CORRELATION AMONG QUANTITATIVE TRAITS OF SORGHUM GRAIN

abstract 1281704062 issue 128 pp. 931 – 940 28.04.2017 ru 572
At present, the farmers have to develop varieties and hybrids, which fully meet the requirements of agricultural production. The study of correlation among economic-valuable characteristics of grain sorghum is of great importance nowadays, as it allows optimizing plant-breeding work at its early stages. For a more productive process of developing of the initial material in breeding, it is necessary to determine the correlation among the traits to identify the strongest connections, and to conduct further work, based on the obtained data. Knowing the correlation, the estimation of timeconsuming economic trait can be replaced by the assessment of the simpler trait correlated with it. The article presents the analysis of correlation among various traits of grain sorghum. The degree and direction of the correlation have been estimated. The significant effect of the length of vegetation period on many traits has been seen. There have been also mentioned the characteristics, having an influence on a size and a number of kernels per panicle. There is a positive correlation between a size of panicle and dimensions of a leaf (length, width). Along with it there has been found a positive correlation among linier dimensions of a panicle, length and width of a leaf, a number of leaves with a number of kernels per panicle. While studying the correlation between an extension of a panicle with other traits, there has been noted a negative correlation between a length of vegetation period, length and width of a leaf, but there has been found a positive correlation with plant height. There has been found a positive effect of 1000-kernel weight, a number of kernels per panicle, a number of leaves and their dimensions on the formation of kernel weight per panicle

SIMULATION OF A POWER TRANSFORMER WORK WITH A HIGH LEVEL OF HIGHER HARMONICS

abstract 1331709003 issue 133 pp. 24 – 29 30.11.2017 ru 572
The importance of improving the quality of electrical energy was growing along with the development and wide implementation in the production of valve converters and various highperformance processing units, such as arc furnace, welding machines etc. The main causes of potential and existing non-compliances of non-sinusoidal voltages can be joining sources and non-sinusoidal reactive power sources, including resonant filters, to existing electric grids without taking into account their possible impact on the distortion of the sinusoidal voltage. Transformers are affected by the non-sinusoidal shapes of the curves of current and voltage. The effect is characterized by the fact that the harmonics of current and voltage increase transformer temperature, compared to purely sinusoidal current and voltage. The aim of this work is to study the influence of higher harmonics on power loss in power transformers. Experimental study of operation of power transformers was carried out on the developed model of the transformer substation. The experiments were conducted with different capacities of transformers that have variables in the range of 250-1000 kVA. By using programmable voltage source a sinusoidal voltage is formed containing the third, fifth, sixth, seventh, ninth and twelfth harmonics. The level of harmonics is changed in the range of 2-12 %

LONG TERM 32-YEAR-OLD APPLICATION OF FERTILIZERS FOR THE FERTILITY OF THE ORDINARY BLACK SOIL AND PRODUCTIVITY OF SUGAR BEET

abstract 1171603088 issue 117 pp. 1341 – 1356 31.03.2016 ru 573
The article deals with the effectiveness of mineral and organic fertilizers in long-term application (for more than thirty years) according to the influence on the fertility of ordinary black soil of the Western Ciscaucasia and productivity of sugar beet. The investigations were carried out in the long-term stationary experiment laid on the experimental stationary section "Severokubanskaya agricultural experimental station" of P.P. Lukyanenko Krasnodar Agricultural Research Institute. The experiment was laid simultaneously in time and space in two ten-course crop rotations and combined grain-grass tilled. In the structure of sown areas sugar beet occupied 10% of crop rotation area and was placed after the winter wheat. During three rotations it was studied: 1- control without fertilizer with natural forming level of mineral nutrition; 2- minimal dose N21P26K16 3- medium dose N43P52K33 ; 4 - N43P52K33, 5- high dose N96P104K68; 6- organo-mineral system¹ N43P52K34 + 12 t/ha of manure; 7- organo-mineral system² N20P24K34 + II-III rotations tillage of straw crop + 6 t/ha of manure; 8- medium dose P52K33; 9- medium dose N43K33; 10- medium dose N43K52. The soil which is used by organo-mineral system with increased and high standards of mineral fertilizers had higher concentration of mineral nitrogen. Long systematic application of fertilizer had more noticeable effect on soil phosphorus regime. The provision of soil by exchange potassium tended to decline from rotation to rotation. If at the completion of the first rotation the content of this battery was at the level 362,0-433,0 mg / kg of soil, in 2010, these values were 356,0-405,0 mg / kg of soil, remaining at the level of increased and high provision characterized to ordinary black-soil. Fertilizers for crop rotation provided almost equal yield increase: in the first rotation - 4,9-16,0 t / ha in the second 5,3- 17,1, the third 6,1-15,5 t / ha. In the moderate favorable for moisture and temperature conditions during the first and third rotation (hydrothermal index 0,8- 0,76), the value of sugar beet yield was 30,1-46,1 and 35,7-52,1 t / ha, in comparison with tougher conditions for the second rotation (hydrothermal index 0,41- 1,96) higher up to 2,6-6,5 9,2-16,0 t / ha. Research carried out in long-term stationary experiment showed that long-term use of fertilizers prevents to the loss of soil organic substances, supporting the humus content at the level of 3.95-3.99%, and organicsystems contribute to its reproduction to 4,01-4,21%. soil nitrogen state is stabilized. However, there is a tendency of decrease of the exchange potassium in mineral fertilizer systems. In the conditions of insufficient moisture supply of the northern zone of Krasnodar region the most applicable norm is N60P90R60, both in mineral and organic-systems, ensuring the collection of root crops within 43,0-45,2 t / ha, with an estimated amount of sugar 6,92-7, 14 t / ha. The given systems of fertilizer provide the yield of root crops 53,3-56,0 t / ha with the synthesis of sugar 8,19-8,70 t / ha. Increasing the rate of fertilizer in 2 times from medium to N120P160R120 doesn’t increase the productivity, reduce sugar content of root crop to 0.4-0.8%. It is undesirable to use fertilizer that are unbalanced in nutrition elements in which root crops yield declines from 5.4 to 19.0%, and current biological sugar from 6,1 to 25,9%

