The results of three-year research of “Nota” winter wheat variety growing techniques intensification influ-ence on mineral nitrogen dynamics in soil, according to vegetation periods, predecessor being corn, are pre-sented
The reaction of winter wheat cultivar ‘Antonina’ on the level of fertility and doses of fertilizers on crop productivity was studied. Investigations are carried out in multivariate 11 –course crop and grain-grass rotation stationary: factor ‘A’- the fertility of the soil; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil cultivation: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. On the basis of proven researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased and nitrogen - up to 140 kg per hectare. The increase in yield is due the rise of the quantity of grains per ear and weight of grain per ear
The questions of energy and fuel saving as well as the problem of their substitute with renewable sources are in the focus of the scientists all over the world. At present, the most actual task is the efficient use of fuel wood, especially low-grade invaluable wood and wood wastes. The article considers the regional characteristics and opportunities for wood biomass harvesting in the Voronezh region
The article deals with the issue of improving the
profitability of sheep breeding by using improved
mutant genotypes in the breeding system. The results
of studies of the main indicators of economic-useful
traits are given, the dynamics of growth, level and
quality of wool productivity of sheep of improved
genotypes obtained on the basis of such breeds as
Soviet merino and Stavropolskaya, as well as firstgeneration
daughters cultivated in themselves are
estimated. It was found that at birth, the live weight in
the groups of the 3 group (the breeding of half-blooded
hybrids "in oneself") was higher than that of the
females from the 1 and 2 groups, respectively, by 0.50
kg, or 13.1%, and by 0.20 kg or 5.2% (P> 0.95). At a
more senior age, the young, having a large live mass at
birth, retained its rank position. The highest indicator
of the cutting of physical wool was observed in animals
of the 2 group, obtained as a result of the use of sheepproducers
of Stavropolskaya breed on sheep of the
Soviet merino. The parameters of the 1 and 3 group
were lower by 0.6 kg - 12.3% and 0.17 kg - 3.5% (P>
0.95), respectively. The conclusion is made that the use
of sheep-producers of the Stavropolskaya breed on the
uterus of the Soviet merinos breed had a positive effect
on the wool productivity and the live weight of the
hybrid offspring. Further breeding of half-blooded
hybrids “in oneself” showed the possibility of
reproducing improved genotypes without losing the
acquired qualities
Based on a comparative analysis of the level of
productivity in the agrarian sector of Russia and the
leading countries in the world economy, the main
trends and factors affecting the growth of this indicator
were revealed. One the main reasons for low
productivity is the technical and technological
backwardness. In this regard, productivity gains can be
achieved by improving the employment and
organizational-technological innovation. We have
comprehensively illuminated the problem of labor
motivation. Based on our own researches and data
from agrarian scientists the ways of its strengthening
were traced. Also, there was highlighted highly
motivated work in the family farms, which is not just a
form of entrepreneurial employment based on private
ownership of the means of production and the use of
familial form of labor, but also the lifestyle of the rural
man. We must not forget that the main motivation to
work lies not only in its pay, but also in the education
of people and traditions. It highlights the role of social
support of rural youth and the need for radical
improvement of social infrastructure. For the selfassertion
of the individual, which is especially
important for young men, the person should see a
sense of ownership, initiative, independence,
participation in decision-making and the distribution of
income. These qualities are fully manifested in the
family livestock farms and other forms of small
business. Work on yourself is the most reliable social
protection
The article describes the performance analysis of disc harrows and harrows. The basic types and their purpose have been presented. Particular attention is paid to the peculiarities of optimization of geometrical and operational parameters of spherical disks, depending on soil conditions
The article describes the history of the institute called "Magarach" and the formation of the world's ampelographic collections in the Crimea and Kuban, provides data on the genetic diversity of the original parent Crimean collection of grape, carries out the impact of its long-term ampelo-breeding and genetic work. We have found the best ampelo-genetic rennets, both in the Crimea (zoned in Russia and abroad varieties of Academician Avidzba, Pervanets Magaracha, Jubilee Magarach, Antei magarachsky, Nimrang ustoichivii, Podarok Magaracha, Riesling Magaracha Novoukrainsky Rannii, Granatovii Magaracha, Krymchanin, Rkatsiteli Magaracha, Spartanets Magaracha, Tavkveri Magaracha, Citronnii Magaracha, promising varieties Livya, Solnetchnaja grozd, etc..) and in the Kuban region. Magarach ampelographic collection was and still is the parent of many national collections of gene pools of, the former Soviet republics, including the Russian Federation as well: Anapa ampelographic collection in the North Caucasus NIISiV has 3356 samples collected from 41 countries, including ones from the institute of "Magarach" (about 40%). Using its base we had a comprehensive biological and economic evaluation of the outstanding genotypes for ampelo-genetic and clonal selection – such as zoned Bogotyanovsky, Helios, Dolgogdannii, Kubattik, Libya K, Arathi, Preobragenie, Rochefort K, Chrizolit, Citrine, Anthracite, promising varieties Annie, Baikonur, Gourmet Kra, Memory Master Nesvet Gift, Jubilee Novocherkasska, etc.
There was considered the foreign country experience of state regulation of agrarian sphere. There was conducted the comparative analysis of Russian and foreign agricultural taxation
For the last few years in the world market, the rise in prices for the majority of kinds of agricultural produc-tion and foodstuff was observed. It was defined by a combination both long-term structural, and various short-term factors. It, first of all, increase of demand for the foodstuff, pushed by economic lifting in devel-oping countries, adverse weather conditions in a num-ber of the states – the main manufacturers of agricul-tural crops. All it has negatively affected world delive-ries of the foodstuffs and promoted a rise in prices for it. In article the current state of a world food situation is investigated, the reasons of the crisis phenomena in the given sphere, influencing the further existence of all civilization are allocated. The author has tried to predict consequences and the prospects of world food crisis allowing to the full to estimate that negative factors which expect mankind in intermediate term prospect
In the article the investments are the fundamental part of development of the economy of different countries as developed, and developing. The investment activity defines a basis of safe development of world economy, and also promotes determination of prospects for carrying out modernization and diversification of economy of various countries of the world. The value of foreign investments comes down to the international division of the capital, and also to searches of more favorable ways of receiving profit on economic activity abroad, than in the country of the investor. The role of foreign investments comes down to development of national economy, generally, and, in particular, recipients of these investments (the enterprises, productions, etc.). It is very favorable to a country to receive from abroad foreign investments as they develop their productions, new innovative productions appear, and also taxes come to the national budget. In this article an assessment of the world market of investments in 2015 is given. The system analysis of prospects and tendencies of development of the world market of investments in the conditions of cyclic fluctuations of world economy is carried out. The dynamics of annual streams of foreign investments into economy of Russia is considered. The consequences of sanctions of the USA and Europe entered in 2014 are reflected and their influence on investment climate of Russia is designated. The tendencies of reduction of foreign investments in the Russian economy are designated. The main problems in the production and social sphere are also revealed. Necessary terms on improvement of investment appeal of the Russian Federation are offered
