05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
The article presents results of theoretical and experimental studies on the justification and experimental confirmation of the influence of hydraulic seeding process modes on the parameters of row seeding technology for seedling crops. It is hypothesized that it is possible to ensure a uniform depth of seeding within 0.5...1.5 mm by feeding seeds into the soil by hydraulic means using a liquid. We have compiled a nomogram of the influence of the height of the initial level of the liquid and its density on the amount of pressure exerted by it on the soil. It was found that the pressure of the polydisperse system on the soil increases with both the density of the liquid and the height of the initial liquid level. Experimental studies have been conducted to study the effect of the pressure exerted by the liquid on the soil and the speed of the drill on the depth of furrow formation and the depth of wetting the soil. The article determines empirical dependences of furrow depth on the pressure exerted on it for different types of soils. It is found that the depth of soil wetting decreases with increasing speed of the drill

GROWTH AND DEVELOPMENT OF SUGAR CORN DEPENDING ON NITROGEN FERTILIZERS
06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article provides an overview of the results of a study of the effect of nitrogen fertilizers (sowing and top dressing) on the growth and development of sugar corn plants. The object of research was the mid-early hybrid of corn called Krasnodar Sugar 280 NE (FAO 280). In the experiment, 2 factors were studied: factor Ā - sowing nitrogen fertilizer (b / b (k), 15 and 30 kg.d.v / ha), factor B - root nitrogen top dressing (b / b (k), 15 and 30 kg.dv./ha). The total area of the plot is 20 m2, the accounting area is 10 m2. The number of rows in the plot is only 4, including accounting - 2. The plots are systematically placed. In the fall, the main fertilizer was applied in the background at a dose of N30P60K60, under plowing. Repeating four times. The predecessor is winter wheat. The counts and observations in the experiment were carried out according to generally accepted methods. Studies have established that the phases of “seedlings” and “5-6 leaves” did not depend on nitrogen fertilizers. The “panicle panning” phase in the variants with the introduction of nitrogen occurred 2 days later, and the phase "milk ripeness on the cob" - for 1 day. The height of the plants of the control variant was 202 cm. With an increase in the dose of nitrogen, the height of the plants of sweet corn increased. The maximum (12 cm higher) plant height was on the option using N30 for sowing and root dressing

05.13.18 Mathematical modeling, numerical methods and software complexes
Description
This work continues the series of works written by the author on the application of modern scientific methods in the study of human consciousness. In 1979-1981, two monographs were written devoted to higher forms of consciousness, the prospects of man, technology and society. One of these monographs was two-volume and was called "Theoretical Foundations of the Synthesis of Quasi-Biological Robots." In these monographs the author proposed: 1) criterial periodic classification of 49 forms of consciousness, including higher forms of consciousness (HFC); 2) based on this classification, there were psychological, microsocial and technological methods of transition between various forms of consciousness, including methods of transition from the usual form of consciousness to the HFC; 3) information-functional theory of the development of technology (including the rule of improving the quality of the basis); 4) information theory of value; 5) 11 functional schemes of technical systems of future forms of society, including remote telekinetic (mental) control systems; 6) the concept of development of society in groups of socio-economic formations; 7) the concept of determining the form of human consciousness by the functional level of the technological environment; 8) mathematical and numerical modeling of the dynamics of the probability density of states of human consciousness in evolution using the theory of Markov’s random processes. In this study, we carry out a complete automated system-cognitive analysis (ASC- analysis) of the periodic criteria classification of forms of consciousness proposed by the author in 1978. To this end, the following tasks are solved in the work: cognitive structuring and formalization of the subject area; synthesis and verification of statistical and system-cognitive models (multi-parameter typification of forms of consciousness); systemic identification of forms of consciousness; their typological analysis; investigations of a simulated domain by examining its model. We have also given a detailed numerical example of solving all these problems