POULTRY MANURE AND ITS USE AS AN ORGANIC FERTILIZER

abstract 1281704061 issue 128 pp. 913 – 930 28.04.2017 ru 573
We have conducted a research on the poultry farm of the commodity farm of the educational and experimental farm Kuban of the Kuban State Agrarian University. The chemical analysis of various organic fertilizers is considered in the article. Also agrochemical characteristics of organic fertilizers are given. The composition and properties of the bird droppings of the farm under study were determined for comparison with other organic fertilizers: manure of cattle and pig manure. Since straw is used as the main moisture-absorbing material for composting in the farm under study, straw analyzes were carried out in terms of chemical composition and nutritional content. A chemical analysis of the content of plant nutrients in straw has been carried out. Bird droppings is valuable, a fast full fertilizer. Of all organic fertilizers, bird droppings are the most valuable, both in nutrient content and in their accessibility to plants. The nutrient content in the litter varies depending on the species of the bird, the breed, the age, the method of keeping and feeding, the type of feed and other factors. The chicken manure contains morephosphorus, nitrogen and potassium, than manure of cattle and pigs. The advantage of organic fertilizers in comparison with mineral fertilizers is their long after-effect. As fertilizer a bird droppings surpasses manure at 8-10 times and almost don't concede to equal amount of nutrients of mineral fertilizers by action on productivity of cultures. The norm of introduction of bird droppings is up to 30 times lower, than norm of introduction of manure. Agricultural areas where introduction of organic fertilizers, the list of crops under which fertilizers are introduced were considered. The received results confirm the value of organic fertilizers (bird droppings), and their application enriches the soil with necessary nutrients, increases productivity and quality of grown-up crops

CRITERIA FOR SELECTION OF KEY WORDS DURING THE FORMATION OF A SEARCH QUERY

abstract 1291705021 issue 129 pp. 237 – 254 31.05.2017 ru 573
This article was written in the mainstream of modern Lingua-pragmatic research and is dedicated to the analysis of the criteria for selecting keywords during the formation of a search query. The choice of this type of Internet communication is due, first of all, to the fact that the search query is a text consisting entirely of keywords, aside from that search query is used in everyday speech practice regularly and often. The article suggests possible criteria for the selection of keywords; we have developed a technique for analyzing the search query in a communicative aspect. The main methods studies were continuous sampling of the material, linguistic experiment and semantic and communicative analysis. Particular attention is paid to the difficulties arising in the analysis of requests in which the producer's intention is not clearly expressed. The results of the research are important for understanding the linguistic essence of the keyword, the principles of the formation of search queries and can be used in the analysis of keywords in different types of texts. Practical significance of the research is that taking into account the given criteria in the choice of keywords allows reducing the communicative risks arising in the process of the search query formation

