“…The high value of leguminous crops is also related to the fact that they are endowed with significant biological and economic properties, since the nodule bacteria belonging to the genus Rizobium developed on their roots are able to bind/fix the free atmospheric nitrogen in the soil and to enrich the soils during the vegetation period with averagely 40-100 kg/ha biological nitrogen, at the same time improving the soil microflora and promoting the increase of soil fertility [2,3,7]:…”

The article presents the results of breeding new leguminous crop varieties at the Scientific Center of Agriculture of the Republic of Armenia and the study results related to their testing and introduction in the piedmont and mountainous zones of the republic. Upon the findings of field experiments and laboratory research conducted throughout 2020-2022, it has been disclosed that the piedmont and mountainous zones of the republic are quite favorable for the growth and development of new varieties of chickpea (Stella), lentil (Erebuni), pea (Kangun) and groundnut (Arina), which were bred at the scientific center with further subjection to state varietal testing. Meanwhile, through the study results, it has been proved, that all mentioned varieties have ensured higher yield capacity and protein content as compared to other regionalized crops in those zones, and thus, it has been recommended to introduce them in a wide range of farm households for further cultivation.

This paper shows the results of the study of the effect of temperature on the coagulation processes in the hemostasis of cows and calves. Purpose of the work: comparison of the results of the study of the indicators of the coagulation system of blood of cows and calves of the black-and-brown breed, obtained with the use of medical and veterinary coagulometer, taking into account the age of the animal and its body temperature. The study was conducted in the Vologda region of Russia. The following coagulogram parameters were analyzed: thrombin time, prothrombin time, activated partial thromboplastin time, fibrinogen count. It was found that at physiological temperature on a veterinary coagulometer in the plasma of cows there is a reliable increase in thrombin time by 2.2 times, decrease in prothrombin time by 32.5%, increase in activated partial thromboplastin time by 11.2%, increase in the amount of fibrinogen by 315.4%; in calf plasma - decrease of thrombin time by 7.8%, increase of prothrombin time by 6.2%, increase of activated partial thromboplastin time by 20.9%, increase of fibrinogen amount by 347.6% in comparison with the results obtained during standard incubation at 37°C. The correlation between hemostasis indicators and temperature factor in cows was noticeable (thrombin time, fibrinogen), in calves negative moderate for thromboplastin time, moderate for activated partial thromboplastin time and noticeable for prothrombin time and fibrinogen. The study of coagulation processes in cows and calves using a medical coagulometer led to the results that differ significantly from the reactions occurring in the organism at physiological body temperature. Taking into account the results of the study, it is possible to consider a veterinary coagulometer with the possibility of setting the necessary temperature as a device quite suitable for adequate assessment of hemostasiological parameters in cattle.

Considering the current increase in anthropogenic pollution of the environment, it becomes necessary to monitor the qualitative and quantitative aspects of the impact of pollution on various biological objects. Of great practical interest are the toxic effects of technogenic discharges on various hydrobionts and the basic mechanisms of their development in macrophyte plants. In this regard, this work studied the influence of heavy metal ions, anionic synthetic surfactants and their combinations on the activity of the main antioxidant enzymes in the tissues of Ceratophyllum demersum and Egeria densa. An experiment was conducted to assess changes in the freshwater macrophytes Ceratophyllum demersum and Egeria densa. The activity of antioxidant enzymes was taken into account: peroxidase, polyphenol oxidase, ascorbate oxidase and catalase. Their activity was assessed basally and in response to chemical stressors (100 µmol/l lead ions, 1% solution of anionic synthetic surfactants) individually and in combination with different exposures to toxic substances. The identified features of enzymatic activity in the tissues of aquatic macrophytes indicate different levels and power of their antioxidant protection. It has been noted that the activity of antioxidant enzymes when plants are exposed to certain types of pollutants and their combinations is determined by the chemical nature of the pollutant, the mechanism of its action on the plant organism, the duration of exposure and the localization of these enzymes in cell compartments.
