi, and two endemics of the Caucasus – Xenillus sculptrus and Suctobelba cornigera – were noted for region. Among other groups of soil microfauna, shell mites occupy a leading position, both in terms of their number and abundance of species. In studies conducted in mountain systems, it was found that the General pattern is a decrease in the number of microarthropods with an increase in absolute height. Very often, the pattern of changes in the taxonomic richness and population density of the microarthropod complex is diamond-shaped, characterized by maxima in the zone with the most favorable microclimate for a large group of species. From top to bottom, the microarthropod population density and taxonomic richness decrease along the mountain profile. As a result of the study, the maximum population density and abundance of oribatid species is observed in the soil of a birch forest and its gradual decrease as it transitions to grasslands, which is explained by changes in the hydrothermal conditions of soil horizons, both due to an increase in height and due to a change in the nature of vegetation to treeless.

The technology of cropping should vary depending on the climatic conditions of a particular region. In developing resource-saving technologies of spring wheat cultivation, we must remember that during the growing season in the Republic of Tatarstan every square centimeter of the soil surface gets a day 1 kcal of heat, the sum of positive temperatures above 10 C in the republic is 2100-2200º, annual rainfall is 450-460 mm of precipitation; an average yield of 2.5 tons of grain per 1 hectare per ton 180 mm of moisture is consumed. This misallocation of productive moisture mainly occurs due to violations of cultivation technology (soil preparation, planting dates, insufficient use of macro-and micronutrients, care for crops etc.). In this regard, during the spring wheat cultivation it is necessary to achieve a minimum of productive moisture evaporation from the soil, the source of precipitation , which would get pretty high yields even in the driest years .

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
