This article discusses the results of research on the effect of soil treatment on agro-physical performance and productivity of major field crops. The task of the research was to determine the impact of primary tillage (moldboard plowing), surface treatment (minimum) and zero (direct seeding) is factor A, fertilizers – B, and herbicides as factor C for agro-physical properties of soil. We have found that high density led to a significant increase in the proportion of the stone faction in the structural composition of the soil. Deterioration of the agro-physical properties while minimizing soil tillage has negatively affected water, air and food regimes under crops rotation. When all methods of soil tillage are applied, the moisture reserves in the 0-200 cm layer in early spring had the lowest values of moisture-holding capacity (230-272 mm) and were defined by the features of weather conditions and past cultures. At the time of sowing, their number decreased by 12% (203-241 mm). The most economical way of spending moisture was shown by plants on the moldboard tillage. In autumn, fewer weeds (7-11 PCs/m2) there were in the options for ploughing. When the surface and zero ways of soil treatments were applied, their number for 1 m2 was 1.2-1.9 times bigger. We effectively eliminated weeds only when applying herbicides. Different crop cultures reacted differently to minimizing the tillage. The greatest reduction in yield was observed when applied surface and zero tillage in cultivated crops. Thus, studies have shown that in order to obtain maximum yields of field crops of crop rotation, reducing production costs, there must be a rational combination of deep or conventional plough tillage for surface or zero tilled for grain crops
The problem of the optimal distribution of production tasks is one of the important problems of effective planning of processes associated with production at the enterprise. However, the classical approach to solving this problem becomes of little use when the individual stages of the production process are performed sequentially and in the case when it is necessary to take into account the structural features of the technological processes of the enterprise. Purpose of work: to develop a methodology for minimizing costs in the distribution of production tasks, taking into account the structural features of the technological processes of the enterprise. We built a multicriteria discrete optimization model for the distribution of production tasks according to the structure of production elements. One of the methods based on the proposed model is proposed, which allows to identify groups consisting of four elements in the production structure of the enterprise. The model is built using a network design which are pre-fractal graphs. The use of pre-fractal graphs allows you to naturally represent the structure of production and technological links of the elements of the production system of large enterprises. The results of the work is the developed effective methodology for solving the problem of the network distribution of production tasks, taking into account the structural features of technological processes at the enterprise, the economic effect of which is to minimize resource costs. Based on the constructed model, we can develop automated means of monitoring and managing the production processes of a company
In the article, the maintenance of heavy metals in fertilizers is resulted. The quantity of the years providing ecologically safe entering of mineral fertilizers before excess of maximum-permissible concentration of heavy metals in soil is calculated. The balance of heavy metals as micro – and ultra microelements in leached black soil is resulted
The studies have determined the effect of bentonite clay, vitamin complex "microvan Blend" and BAKD of local raw materials for the viability, the growth and the development of the young rearing flocks of the “Hisex brown" egg cross. To improve the quality of the grown rearing flocks and pullets increased yield, egg poultry farms were proposed to use the bioactive feed additive (BFA) made from local cheap raw materials (bentonite clay, sunflower oil, drug-soluble vitamins A, D3, E and antioxidants)
The analysis of milk technological properties of black-motley cows of both domestic and Dutch selection was conducted. It was established that the composition and technological properties of cow’s milk of both the domestic and Dutch selection meets the modern requirements to the main dairy products
In the article, we conducted an experimental study of the process of ultrafiltration milk serum on the unit of coil type and identified main patterns of this process
The article presents the comparative assessment of
economic traits of Holstein cows of various ecogenetic
types in the Volgograd region, the Russian
Federation. The study of adaptive ability of Holstein
cattle imported from the United States (245 heads),
Denmark (245 heads), Germany (386 heads), and
Australia (250 heads) has been carried out based on
breeding plant OOO "Donskoye" in Russia since 2006.
The milk producing ability of the animals was studied
during the period of first three lactations. The cows
imported from the United States showed the maximum
productivity. The cows from the USA and Germany
were registered to have the highest fat content in milk.
The mathematical modeling for predicting production
processes revealed that with respect to the milk yield,
the Holsteins of Danish selection were superior to the
cows of American, German, and Australian selections
by the fifth lactation. The high correlation between the
milk yield and the body weight, as well as between the
body weight and the fat content of milk from Holstein
cows of various selections has been established. The
cows of Danish, German, and Australian selections
showed a positive correlation between economic traits
and genetic parameters for the period of three
lactations. The cows from Australia have been proved
to have higher indices of protein composition of milk
(the total nitrogen content, the amount of essential
amino acids). The level of the adaptive ability of the
animals of the same breed but different eco-genetic
types has been found to be stable
The article is devoted to the military and
administrative activities in the Caucasus in 1838–1842
y. one of the Royal Governors-Evgeny Aleksandrovich
Golovin. The author concludes that as a Russian
Patriot and aiming initially to make the Caucasus the
Russian spirit and legal institutions, Golovin began
gradually local features, and at the end of his
Administration Region tried to combine central
traditions with peripheral. His transformations were
appraised only after Evgeniy Aleksandrovich had left
Transcaucasia. For instance, in Tiflis they started
building more European-style constructions on
wastelands, erected causeways, pavements and pools
with clean mountain water. With its extraordinary
combination of the East and the West Tiflis turned into
one of the most interesting and largest cities of Russia.
As a truly Russian nobleman, General Golovin liked
living luxuriously, openly and hospitably. The best
representatives of the local society were welcomed in
his house in a warm-hearted and friendly manner,
which caused an unconscious sensation of gratitude
and left a favourable impression. Preliminary analysis
of activity of E.A. Golovin in Transcaucasia gives no
grounds for assessments which are extremely negative
or idealise the Chief Executive. Yet E.A. Golovin
managed to be remembered as a reformer and
facilitator of Transcaucasia whose numerous initiatives
were developed by his successors: M. S. Vorontsov,
A. I. Baryatinskiy, Grand Duke Mikhail Nikolaevich
and others
The development of the political, the military and the economic power of the Russian Federation is impossible without development of patriotism and without stirring up the most important part of military-patriotic education of youth, including, of course, cadets of maritime colleges. Nowadays, the patriotism is demanded by society as a state ideology, as a most important condition and the way of spiritual and economic revival of Russia; it’s demanded as a way to unite and consolidate the entire population of Russia and as the answer to provocation from western countries seeking to weakening of Russia and finally to the collapse of the Russian world. Patriotism can be understood as a moral-political principle, social feeling, that consist of love and devotion to Fatherland, pride for it’s past and present, tendency to protect the interests of Homeland. Patriotism is expressed in love and devotion to its own Homeland, native land and its own nation, its history and culture. In present conditions, the most important direction and formation of patriotic qualities among maritime cadets can and is to be military-patriotic education, carried out on a base of regulatory documents, heroic history or Fatherland, military traditions of army and navy. Loyalty to the Fatherland, sincere love to the own country, moral-psychological and military-professional alacrity to armed protection of the Fatherland in the armed forces of the Russian Federation- it is quintessence of military – patriotic education and so it differs from patriotic education of Russian citizens. In the article it is considered the core of the military-patriotical education, based on analysis of local scientists’ views; we have formulated the goal, the tasks and the pedagogic conditions of military-patriotic education of maritime cadets; we have made an attempt to give author’s definition the term of “maritime college military-patriotic education of cadets”
