he distribution of sparganosis in the biosystems of the Central Chernozem region of the Russian Federation has been studied, material on the ecology, biology and distribution of sparganum has been collected in various territorial units of the CCR, infection of wild animals with both mature and larval forms Spirometra erinaceieuropaei (Rudolphi, 1819) has been determined. For the first time procercoids, spirometers were found in the intermediate host Ciclops strenuus(Fischer, 1851).The strongest water semination of surface water bodies was observed in the Rylsky district (Kursk region). 15 out of 133 (12.7%) studied water samples contained eggs of sparganum. We suggest that the appearance of sparganum eggs in surface water bodies is caused by washing off of sparganum eggs by rain. The largest numbers of infected Cyclops are found in Kursk, Voronezh and Tambov regions – 38 (9,84%), 21 (10,99%) и 23 (7,74%) respectively. We examined 275 animals within the study of sparganum (second larval stages) infestation of additional hosts: infected specimens were discovered in Kursk, Voronezh, Lipetsk and Tambov regions. Sparganosis was detected in two wild boars and eight grass snakes in Karachanskiy district of the Belgorod region, two grass snakes in the Usmansky district of Lipetsk region and five grass snakes in Morshansky district of the Tambov region.

The article is devoted to the study of conformities to law of accumulation of barrel wood stock and change of the age sanitary state of brittle willow (Salix fragilis L.) stands, growing on the banks of the middle and small rivers. Research was conducted on the example of the test areas, set in August, 2010, in flood bottom of Shchigor River, Shchigor district, Kursk region. It is educed, that the largest stands of brittle willow are in wet habitat with flow ground waters in flood bottom.

In 2020, the 75th anniversary of Victory in the Great Patriotic War was celebrated. Many soldiers and did not survive to see the end of the war. It is important that people living now remember and honor those who gave their lives for the freedom and independence of our country and those who came from the war in difficult conditions to restore the national economy of the country. In memory of those who courageously defended the independence of our great country, we named a new apple cultivar ‘Den Pobedy’ (Victory Day), which took 33 years to create. In 2020, this cultivar was included in the State Register of breeding achievements and it is recommended for cultivation in the Central-Chernozem region including Belgorod, Voronezh, Kursk, Lipetzk, Orel and Tambov regions. This cultivar was developed by crossing are quite commonly known winter cultivar ‘Veteran’ and foreign cultivar ‘Horcout’. Trees have a drooping crown. The main branches are curves. A characteristic feature of this cultivar is that the branches from the trunk depart at an angle close to straight. The main number of fruits is located on short fruit formations. Fruits are of medium weight (140 g), conical, wide-ribbed. The main color of the fruit at the time of harvest is greenish. The cover color occupies most of the surface of the fruit in the form of red blush. The fruit flesh is white, greenish of average density. The appearance (attractiveness) of the fruit is estimated at 4.4 points, and the taste - at 4.3 points (5-point rating). Fruits contain 14.7 % of sugars and 9.2 mg/100 g of ascorbic acid (vitamin C). Harvest in Orel region is in mid-September, the consumer period of fruits is until mid-March. The cultivar regularly bears fruit and has high product and consumer qualities.

The ecological parameters like moisture (F) and mineral nitrogen soil enrichment (N) were assessed using the Ellenberg ecological scales (Ellenberg, 1974).

The aim of the study is to find out the feasibility of including green manured fallow in specialized sugar beet crop rotations by comparing necessary assessment indicators with their values in a traditional crop rotation with black fallow against the background of unequal fertilization levels. The study was based on the analysis of experimental data from a long-term stationary experiment, laid out simultaneously in all fields and variants on typical chernozem in triplicate. The results are as follows: within the same fertilization levels, no significant differences in the yield of winter wheat (sugar beet precursor) were revealed, and the yield of sugar beet in a crop rotation with green manured fallow was stably higher (no more than 5 to 7%), an increase in yield relative to the control fertilizer variant (6 tons of manure per hectare per year) against the background of a double rate of manure in combination with mineral fertilizers amounted to 21.7 to 23.4% for wheat and 14.3 to 15.6% for beets with an increase in the productivity of crop rotations (in natural and value terms) by 1.2 times, but an increase in costs by 1.3 times caused an absolute decrease in the level of profitability by 23 to 25%. Differences in the assessment indicators for specific fertilization variants increased over time due to an unequal degree of soil fertility reproduction, and therefore in the fifth cycle of the crop rotation with black fallow turned out to be 1.1 to 1.3 times greater than in the green manured rotation.
