06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionIn the experiment, we have studied the effect of the use of an intelligent spreader on increasing the efficiency of nitrogen fertilizers used to feed winter wheat in ordinary chernozem. The studies were carried out in the production conditions of land use by AO SHP Kolos in the Kochubeyevsky district. In this article, we have examined the effect of a sprayer (Amazone UG 3000 Nova) and an intelligent mineral fertilizer spreader (Amazon ZA - TS - 4200) using touch sensors to determine the NDVI development index on the efficiency of nitrogen fertilizing winter wheat. Based on the experiments, it was found that, on average, over the two years of the study, the largest increase in the yield of winter wheat grains was noted in the variant with the introduction of ammonia nitrate in the first and second fertilizers using the intelligent fertilizer spreader Amazon ZA - TS - 4200 according to the NDVI - 6.53 t / ha. The highest structural indices of winter wheat grain yield were also noted in the variant with the introduction of ammonium nitrate in the first and second fertilizers using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index. So, the height of plants increased by 16.3 cm, the number of productive stems per 1 m2 by 37 pcs. The number of grains in the ear - by 5 pcs., The weight of 1000 grains - 0.8 g. According to the results of the experiments, it was established that in the conditions of land use by JSC "Agricultural Enterprise" Kolos "of the Kochubeyevsky District of the Stavropol region when planning the harvest of winter wheat - 6.5 tons / ha, it is advisable to use in the first and second top dressing of ammonium nitrate with a dose of 150 kg / ha, using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index

DescriptionThe article presents data from 3-year observations of the weather conditions influence on the effectiveness of applied fertilizers in the crops of the Yantar variety of coriander on leached black soil (chernozem) under the conditions of land use at the training and experimental station of the Stavropol State Agrarian University. The materials presented in the article indicate that the agrometeorological conditions of 2016 and 2017 as a whole were most favorable for the formation of a coriander crop. As studies have shown, the amount of precipitation during the spring-summer period of the growing season of the crop was 337 mm, which is 11% higher than the long-term average. The year 2018 in terms of climatic indicators turned out to be significantly worse than the previous two years, the amount of precipitation during the coriander vegetation period turned out to be 125 mm or 58% lower than the long-term average, which significantly affected the crop yield this year. In the most optimal agroclimatic indicators in 2016, the maximum increase in crop productivity was noted on the N60P60K60 variant - 0.49 t / ha, on the same option in moistened 2017, the increase level was 0.39 t / ha. Last year2018 was marked as extremely arid, the maximum increase in coriander yield was noted on the option with P60 and amounted to 0.35 t / ha. It was established that the maximum increase in the yield of coriander oil seeds on average in the experiment on leached chernozem was achieved with the options: P60 is 0.37 t / ha, N60P60 is 0.41 t / ha, N60P60K60 is 0.34 t / ha, which significantly higher than other fertilized experience options. The economic efficiency of the coriander seeds production, depending on the types and combinations of minerals, turned out to be most effective when applying a single mineral fertilizer, P60, compared with other options for experience, an increase in profit to 17500 rubles and the level of profitability of production by 23%

FEATURES OF TECHNICAL RISK ASSESSMENT UNDER NON-DETERMINISTIC STOCHASTIC PARAMETERS
05.20.00 Processes and machines of agroengineering systems
DescriptionThe article considers a variant of parametric representation of a complex product of single use in the process of its creation during tests, when structural failures of the product or its components in one or more parameters specified in the technical specification require modifications leading to a change in the general amount and repeating of the tests, but it is possible to reduce the volume of tests by taking into account a priori information. This is especially up-to-date while ensuring the reliability of complex single – use products, the components of which are first stages of ground tests, and only then as part of complex products-the stages of flight tests. Structural failure of any component of such a product at the stage of ground tests does not lead to such consequences as if it occurred during flight tests as part of the product. Meanwhile, the refinement of the component element of a single-use product, the structural failure of which occurred at the stage of flight tests as part of the product, and the assessment of its effectiveness, can be carried out at the stage of ground tests, in the case of consideration of a complex product in parametric form. This can significantly reduce the cost of flight testing of a complex product, in the case of effective completion of the component element of the product at the stage of ground tests, without a significant (temporary) decrease in the overall reliability of a complex single-use product

Description
The article examines the key aspects of import of food in Russia at the present stage. The relevance of this problem is necessary to the development directions of rationalization of import substitution, under condition of increase of competitiveness of domestic agricultural producers. The importance of this problem increases in recent years due to sanctions and embargoes, highlights the need for comprehensive studies in the formation of commodity composition of import substitution of food products and determining the key factors of its regulation. The work presents the analysis of dynamics of volume of imports of foodstuffs and agricultural raw materials for their production and its diversification based on import substitution. We discuss main commodity groups of food and, in particular, crop production and viticulture. In addition, we examined the major groups of goods from the point of view of the potential and opportunities for import substitution and selected those items, which, for various reasons, cannot be carried out in the Russian conditions due to climatic and other factors. As a result of the study, the authors concluded that the introduction of anti-Russian sanctions and the retaliatory embargo on imports of foreign agricultural commodities in general had a positive impact on the development of the domestic agricultural business, which is confirmed by the indices of growth of agricultural production in recent years. In addition, if there is further adequate funding of this sector, it is possible to speak about prospects of strengthening of food independence of Russia

RATIONAL PHARMACOTHERAPY FOR PANCREATITIS IN DOGS
DescriptionDiseases of the digestive system are one of the huge problems of veterinary medicine and pharmacy. This group of diseases not only affects all age groups of animals, but can occur even in newborn puppies. It is very difficult to talk about the breed predisposition to pancreatitis in animals. Pancreatitis occupies one of the leading places in the structure of digestive diseases in animals. The urgency of this veterinary problem is increasing every year. Acute pancreatitis manifests itself suddenly, most often against the background of gross violations in feeding, with the disease of the duodenum and gallbladder. In this case, there is a violation of the outflow of secretion into the ducts of the pancreas. In the tissues of the pancreas there are diffuse changes up to necrosis. Severe inflammation of the pancreas leads to a sharp deterioration in the general condition of the body, sharply reduced blood pressure. The animal is in great pain, vomiting is observed. The animal needs urgent care. The disease can be chronic. Periods of exacerbation are repeated from time to time. The owners usually do not call veterinary specialists. Since the disease is manifested by symptoms characteristic of many pathologies of the gastrointestinal tract, it is therefore difficult to diagnose. In the history of the animal there are both diarrhea and constipation, the animal has a reduced appetite, in hotel cases there is cachexia. In hematological studies, we can note an increase in sugar levels. Therefore, for the differential diagnosis of the animal, we carry out ultrasound, x-ray diagnostics all together with biochemical methods of blood tests. In the future, when choosing treatment tactics, all diseases that could accompany inflammation of the pancreas are taken into account
