The behavior, interior and milk yield of the mature Black-and-White cows with various productivity levels, as well as etology of the replacement heifers are researched. The superiority of the high milk yielding cows for the lying duration and eating feed and water is revealed. Reduced variability of vital behavioral actions of animals is found. In addition, high yielding cows has been lower variability in all feeding acts. It was noted that high yielding animals exceeded equal age cows by the level of most interior factors. The differences were significant on the content of hemoglobin, vitamin E, and especially on the content of iron. Positive correlations between some interior design indicators is found. The analysis of lifetime productivity during our research found that high milk yielding cows had highest yields on the first lactation and kept the same level in the next lactations with insignificant variations. The lower productivity animals reached maximal yields on the third lactation with the followed downward trend. Differences between groups in lifetime productivity during research amounted to 16 992 kg. The significant superiority of the heifers with high grown intensity above equal age animals for the duration of feed and water eating, physiological functions and lying. The analysis of variation coefficient is confirmed the observed regularities.
The studies revealed that the application of spirits as a
strength agent of 91.0 - 96.6% in special wines
contained more vitamin-like substances than wine,
alcoholized with double-distilled water with 75%
alcohol concentration. The highest marks for tasting
wines were given to the options made with the use of
rectified grain origin alcohol as an agent of alcohol.
Application of double-distilled water wine leads to
accumulation of unnecessarily high undesirable
groups of compounds such as methanol and fusel oil,
thereby reducing the quality of the wine. Organoleptic
parameters were the best for selection of wines from
Anapa ZOSViV - Dionysus and Krasnostop EPA, as
well as - Cabernet Sauvignon. We can conclude that
for the production of high-quality red dessert wines
we need, along with the classic varieties, wider use of
new autochthonous varieties using alcohol agents of
rectified grain origin
According to the results of anatomical researches is determined, that under three sides spring punning of roots simultaneous annual applying of regalis number of grown closed (fruit) buds increase about 22–26 % during the first year, but then influence becomes weak and about the fifth year it needs the second (repeated) pruning of roots. Under two-sides pruning of roots a little decrease of size (caliber) is noticed in such sorts of apples as Gala and Golden Delicious
The article presents the results of the control slaughter of purebred and crossbred lambs. It was found that the index of compactness and the main killer performance superiority had two or three breed lambs obtained from crosses involving sheep southern meat breed. The experimental animals were taken measurements of carcasses, which give a fairly complete and objective view of the differences in the length of the torso, hips, mascara and hip girth. There are specific differences in the yield of the most valuable cuts of the first grade the rams depending on the origin. The superiority of crossbred calves over the control for this indicator amounted to 16.4 and 33.4%. The chemical composition of the meat fine-wool lambs contained more moisture and less fat and less calories than meat crossbred animals. Increasing the hybrids values of the protein quality index indicates an increase in meat share of muscle proteins and the reduction of connective tissue, and consequently, improving the quality of the raw meat. Animals obtained by crossing, have wide and deep body, well-developed muscles of the thighs, the best quality characteristics of meat productivity
Increasing the yield of crops is a global challenge substantiated by the scientists from all over the world. To achieve this goal, there are various ways, one of which is the ozonation of seeds before sowing. This method inhibits harmful microflora, which could be formed on the seed during the period of storage, and excites the chemical processes within the seed that can accelerate the process of growth. But despite the positive effect of ozone-air mixture of seeds and a variety of conducting research there is still no reliable data on the technological parameters of ozone effects on seed crops (e.g., corn). In this regard, we have conducted experimental studies to determine the effective parameters of the ozonation of corn seeds, such as the concentration of ozone in the ozone-air mixture, exposure time and binning after treatment. The influence of these parameters was assessed by changes in growth performance of seed, such as germination, germination and growth of strength. Just at the end of the pilot study we carried out a statistical analysis of the data, which allowed us to estimate the degree of influence of each independent parameter (ozone concentration, exposure time, binning after treatment) for each dependent parameter (germination energy, germination, growth force). The data obtained is presented in the article
The article is devoted to the study of growth peculiarities of summer potato on floodplain lands of Southern Russia. High and stable yields in big farms are possible using substantiated planting time of potato which depends on specific soil – climatic conditions of the area as well as potato cultivation technology elements improvement under irrigation. The latter will provide in turn water and power resources economy. The results of field research to determine planting time allow defining the most favorable conditions for potato cultivation in the given soil-climatic zone. The analysis of data obtained on differential irrigation regimes gives a possibility to determine common regularities of irrigation standards impact on potato growth efficiency. The regime proposed is in conformity with the concept of ecological land reclamation and takes into account a moderate anthropogenic impact on landscape processes under a permissible level of summer potato productivity decrease. Therefore proposed optimal time of summer planting and rational irrigation regime will increase industrial efficiency of potato production and provide environmental safety of irrigation on floodplain lands of South Russia while allowing to economize water and power resources
Sorghum is cultivated in many countries of the world
on around 50 ml hectares. The main producers of
sorghum are India, Nigeria, Sudan and the USA.
