The results of studies of the chemical composition of atmospheric air showed that the concentration of ammonia (0.2520 mg/m3), nitrogen dioxide (0.3942 mg/m3) and hydrogen sulfide (0.0269 mg/m3) exceeded the MPC requirements. The seasonal dynamics of the spread of aerogenic pollutants revealed a decrease in NO, NO2, H2S, SO2 from winter to the spring-summer season. However, the content of such pollutants as NH3, CO and dust increased significantly in summer to 0.0816, 3.7140 and 0.0289 mg/m3 respectively. During bio-indication of 363 trees only 4 species of the 16 studied ones were characterized as healthy (K<1.5). The overall level of attenuation was 2.16 (“weakened forest”). Evaluation of the fluctuating asymmetry showed high resistance of the maple (Acer Platanoides) to environmental pollution (the level of asymmetry in the transport zone was 0.039 against 0.077–0.078 in the silver birch (Betula pendula) and the fragrant poplar (Populus suaveolens). The high level of anthropogenic pollution in the transport zones of the city adversely affected roadside biotopes. It has been proven that roadside phytocenosis is significantly sparse and the population density drops sharply by 50–100 %, compared to cleaner functional areas. The results of lichenoid indication showed that in most of the sites studied, the air was highly polluted (pollution class 1) and the concentration of SO2 was 0.10–0.30 mg/m3.

In the conditions of the south of the Nonchernozem Zone, intraspecific hybridization of winter soft wheat was carried out. When selecting parental forms used in crossing, special attention was paid to such economically valuable traits as productive tilling capacity, the number of grains and the mass of grain per spike. The true (Htru) and hypothetical heterosis (Hhyp) on the basis of “plant height”, “length of the lower internode”, “length of the upper internode”, “general tilling capacity”, “productive tilling capacity”, “spike length”, “number of spikelets”, “number of grains” and “grain weight per spike” were determined. It was established that the inheritance of quantitative traits in hybrids of the first generation was distinguished by the complex nature of distribution by types. Studies have made possible to identify 5 hybrid combinations F1, in which the effect of heterosis manifests itself simultaneously on five quantitative characteristics (ear length, number of spikelets per ear, number of grains per ear, grain weight per ear, mass grain from a plant).

В статье рассмотрены вопросы использования современных жидких удобрений в условиях Нечерноземной зоны России. В последнее время интересы потребителей возросли, агропромышленные предприятия ежегодно вносят дополнения в технологию выращивания масличных культур и их переработки. Получили распространение такие перспективные масличные культуры как горчица белая, соя, лен масличный, рапс, сурепица яровая, рыжик яровой и другие. В 2018 году посевная площадь, занимаемая масличными культурами, составляла 121,1 тыс.га ( 25,7 тыс.га к 2017 году). Из них максимально 50,2 тыс.га отводится рапсу и 42,2 тыс.га подсолнечнику. В 2019 году масличными культурами в Рязанской области было занято более 150 тыс.га. Целью исследований явилось изучение действия листовых подкормок многокомпонентными жидкими удобрениями в двух фазах вегетации в посевах горчицы белой. В условиях полевых опытов проведены исследования особенностей роста и развития горчицы белой при использовании комплекса удобрений. В исследованиях растения получали необходимое количество влаги и тепла, а комплексное жидкое микроудобрение обеспечило более интенсивный рост растений, увеличило показатели фотосинтеза. Максимальное количество семян было получено у сорта Люция, на варианте Азотовит1 л/га Фосфатовит 1 л/га РауАктив 1 л/га 21,2 ц/га. Используемые препараты способствовали также увеличению урожайных показателей в сорте Чайка на варианте Азотовит1 л/га Фосфатовит1 л/га РауАктив 1 л/га с урожайностью 18,8 ц/га и Рапсодия 19,5 ц/га, по сравнению с контрольным вариантом.The article deals with the use of modern liquid fertilizers in the non-Chernozem zone of Russia. Recently, the interests of consumers have increased, agro-industrial enterprises annually make additions to the technology of growing oilseeds and their processing. The aim of the research was to study the effect of foliar fertilizing with multicomponent liquid fertilizers in two phases of vegetation, in white mustard crops. In the conditions of field experiments researches of features of growth and development of mustard white at use of a complex of fertilizers are carried out. In studies of complex liquid fertilizer has resulted in more intensive growth of plants, increasing the performance of photosynthesis. The maximum number of seeds was obtained by the cultivar Lucia, at the option Azotovit 1 l/ha Fosfatovit 1 l/ha RauActive 1 l/ha and 21.2 t/ha. And also used drugs contributed to the increase of productive indicators in grade Seagull, at the option Azotovit 1 l/ha Fosfatovit 1 l/ha RauActive 1 l/ha with a yield of 18.8 t/ha and the Rhapsody is 19.5 C/ha compared to control variant.

The paper presents the results of the analysis of demographic and medico-social data characterizing the dynamics of morbidity and mortality from environmental diseases, in particular, diseases of the cardiovascular system. The trend of negative natural population growth was revealed, amounting to -6.9 per 1,000 persons by 2019. The number of patients with cardiovascular diseases was 13 817,4 persons, with the overwhelming majority of the working-age population (9020,2 persons). Ischemic heart disease had the largest share in the structure of the studied diseases (62,25 %). There was also a decrease in life expectancy over the past 30 years and an increase in mortality of young and middle-aged people.
