Description
The quality of the seed largely depends on the value of the future crop. For sowing, it is necessary to use seeds with high sowing qualities. This article is devoted to the study of the formation of high-quality seed of new varieties of winter barley, depending on the controlled compaction of crops. The paper describes in detail the importance of sowing qualities of seeds for the formation of high productivity of barley crops. The questions of influence of different seeding rates on laboratory and field germination of seeds are considered. The correlation between the four variants of seeding rates and field and laboratory germination was determined. The purity of seeds of winter barley varieties Kubagro – 1 and Kubagro – 3 was studied and it was determined that the change in the density of the formed stem does not affect the purity of seeds of these varieties. The use of highly productive seeds for sowing and further qualitative cleaning of the obtained grain contributes to the production of seed material with high purity. When considering the weight of 1000 grains in the studied varieties, it was determined that with an increase in the number of productive stems per unit area and a decrease in the area of plant nutrition, both varieties reduced the mass of grains. The highest rates of weight of 1000 grains were determined when sowing with the norm of 3.5 million germinating seeds per 1 ha, such a pattern was observed for both varieties

Description
This article reviews the results of studies on the impact of the nutrition background and the use of the Bereke GN growth stimulator on the yield and quality of early ripe potato variety Marabell in southern Kyrgyzstan. Early potato yields were largely dependent on the use of the Bereke GN growth stimulant. The highest yield was identified with the integrated use of a growth stimulator provided the planned yield, and averaged 29.97 t/ha. Also, in the experiments conducted, the yield of early potatoes was largely dependent on the climatic conditions of the year under study. The structure of the crop of early potatoes has been analyzed. In case of complex application of growth stimulator, also in case of treatment of seed tubers with growth stimulant, thickness of early potato plants is increased and on average in three years there was an increase by 0.32 and 0.52 thousand bushes per 1 ha. The structure and marketability of the early potato harvest were analyzed in detail, depending on the background of nutrition and the method of application of the Bereke GN growth stimulator

05.20.00 Processes and machines of agroengineering systems
DescriptionThe article considers manufacturing techniques and assembling screw propellers of transport vehicles for rice and fish farms. The increase in technological capabilities, reliability and carrying capacity of transport vehicles is achieved by making the propeller screw, with the possibility of its rotation. We called such propellers screw propellers, since along their perimeter along the entire length, multiple-curved curved surfaces are formed in the form of helical grooves of various configurations, sizes and shapes. The spatial form of the screw propellers is made with screw surfaces in the form of helical grooves, which ensures that the transport machines for rice and fish farms are conveyed on land, on water, through swampy and difficult terrain at a sufficiently high speed. As a result of the work performed, not only the designs of screw propellers and their classification were proposed, in which there is a general principle that allows the development of still unknown structures of propellers, but also their manufacturing techniques. The design of screw propellers was performed using the KOMPAS-3D software package using descriptive geometry and engineering graphics

PNEUMATIC SLIT SPRAYER PARAMETERS STUDY
05.20.00 Processes and machines of agroengineering systems
DescriptionAs a result of scientific analysis of the effective plant protection by spraying them with protective-stimulating liquids, the most progressive pneumohydraulic processing method was chosen, enabling the use of a wide mode range. The proposed pneumatic sprayer design can be used to equip sprayers, pollinators and combined units to perform basic operations with the use of pesticides and fertilizers. Using liquid crushing through exposure to working fluid flowing from the feeding tubes of sprayers (jets) with a high-speed air jet, it was possible to carry out the spraying process in a low-volume and ultra-small-volume way in a highly dispersive airborne jets. To study the air-borne jet parameters, providing the working fluid spraying quality as a polydisperse system, we have used a probabilistic-statistical analysis method. It studies variation range of signs according to the classes. Theoretically, the air-borne jet forming process by a pneumatic slit sprayer was considered. Using the three-factor central composite rotatable uniform plan (CURUP), the influence of three factors (surge tank position in cm, air pressure MPa and the feeding tube inclination angle in degrees) on the sprayer performance and the surface response on the working fluid median-mass diameter was determined. It was found that the response surfaces have a form of a paraboloid, the extremum of which is observed at an air pressure of 0.15 MPa (the center of the plan) and the tube installation angle in the spray housing equal to 60 degrees with the middle surge tank position. The maximum coating density of the treated object was 95 pieces / cm2 at the same position of the surge tank and air pressure in the pneumatic line of 0.3 MPa. It was proved that ultra-low volume spraying can be carried out in wide ranges of initial data while observing spraying quality requirements according to the drop median-mass diameter, the average coating density and their distribution uniformity

COGNITIVE VETERINARY – DIGITAL SOCIETY VETERINARY: THE DEFINITION OF BASIC CONCEPTS
06.02.00 Veterinary and Husbandry
DescriptionThere are many opinions on the question of what kind of society we live in at the beginning of the XXI century. Previously, it was believed that this is a post-industrial society. There was even an opinion that it would be a society of developed socialism or even a communist society. After that, the opinion on this has changed. First, modern society was called the information society, and then the society based on knowledge. The latest news in this area is that it seems that modern society is a digital society, that is, a society, based on digital technologies, digital communications, digital information processing and transmission technologies, as well as digital artificial intelligence technologies. In a digital society and science people must move to digital intelligent research technologies. In particular, the question arises as to whether veterinary medicine in a digital society should not also become cognitive veterinary medicine. This work is devoted to a detailed and reasoned (according to the authors) answer to this question. The methodology and terminology in this new field is not yet established and is not generally accepted. Therefore, in this work a lot of attention is paid to the logic and methodology of scientific knowledge, terminological issues and definitions of concepts