DISTRIBUTIONS OF REAL STATISTICAL DATA ARE NOT NORMAL

abstract 1171603003 issue 117 pp. 73 – 92 31.03.2016 ru 574
In the training courses on the theory of probability and mathematical statistics there are various parametric families of distributions of numerical random variables considered. Namely, we have been studying the families of normal distributions, log-normal distributions, exponential distributions, gamma distributions, Weibull-Gnedenko distributions, etc. All of them depend on one, two or three parameters. Therefore, for a complete description of the distribution it is sufficient to know or estimate one, two or three numbers. Parametric theory of mathematical statistics is widely developed, where it is assumed that the distribution of observations belong to one or another parametric family of distributions. This tradition comes from Karl Pearson, who in the early twentieth century proposed the use of four parametric family of distributions. The above families of distributions - are the subsets of a four-parametric family of Pearson. Unfortunately, parametric families exist only in the minds of the authors of textbooks on probability theory and mathematical statistics. In real life, they are not. Therefore, modern applied statistics and econometrics mainly use non-parametric methods, in which the distribution of observations can have arbitrary form. First, on an example of a normal distribution, we are discussing the impossibility of practical use of parametric families of distributions to describe specific statistical data. We give the results of research of metrologists and estimation of convergence in limit theorems. Then we discuss how the parametric methods can use for reject outlying observations. It is very unstable the significance levels for a fixed rejection rule and the parameter of the rejection rules for a fixed level of significance. Consequently, the rejection of the classic rules of mathematical statistics is not sciencebased

DEVELOPMENT WORK ON THE CREATION OF ROBOTICS FARMLAND

abstract 1191605035 issue 119 pp. 488 – 502 31.05.2016 ru 574
The article gives a brief historical overview of the development work on the creation of agricultural robots. We also give characteristics of the market for robots, with their descriptions since 2002 onwards. The work presents main problems when creating agricultural robots, with more detailed features such as orientation in space using machine vision tools, as well as video surveillance to identify and recognize the characteristics of plants. Continuous, panoramicallythree-dimensional tracking of each plant can be provided by using a video network, able to distinguish between separate plants within the field of view of the cameras, lined up in particularly targeted technological points. Custom video shooting is possible for individual plants, with the aim of identifying deviations in development, degree of maturation, detection of disease and other technological purposes. It is shown that positioning and motion control of the technological trajectory can be carried out using satellite navigation systems either using ground positioning, including machine vision and targeting laser, for example pathpointer or sensor barriers. For detection, identification and positioning we commonly use satellite navigation GPS system (mainly for monitoring vehicles and agricultural units). As well as television and digital video surveillance and positioning system in real-timeRTLS, but each of these systems has its limitations. Network wireless local positioning RFID (Radio-frequency identification) is used for various purposes in a variety of applications, allowing you to monitor the location and movement of objects and reliably identify them both outside and inside the premises. But none of these systems could possibly accomplish the task completely. The solution may be sharing the listed systems. This integration offers opportunities not available for separate systems. This article describes a platform with a caterpillar engine, as the basis of unmanned robot for farmlands

PREDICTIVE EVALUATION OF THE EXPECTED RICE YIELD IN THE KUBAN REGION IN 2016-2020

abstract 1201606083 issue 120 pp. 1250 – 1265 30.06.2016 ru 574
The article presents the analysis of variation of daily mean temperatures for the period 1977-2015. Clear tendency for their increasing in pre-sowing and especially in growing period is found. Heat supply of separate months in pre-sowing period increased in the row: April-February-January-December-March, and that of growing period – in a row: May-Juny-JulySeptember-August. Presence of slight correlation (from -0,256 to 0,268) of temperatures in winter-spring months with heat supply of coming spring summer months is found. It is shown that correlation of rice yield with temperatures of pre-sowing (DecemberApril) and growing (May-September) periods varies from weak to average (from 0,016 to 0,524) with a tendency to increasing from winter months to summer ones. Use of analog method made it possible to estimate roughly the nature of t upcoming growing season of rice in the current 2016: after the abnormally warm winter one should expect the value of heat supply of summer months to be close to normal. In the physiological sense, such distribution of summer temperatures is favorable for rice. Use of one of the most effective forecast methods – smoothing the time series (method of «moving decades») – made it possible to evaluate medium-term rhythms of heat supply of rice growing season and yields. It was found that after an abnormally high level of heat supply of the growing season, marked during last decade, we should expect a decrease in spring and summer temperatures - the next attack of the "cold" cycle. If this hypothesis is confirmed, then up to 2020, and later a natural tendency for decrease in rice yields, arising from the adverse factors of temperature, will continue which should also affect the economic efficiency of the industry as a whole
