The article studies the effects of different sawing rates of witer barley on crop yield. The studies were conducted on the experimental field of the Federal State Educational Institution of Higher Education in the Nizhny Novgorod State Agricultural Academy at the Novinki training experimental establishment from 2015 to 2018 on light gray forest soils. The object of research was Volzhsky Perviy variety of winter barley. We studied different sowing rates: 2, 3, 4, 5, 6, and 7 million germinating seeds per 1 hectare. The predecessor was clean fallow. On average, over 3 years of research, we observed the seeds field germination rate of 84.0-84.5%. The survival rate of plants at harvest was quite satisfactory 51.4-69.3%. We have noticed that an increase in the seeding rate from 2 to 7 million units / ha has led to a decrease in survival rate of plants by 17.9%. The highest grain yield in the experiment - 4.47 t / ha was obtained at a sowing rate of 6 million germinating seeds per 1 ha. An increase in the seeding rate from 2.0 to 7.0 million germinating seeds per 1 ha has led to an increase in the density of the productive stalk from 252 to 367 pcs / m2. The number of grains per spike in the study varied within a narrow range from 38 to 39 pieces, whereas the weight of 1000 grains varied from 32.7 to 33.8 g. We observed high spike productivity from 1.260 to 1.303 g due to the high number of grains per spike. Volzhsky Perviy variety of winter barley, showed good tillering ability when cultivated in the conditions of the Nizhny Novgorod region. The coefficient of total tillering capacity varied from 2.03 to 2.78, whereas the productive tillering capacity varied from 1.99 to 1.42
The article presents the data on the formation of the embryonic fruitfulness of central ovaries of wintering buds of the group of technical grape varieties with white berries - White Muscat; Pinot White, Chardonnay, Citron Magaracha, Pervenets Magaracha; Riesling, Viorica, Riton, Crystal in the conditions of Anapa-Taman zone. There were revealed the rates of embryonic fruitfulness of central ovaries of buds of studied cultivars and fruiting indices of vegetative shoots developed from them. In all studied grape varieties there was revealed a high percentage of fruitful buds from 84,1 in the variety of Riton at 97.2 at Viorica; and the percentage of fertile vegetative shoots from 81,8 at the variety Citron Magaracha to 97.2 in the variety White Muscat. At the leveled load of bushes, vegetative shoots and the same scheme of planting of bushes (3 x 2 m), the highest yield in terms per hectare showed the varieties Pervenets Magaracha, Viorica, Riton, Crystal, Riesling and Citron Magarach. When assessing the economic efficiency the highest net income and level of profitability were identified in the varieties of Citron Magaracha, Pervenets Magaracha, Viorica and Riton. In order to determine which buds will give us shoots with large, well-developed (well-differentiated) buds, and which will not give (weakly differentiated), it is necessary "to look inside a bud". But even already formed germs of inflorescences in the bud are able in a few days in spring or dedifferentiate or degrade depending on the influence of external conditions. Scientists have learned to use this ability to increase the maximum possible yield in years of severe damage of grape by frosts. Firstly, in frosty winters the central buds wither out. The replacing buds usually have poor fruiting and bad productivity during years. In such cases, it is more profitable to conduct a small cutting of angle buds arranged in a circle at the base of a shoot. At the beginning of the second vegetation phase, these buds will obtain the great bulk plastic substances, which will cause the dedifferentiation of rudiments of inflorescences in them. Thus, it is possible not only to restore rapidly the normal shape of a bush, but to obtain a good harvest this year
In this article we have shown the results of the study of influence pruning of different density levels on growth, yield quality and profitability of cultivation apple cv. Champion, grafted on CK3 and M9 rootstocks. The better result was shown by pruning of medium density
In modern Russia, there were not created key institutions of political and social development needed to involve young citizens in political and legal life, and very serious criticism is "the effectiveness of judicial reform" and the results of combating systemic corruption, without which it is difficult to count on the impact of the decrease in the level of political and legal nihilism among young people. The review of related problems and approaches to their solution are addressed in this article
In the article, the approaches to youth study as special social group are analyzed; social, demographic and subject-valuable measure of lamination of breeds are justified; stages of youth age are listed; necessity of development of the state youth policy is considered
In this article, we are talking about language mentality
of youth. The problem is multifaceted and allows the
researcher to see different aspects of the interaction of
language and mentality, and also their actions in unity.
Mentality of young people is largely determined by
social conditions, which is expressed in language
features. Language, in turn, has some formative
influence on the socialization process of the youth
mentality. Philosophers, psychologists, linguists,
historians examine various aspects of interaction of
mentality and language, relations between language
and thought, language and history, language and
national culture, language and learning, language and
humor, etc. In this article, exploring the mentality of
the youth system, we distinguish among them
language. The goal is to show features of youth
language mentality as a way of perceiving the world,
to determine levels (degrees) of functioning mentality
as a language picture of the world, to identify the
factors of formation of individual linguistic mentality
of the individual and the social environment
The role of youth′s self management institutions operated at bodies of legislative and executive power of Krasnodar region and municipalities of the region is presented in the article. The concrete forms of youth′s representation which we can see in Kuban′s practice are allocated
We have performed a mechanical activation of TiNi
powder; as a result, PN47T26TS27 powder after
mechanical activation is flat discs ranging in size
from 10 to 30 microns. We have developed a
composition technology "steel - material with shape
memory effect" by high-velocity oxygen-fuel
spraying of mechanically activated powder based on
TiNi. We have determined the optimal processing
parameters to ensure a nanostructured surface layer.
We have estimated the process parameters of highvelocity
oxygen-fuel spraying. The basic parameters
are: propane flow rate 60-85 l / min, that of oxygen
120-160 l / min, flow rate of powder and carrier gas
(argon), distance and angle of deposition, and
movement speed of the torch, the rotation speed of
the coated workpieces. We have carried out macroand
microanalysis of surface layers of Ti-Ni based
alloy, obtained on proven technology. We have
studied the effect of TiNi doping with a third
component Zr. The simulation allows us to predict
the possibility of using surface modification of
products with SME material TiNiZr under certain
conditions of temperature and to determine the
desired composition of the coating, which provides a
positive effect. We have made tests on steel 45 with
a surface-modified layer TiNiZr under dry friction
conditions, during which there is a significant
increase in temperature, we have confirmed the
effect of improving the wear resistance
Using zoonyms is one of the main ways of naming American football teams. Implicit qualitative features of the zoonym’s meaning motivate to choose a name of this or that animal. Zoonyms in the teams’ names are a result of self-estimation act. With the help of
zoonyms footballers try to present themselves as a strong, competitive and successful team