Sorghum comes from equatorial Africa. India and
China are the secondary places of origin and formation.
The USA achieved great success in breeding, seedgrowing
and agro technologies of grain sorghum. In the
country sorghum occupies 14.4% of the world amount
of sowing areas; the gross yield is 40%. Sorghum
breeding on Don was started by E.S. Yakushevsky in
1938. In 1963 after a long break the work was restarted
at the Zernograd Breeding Station headed by Ya.I.
Issakov. At present the amount of sowing areas for
sorghum is constantly increasing in RF (220.3 thousand
ha in 2015). It occurs due to aridity of climate and more
frequent use of the crop as insurance. Besides, the
development of white kernel varieties gave an
opportunity to use sorghum for starch and spirit. There
are 221 varieties and hybrids of sorghum registered in
the State List. The main directions of breeding work
with grain sorghum are early maturity, suitability for
mechanical harvesting, productivity and grain quality.
The ARRIGC developed the white kernel early
maturing varieties ‘Velikan’, ‘Zernogradskoe 88’,
‘Ataman’ without necessity to be dried after harvesting,
with productivity of 8 t/ha. The main directions of breeding work with sweet sorghum are early maturity,
high intensity of initial growth, low height, resistance to
lodging, high productivity and quality of green chop.
The ARRIGC developed the varieties for fodder use
(‘Listvenit’), for spirit and treacle (‘Debyut’ and
‘Zernogradsky Yantar’). Sorghum due to origin and
varietal diversity even in dry and hot parts of the world
allow obtaining stable, high yields of grain and green
chop. This makes sorghum the leading grain-forage and
food crop
In the technology of cultivation of sugar beet the significant role is allocated for system of fertilizer. The research problem included studying of influence of various norms and combinations of mineral fertilizers on productivity and quality of this culture. In 2012-14 the stationary field experiment with sugar beet of a grade of "Nero" on an experienced field of department of agrochemistry in educational economy "Kuban" was put and made. Studying of the nutritious mode of the soil is one of the most important questions of determination of effectiveness of fertilizers. Researches showed that the application of double doses of nitrogenous, phosphoric and potash fertilizers, and also the complete fertilizer in double and threefold dose on the chernozem lixivious, has essential positive impact on the maintenance of like elements of a mineral delivery, providing the favorable food mode during body height and cultural development. Fertilizers promoted more intensive intake of nitrogen, phosphorus and potassium in plants of sugar beet. The maximal maintenance of these elements is observed in a phase of clamping of rows. In experience the good harvest of sugar beet was received. Average productivity made about 450 c he (the increase makes ot13,6% to 77,4%). The maximal productivity of root crops is received at importation of N80P80K80 and N120P120K120 also made 620,3 and 633,3 c/he. Our researches showed that sugar content of root crops by options of experience fluctuated from 14,0 to 18,7%. The best results are received in options with importation of N80P80K80 - in these options sugar content made 18,7%.Thus, optimum conditions for sugar beet are created at importation of the complete mineral fertilizer at the rate of N80P80K80
This article discusses the results of the study to determine the impact of different primary tillage and herbicide against weeds in winter wheat agrocenosis. The task of the research was to determine the impact of primary tillage (moldboard plowing and surface treatment) factor A and herbicide (Lancelot) factor B on the agro-physical and agrochemical soil properties. It has been established that the content of productive moisture during the growing period of winter wheat in 0-100 cm of soil layer didn’t depend on the method of tillage. Introduction of herbicide Lancelot boosted the moisture reserves in soil compared to the control type, in the herbicide-free type the weeds absorb the large amounts of moisture. Surface soil treatment did not have negative effects on soil agro-physical properties and its structure in comparison with moldboard plowing. Number of agronomically valuable aggregates on moldboard plowing is 85.2 - 87.5%, on surface one is - 86.2 87.5%. Density of composition and waterproof aggregates under surface treatment didn’t defer to tillage. Accumulation of wet and dry mass by weeds regardless to the way of soil tillage declined to a minimum when introducing the herbicide Lancelot. The high yield of winter wheat was obtained on this type. Mathematical processing results have shown that due to factor A (main soil tillage) to moldboard plowing the average productivity is 57.5 kg/ha, on surface one is 56.0 kg/ha, i.e. the difference between treatments is 1.5 t/ha (with NSR05 on factor - 2.9 t/ha) is insignificant. To factor B (herbicides) on control the productivity is 54.5 kg/ha, introduction of Lancelot increased the productivity to 59.5 t/ha, i.e. the increase was 5.5 kg/ha at NSR05-by the factor B-2.9 t/ha, i.e. is significant. Thus, the present soil treatments had no effect on yield of winter wheat in ordinary black soil. The use of herbicide Lancelot has produced the harvest increase in 0.5 t/ha on average for 2 years
