MONITORING OF THE MAIN PROPERTIES OF ORDINARY CHERNOZEM OF ROSTOV OBLAST

Posted in 2021, AGRICULTURE, Issue №9 (111) September 2021 | 0 comments

As the main means of crop production, the soil cover is an important element in monitoring studies. In the period from 1973 to 2018, studies on monitoring the properties of ordinary chernozem soils of Rostov Oblast, the distribution area of which is the Azov inclined plain, were carried out on stationary sites. This made it possible to objectively assess the dynamics of soil properties of various degrees of erosion depending on the intensity of erosion and deflation as well as human economic activity. For this purpose, an ecological profile of soil sections was laid from the watershed plateau to the foot of the slope. After analyzing the humus profile, chemical, physicochemical, physical properties of the watershed soils and slopes, the authors have come to the conclusion that their changes are caused by the intensification of human economic activity and an insufficient amount of fertilizer applied, which is the root cause of dehumification. This led to a number of other negative changes: a decrease in the supply of batteries, the number of absorbed bases, etc. On sloping lands, the process of dehumification is aggravated by the manifestation of erosion and the associated loss of the uppermost fertile soil layer and anti-erosion stability.

Posted in 2021, AGRICULTURE, Issue №9 (111) September 2021 | 0 comments

The study is aimed at examining the results of the accumulation cross breeding of Romanov and Katahdin sheep breeds. The study tests Katahdin rams imported from America. For grading up, the study uses the Romanov ewes, acclimatized for the North-Western region of Russia. The analysis of the relationship between the reproduction indicators of the Katahdin ewes of different bloodlines shows a positive correlation of the pedigree with the percentage of the yeaned ewe and the safety of the lambs for weaning (0.646; p<0.01), as well as a positive two-way correlation between the number of lambs received per one yeaned ewe and the safety of the lambs for weaning (0.719; p<0.01). At the same time, the highest level of safety of lambs for weaning was in the group ♂КТ x ♀3/4КТ×1/4РО and amounted to 98.5%. The study revealed a two-way positive correlation between the indicator of live weight at birth and during weaning from 50% to 87.5% of the pedigree of the Katahdin breed (from 0.789 to 0,920; р<0,01), which points to the effectiveness of using this type of cross breeding for the purposes of improving the meat production of the Romanov sheep before 3rd generation.

DEVELOPMENT OF AZOTOBACTER IN FARM ECOSYSTEMS SATURATED WITH GLYPHOSATE-CONTAINING HERBICIDES

Posted in 2021, AGRICULTURE, Issue №9 (111) September 2021 | 0 comments

It has been found that in the soil and climatic conditions of the south-east of the Central Black Earth economic region, the use of a glyphosate-containing herbicide of continuous action has the strongest negative effect on the soil environment in the surface layer of the soil (0-5 cm), whereas with an increase in the thickness of the studied layer to 0-20 cm, the effect of glyphosate acid on the soil biota is observed to be significantly less.

An increase in the rate of use of a glyphosate-containing drug (Tornado 500, aqueous solution) from the recommended one (3.0 l/ha) by three times (9.0 l/ha) reduces the number of azotobacter in the soil layer of 0-5 cm by 20 times.

After seven years of annual use of the herbicide Tornado 500, aqueous solution (500 g/l of glyphosate acid) at a dose of 2.5 l / ha twice during the growing season (only 35 l/ha), the number of azotobacter decreases in the surface layer of 0-5 cm in ordinary chernozem against the background with the annual use of fertilizers N60P60By60, under the main tillage, almost by three times, against the background without the use of fertilizers, seven times compared to the soil where glyphosate-containing preparations were not used.

