The research purpose was estimate of the red oak
growing suitability in Mari El Republic. To achieve
this goal we investigated experienced 44-year-old red
oak plantation at the Botanical garden-Institute,
determined acorns morphological characteristics of red
and English oaks and seedlings grown from them. The
evaluation of red oak plantings identified excess of
average height and tree diameter in comparison with
English oak, but the sanitary condition of both oaks
forests was weakened due to the influence of the
complex of unfavorable factors. Morphological acorns
evaluation showed that the shape factor of acorns of
English oak is equal to 1.64, while the red oak is 1.1.
Biometrics parameters of red oak bareroote seedlings
in the field were higher than English oak bareroote
seedlings. In greenhouse biometric parameters of red oak container seedlings had not excess. According to
this research, red oak is recommended for use in
landscape construction in Mari El Republic
During the last century, in the biosphere occur expressed processes of soil degradation due to anthropogenic influence, which seriously change of top layer of soil. The agricultural landscape is allocated of noticeable accumulation of various wastes at expense of growing of food crops and grazing of farm animals, as well as due to mineral wastes generated in process production of building materials and fertilizers from natural raw. According to physical and chemical characteristics of wastes of plant origin and natural-raw wastes constitute a non-toxic highly dispersed connection with an admixture of different undecomposed organic and mineral substances. Specificity of physical state is determined there of high dispersion, which is represented by system particles of colloidal substances distributed in various environments. Colloids of natural-raw wastes are characterized by a low rate of diffusion; do not penetrate finely porous membrane of cell structures, different very nonequilibrium insolubility and specific chemical composition. For example, phosphogypsum is characterized by high concentration of sulfur and calcium, and trace amounts of entire table of D.I. Mendeleev. Organic wastes are made by variety of chemical compounds and high concentration of carbohydrates, proteins, fats and other organic substances
One of the limiting factors to obtain high yields of
grape plantations in Anapa-Taman subzones with good
quality is moisture. Grape plant adapts well to a
limited amount of moisture in the soil. The penetration
of roots deep into the soil horizons may reach 5-6
meters, provided with a moderate density of the soil
and the lack of limiting factors such as the presence of
ground water and limiting the content of toxic soluble
salts. In the course of mathematical data processing we
have established a trend of increasing average annual
rate of precipitation in the period from 1932 to 2015.
In the years when the amount of precipitation for the
year exceeds the average long-term performance, the
key amount of precipitation in the summer months in a
downpour and in a limited area. Average annual
amount of precipitation in the period from 1932 to
2015 was 519 mm, the minimum was recorded in 2002
(324 mm), the maximum - in 1981 (800 mm). Despite
the general trend of increasing average annual rainfall
over the years, moisture deficit is in the soil.
Accounting of moisture saving dynamics in the soil in
the 2015-2016's indicates the absence of moisture
reserves. Optimal soil moisture values were observed
only in May and June, and only half meter layer of
soil. In the phase of growth and ripening berries (July,
August, September) soil moisture content was much
lower than the permissible value, which is comparable
with the level of wilting point. For the stable-quality
grape raw materials it is necessary to pay more
attention to the water and the air regime of the soil
In order to reduce the impact of stress factors on the
body of pigs, new technologies and efficient
veterinary and preventive measures in breeding and
cultivation are being developed. The results of our
scientific and economic experiments found that the use
in daily diets of pregnant and lactating sows according
to our schemes of biological additives (to finish /