PATHOGENS OF ANISAKIDOSIS AND THEIR LOCALIZATION IN SALTWATER FISH OF THE POPULATIONS IN THE NORTHERN REGION OF THE SEA OF OKHOTSK

Posted in 2021, AGRICULTURE, Issue №9 (111) September 2021 | 0 comments

Almost all saltwater fish of the North Sea populations are invaded by pathogens of anisakidosis, a dangerous helminthic disease transmitted to humans and animals. Currently, there are no studies being conducted in Magadan Oblast to clarify the epidemiological and epizootological significance of the fish species being harvested in the waters of the northern Okhotsk Sea. The information stated above determines the aim of the study, which is to determine the taxonomic status of the pathogens of anisakidosis, their localization and infection of fish. The article examines five species of saltwater fish (Pacific herring Clupea pallasii, saffron cod Eleginus gracilis, scale-eye plaice Acanthopsetta nadeshnyi, starry flounder Platichthys stellatus, rainbow smelt Osmerus mordax dentex) in an amount of 202 specimens caught in the northern part of the Sea of Okhotsk in the spring and summer of 2021; also, the article contains a study of the localization and degree of contamination of fish in a comparative aspect. The degree of the presence of the larvae of Anisakis simplex and Pseudoterranova decipiensin Osmerus mordax dentex amounted to 72.0%, Eleginus gracilis — 68.0%, Platichthys stellatus and Acanthopsetta nadeshnyi — 66.6%, herring — 100.0%. The average indicator of the intensity of invasion and its maximum values had significant differences at the interspecific level in the fish under study. The indicators of the toothed smelt and the stellate flounder did not have significant differences: infection intensity 1-5 (3,0) specimens and 1-3 (1,7) specimens. accordingly, the intensity of infection was higher in Eleginus gracilis and prickly flounder — infection intensity 1-12 (7.0) specimens and 5-12 (4.4) specimens, respectively. The highest values of infection intensity were observed in herring: 10-34 (15.0). The largest number of helminths is localized on the internal organs (66.9 %), body cavity – 30.8%, the muscles – 2.3 %. As a result of the conducted studies, it was concluded that smelt and flounder fish have the greatest epidemiological and epizootological significance due to the localization of anisakis larvae in the layers of the abdominal and dorsal muscles as the most consumed for food and fish processing.

Posted in 2021, AGRICULTURE, Issue №8 (110) August 2021 | 0 comments

Microalgae are a very diverse group of unicellular organisms consisting of protozoan eukaryotes and prokaryotic cyanobacteria or blue-green algae. Microalgae have a unique ecological status; while being almost ubiquitous in euphotic zones, they can occupy extreme habitats, ranging from tropical coral reefs to polar regions, and contribute to half of the photosynthetic activity of the globe. In addition, they form the basis of the food chain for more than 70% of the world’s biomass. Microalgae are a valuable ecological and biotechnological resource, and the purpose of this review is to study the use of in vitro technologies for the conservation and sustainable use of this remarkable group of organisms. The first part of the review assesses the importance of in vitro methods in the maintenance and preservation of microalgae and describes the central role of culture collections in applied algae research. The second part examines the application of microalgae technologies in vitro, particularly in the context of aquaculture and biotechnology. Special attention is paid to the use of economically important algae products, including feed for aquaculture, biomass production for the health sector, green fertilizers, pigments, vitamins, antioxidants and antimicrobial agents. The contribution of microalgae to environmental studies is also evaluated; for example, they play an important role as indicator organisms in environmental impact assessment. Similarly, special collection strains of microalgae are used to test ecotoxicity.

ON THE INFLUENCE OF THE DEGREE OF COMPACTION OF FEED GRAIN ON THE QUALITY OF FERMENTATION WHEN USING VARIOUS PREPARATIONS FOR ITS PRESERVATION

Posted in 2021, AGRICULTURE, Issue №8 (110) August 2021 | 0 comments

Similar to grass silage, the technology of canning and anaerobic storage of flattened raw grain is sufficiently studied and is widely used in practice. At the same time, the existing differences between these technologies do not allow for an immediate application of the known provisions of the silage technology to grain canning. For instance, It is not known how different degrees of grain compaction will affect the preserving properties of chemical and biological preparations. The results of the research demonstrate that powdered sulfur has the greatest positive effect on the fermentation quality of canned raw flattened barley grain with an average degree of compaction when laying for storage, providing the advantage of homofermentative lactic acid fermentation and the predominance of lactic acid in the total amount of fermentation acids as well as better acidification of feed during harvesting and storage.