day.): Laktobifid (1 g), Immunobak (1 g), Provagen
(10 g ) Vetom 1.1 (50 mg / kg body weight), Bacell
(0.3% by weight of the feed) and Monosporin (10
mL), contributes to the improvement of their
reproductive qualities: for twins - on 2,2-12,2% by
krupnoplodnosti - by 8,0-10,7%, for milk - by 8,9-
36,5%, at the preservation of pigs - by 1,3-8,3%, by
weight of the nest 2 months of age - 22 , 9-38,9%
compared with the control. At weaning piglets from
sows experimental groups indicators of natural
resistance were significantly higher. The best
reproductive performance were observed in sows
treated with diet and probiotic supplements
Immunobak Bacell combined with Monosporin . The
results of these experiments revealed adaptogenic
properties of the studied additives, their ability to
mitigate the impacts of technological stresses,
reducing as a result of the cost of the products. Of
great practical importance is the ability to predict the
effectiveness of the use of additives which have antistress
effect, depending on the body weight of
animals, their age, frequency and duration of their
application before and after the impact of
technological stressors in the suckling period, the
periods of rearing and fattening up of live weight and
100 и 120 kg
Peach fruit is much demanded worldwide. The
success of its cultivation depends on the optimal
plant placement of all the huge biodiversity
considering the cultivar demands. The northern
boundary of the peach cultivation passes through the
Kiev-Kharkov-Rostov-on-Don, Maikop, Nalchik,
Grozny, Astrakhan (Witkowski, 2003). However,
because of extreme temperatures there are almost no
suitable areas for Peach crop cultivation in these
borderlands, in the Krasnodar and the Stavropol
regions. From the other hand, extreme temperatures
for peach cultivation in the humid Russian subtropics
were not observed. Spring frosts till -5 ° C were
observed in 2004, 2014. However, the cultivar
productivity in the region influenced by the duration
of low temperatures (7,2 ° C and below) that were
observed from December to March. The amount of
low temperatures for each cultivar was established
using the highest coefficient of yield determination,
depending on the temperature, amount of
precipitation and the "cooling unit." The yield of
peach cultivars is closely linked with the abovementioned
agro-climatic conditions during the
flowering period. Paired correlation coefficients of
yield with precipitation and with temperatures (for
most cultivars) were negative, and since they are
unregulated value, the flowering phase is crucial for
peach culture in the Russian subtropics
This article summarizes results of the research on the
assessment of soil erosion effectiveness of crops and
the rationale of the practical application of phytomeliorative
actions aimed at improving the erosion resistance
of slope lands. We have obtained values of the
resistance of soils to erosion under agricultural crops
and in terms of pure steam and calculated the indicator
of the efficiency of soil conservation crops. The tests
allowed differentiating the crops on well, poorly and
very poorly in protecting forest soils from erosion
Numerous studies have found a different quality of the
buds along the length of the fruit arms, which expressed
various degrees establishing embryonic inflorescences in
the central buds. It is revealed that many of the grapes
have more fruit-bearing eyes formed on average (4-6
knots) and upper (7 to 10 knots) levels of fruit escape,
compared to the lower (1-3 nodes) layer. In connection
with the different quality of the buds along the length of
fruit vines should be used and different ways of cutting
them. It is necessary to consider the biological
characteristics of varieties, ways of doing and shaping
the bushes, the weather conditions of the area during the
growing season and relative calm. To receive annually a
stable high yield of grapes, we must first set the optimal
length of pruning fruit shoots and optimal load on the
Bush healthy eyes. This requires for each class on the
eve of trimming bushes to carry out the analysis of the
wintering holes along the length of the fruit shoots and
to identify the embryonic fruitfulness of Central buds,
i.e. to carry out the prediction of grape yield next year.
The article presents data on the formation of the
embryonic fruitfulness of Central buds of wintering buds
at the Taman group of grapes – Arcadia, Viorica,
Hibernal, Cabernet Sauvignon, Merlot, Moldova, Pinot
white, Riesling, Saperavi, Traminer pink, Tsimlyansky
black, Chardonnay. Found higher rates of embryonic
fruitfulness of Central buds buds in the studied grape
varieties - Chardonnay, Riesling, Viorica, Hibernal,
Merlot, Moldova, where the coefficients of fruiting
ranged from 1.40 m from Riesling to 1.69 from Merlot;
factor productivity of 1.58 from the Chardonnay to 1.77
from Merlo. The high percentage of fruitful buds from
80,8 from Cabernet Sauvignon to 95.6 in the cultivars
Merlot and Chardonnay. A higher percentage of eyes
with 2 embryonic buds in the cultivars Merlot and
Viorica who have this indicator amounted to, respectively: 75,6 and 70.6%. Forecasting a crop of
grapes next year to trim the bushes on the proposed
method will provide a full crop of grapes
The contents of lead in soils are primarily determined by regional factors: the composition of parent rocks, relief, climate, vegetation. In recent years, these factors have increased the anthropogenic source of element. In order to assess its impact, requires knowledge of the natural, i.e., background lead levels, the so-called reference points, which can later be used to monitor changes occurring in the soil. Under background refers to the content of the element in soils at a great distance from the areas of receipt of contamination. Background content of lead in each type of soil depends mainly on composition of parent rocks. The correlation coefficient between the content of lead in parent rocks and soils, with the background contents is equal to 0,86±0,17 at p=0,95. For each soil type there are low variations in lead content due to the composition of parent rocks. Lead concentrations in the soils increased at the expense of its receipt from the atmosphere, irrigation water, drainage during mining, as a result of agricultural use, lead containing chemicals. Comparing the obtained results with existing currently permissible concentrations (APC, MPC) it is necessary to note that the lead content in leached chernozem soil after three rotations of the rotation may not cause any pathological changes or anomalies in the course of biological processes and lead to accumulation in the agricultural plants, and therefore may interfere with biological optimum
The article considers approaches to conducting longterm
observations, i.e. monitoring of the
immunological characteristics of varieties of winter
wheat. In our work, we use the following grading
system for the immunological characteristics of winter
wheat varieties for resistance to leaf rust in various
stages of ontogeny: evaluation of sustainability in the
seedlings in a phytotron, greenhouse complex;
evaluation sustainability in a field of artificial
infectious background; immunological evaluation
based on phytosanitary monitoring in different
ecological zones. In the initial stages, all the material is
pre-tested in the field of infectious hatchery. We have
performed an evaluation on the intensity of lesion and
the type of plant response to the introduction of the
pathogen. This approach allows getting rid of
susceptible genotypes for a year. To describe the
spread of rust, i.e., increase in population numbers we
have used two types of curves: J-shaped and S-shaped.
The article considers several winter wheat cultivars
differing in susceptibility to leaf rust. It is established,
that the increase in the population of brown rust occurs
in conditions with limited food resources and it is
described by the Ferxulsta function. Monitoring
studies allow developing models taking into account
the promotion of the parasite and its pressure on wheat
cenosis as well as allow building an expert system that
optimizes the protection of plants against leaf rust and
used to study the behavior of genotypes with different
immunological parameters when creating a model
class
The presented research is devoted to the development
of the import-substituting production technology of
the proteins dresser for food from local vegetable
resources, in particular, of lupine. Lupine seeds
contain about 40% of protein rich in all irreplaceable
amino acids. Protein of lupine noticeably differs from
protein of soy in inhibitors content, and namely,
proteases, that does not cause allergic reactions. The
main part of oil composition of oil of lupine is maid
up of linolenic, linoleic and olein acids. Use of lupine
seeds in production of complex raw structure
products will allow to increase the biological value of
a proteins component of a traditional type of raw
materials of phytogenesis and to reduce the available
deficit of protein. It is a will-know fact, that lupine is
added to the recipes of buns, fermented milk and
cottage cheese products, rich crackers and long
cookies. Technologists have recently received a
certain concentrate from lupine seeds of high
biological value, and a pastelike concentrate of lupine
which can be used as a filler in milk, meat, baking
and confectionery industries is being under development. The results of the research show that
seeds of lupine can be considered as one of the
perspective sources of white and competitive
ingredient for developing new recipes and
technologies of different types of multicomponent
food. It is necessary to continue the research on
creation of different types of food with use of lupine
seeds. Thus, the products received from lupine seeds
can be used as raw materials for improvement of
quality of food and as additives for creation of
compoundings of new types of foodstuff