AN ANALYSIS OF THE MORPHOLOGICAL STRUCTURE OF THE KATUMSKY SHEEP CARCASS

Posted in 2021, AGRICULTURE, Issue №8 (110) August 2021 | 0 comments

The article examines the indicators of the morphological structure of the carcass of rams and wethers of different ages of the Katumsky sheep breed. The study determines the intergroup differences in the coefficient of meat content and the area of the muscle eye. At the same time, the highest meat content coefficient was detected in rams aged 3 months: it amounted to6.13±0.52%, which is 16.8% more than in rams aged 6 and 18 months and 33.6-43.7% more than in wethers. Positive changes were identified in the degree of bone development in rams by the age of 18 months (the bone weight equaled 5.95±0.97 kg with the mass of the cooled carcass of 35.91±2.14 kg), in contrast to the group of wethers of this age (the bone weight was 4.42±0.37 kg with the mass of the cooled carcass of 22.4±2.85 kg). The data indicate the intensity of metabolic processes in the body, the positive dynamics of meat productivity in rams of up to 18 months of age, and in wethers of up to 4 months of age. Thus, castration of Katumsky rams at the age of 3 months at weaning is advisable when growing the wethers up to 4 months of age with subsequent sale for meat.

THE USE OF SIBERIAN PINE (PINUS SIBIRICA DU TOUR.) IN THE LANDSCAPING OF EKATERINBURG

Posted in 2021, AGRICULTURE, Issue №7 (109) July 2021 | 0 comments

On the basis of field studies with widely known proven methods, the use of sSiberian (Siberioan stone pine) (Pinus sibirica De Tour) in landscaping the city of Ekaterinburg has been analyzed. It is noted that despite the high decorative qualities and good resistance of Siberian cedar pine in an urban environment, the latter are used in very limited volumes in landscaping. The latter is explained by insufficient amount of planting material and the slow growth of Siberian cedar trees at gyoung age. This circumstance complicates the formation of landscape biogroups combining Sibierian cedar pine with other woody species.

At the same time, the excellent condition of Siberian cedar pine trees, especially in biogroups, testifies to the advisability of creating site eglandscaping objects from this tree species in parusks, squares and urban forest parus of the city. The use Siberian cedar pine will contribute to biological diversity increasing, including by attracting birds and small animals.

Since the Siberian cedar pine is an aboriginal species it doesn’t need acclimatization. It is advisable to grow planting material of Siberian cedar pine with a closed root system which will increase the survival rate of planting and reduce the number of agrotechnical cares. Planting is better for the same reasomen to carry out by with large sized planting material.

ON THE INFLUENCE OF FOREST STAND COMPOSITION ON SNOW ACCUMULATION IN THE SOUTHERN TAIGA SUBZONE OF THE URALS

Posted in 2021, AGRICULTURE, Issue №7 (109) July 2021 | 0 comments

The study conducts an analysis of the accumulation of winter precipitation under the canopy of stands of various compositions and on power lines in 16 sample areas in the southern taiga subzone of the Urals. The data on the height and density of the snow cover were obtained on the basis of a snow measurement survey carried out at the end of March, i.e. at the maximum height of the snow cover. The authors of the study used a snow measuring rail and a weight snow meter VS-43.

The research establishes that the maximum supply of snow water at the time of the beginning of snowmelt accumulates under the canopy of larch trees with an admixture of pine in the composition of the stands. Significant reserves of snow water also accumulate under the canopy of birch forests and on power lines when they are located from north to south.

The average height of the snow cover varies from 33.5 to 54.9 cm, which indicates the protection of the lower layers of vegetation from freezing. In order to accumulate winter precipitation in the stands of the southern taiga subzone, it is advisable to form mixed plantings with an admixture of larch and birch to pine. These plantings in forest parks will not only increase the stability and recreational attractiveness of the stands but also ensure the maximum accumulation of winter precipitation. The latter, in turn, will contribute to the accumulation of groundwater and the water Level of the Iset river.
