Productivity of seeds of cereal crops essentially
depends on the quality of the seed grain, which is
being defined both by biological condition of seeds
and technologies and technical resources, which are
being used in, machine processing of seed heap. In this
connection, different injuries of weevils which are
occurred while mechanical and thermomechanical
influences from tools of machines and aggregates have
got vital importance. Apart from the breaches of
integrity of the weevil’s cover there are also exist
traumatizing changes of its inside structures which are
frequently covered with casings and do not being
viewed with visual inspection. Conditions of inside
structures of weevils were researched with
radiographic method and also were defined possible
types of traumatizing changes which depend on
mechanical and thermomechanical influences, which
were eliminated in universal classification of injures
among the inside structures of seeds of agricultural
cultures. Also, wу have analyzed the influence of
chosen types of injuries on seeds’ sowing qualities and
found that all injures of weevils essentially and
differentially influenced the sowing and fruitful
qualities and should be considered while choosing the
technological schemes of preparation, working tools
and while tuning the aggregates’ regime of work
attached to the machine processing of grain and seed
heap
The increasing consumption of forest resources causes
a greater anthropogenic impact on forest ecosystems
and leads to a negative impact on both biodiversity and
the environment as a whole. In this article, the
sustainability of forest phytocenosises of southeast of
Western Siberia is assessed using the example of
Tomsk region. The analysis of the status and dynamics
of the forests of Tomsk region has been assessed. The
main factors negatively affecting the biodiversity of
forests of Tomsk region were analyzed. The forests
cover extensive areas; therefore, the studies were
carried out based on the data from the State Forestry
Register of the Russian Federation for the period from
2008 to 2015. According to the results of the study, the
sustainability of forest phytocenosises has increased
significantly in recent years, which can be explained
by its strengthened ability to maintain the current state
under the influence of external factors. This work
considers such causes of damage and death of forest
plantations as pests, forest diseases, unfavorable soil
and climate impacts, forest fires, as these are the main
and most massive phenomena that cause the greatest
damage to forest. It is possible to see the dynamics of
damage and death of forest plantations on the figures
presented in the article
The article considers the accelerated reprocessing
technology for recycling pig manure into organic
fertilizer. Today, closely relevant is the matter of
environmentally friendly technologies for cattle
manure utilization. Export of wastes in its pure form to
agricultural land cannot be applied, because disease
causing and chemical compound penetrated the soil,
entered the groundwater and contaminated many water
sources. Experiments for the accelerated reprocessing
of the pig manure into organic fertilizer were
conducted on the basis of PCF No. 2 of the APC
"Maryanskaya" in the Krasnoarmeisky district. With
the aim of eliminating the filtering of pollutants in soil
and groundwater, the experiment was performed in a
concreted area, located within a farm. For the test, we
used pig manure of animals, whose age was 2-8
months. The total weight of used manure was 40 t. The
accumulation of manure was carried out in containers,
containing 4 tons; the total time for the accumulation
of necessary amount of manure for 2 months.
Comparing the quality of compost obtained by the
proposed technology recommended for industrial
applications, control, we found differences in the
chemical and biological properties. Overall, the
conducted experiment has allowed to establish that the
best option, given the speed of the flow of chemical
and biological processes, demands environmental
protection, is composting manure with straw, adding a
biological product "Tamir" at the rate of 0.5 l/t. The
Obtained results are comparable with data of previous
years and indicate the possibility of reducing the
quantity of a biological product from 1 to 0.5 l/t of
waste without reducing the efficiency of the process of
accelerated decomposition of nitrogenous organic
compounds
The fattening of Holstein cattle for more than 90 % provides the beef cattle division of the firm «Agrocomplex» based in the village of Vyselki, the Krasnodar region. The share of the Aberdeen Angus breed is 6.3 % and Charolais at 0.6 %. The reason for insufficient supply with fattening complex of Charolais cattle is a high indicator of severe parturition, postpartum complications, and reduced productive longevity of cows of breeding herds of these breeds. In a "Livestock complex" bulls of breeds of Holstein, Charolais and Aberdeen Angus reach the required values of live weight for the established standards of the breeding time. Charolais have the best indicators of absolute and relative weight gain and the shortest feeding season. The profitability of cattle fattening in CJSC company "Agrocomplex" is low, but the efficiency of the industry is ensured by the presence of its own processing plants. To improve the profitability of beef production it is required to increase the proportion of specialized breeds for meat productivity; to generate the most uniform by age and live weight of the group; identify the cause of the high rate of culling of Charolais cows for postpartum complications and take action to address them
We have selected a group of test animals and formed a
set of techniques for the research. The article gives an
evaluation of fattening qualities (precocity, average
daily gain, feed consumption per 1 kg of gain) of
purebred and crossbred pigs. We present the dynamics
of body weight and body length for the experimental
pigs, productive qualities, the thickness of back fat of
experimental animals to achieve the 100 and 130 kg of
live weight
The article contains complex research results dedicated
of reproduction the cattle of the animal breeding
industry in the agricultural holding called “Kuban”.
Key indicators characterizing reproductive function at
cows were set; they were estimated in terms of the
plans of the economy in the milk cattle breeding
industry. The reduced values of the birth-rate of calves
were revealed on 100 cows and in the term of the
production use of cows, their main reasons were set.
The performed calculations prove the possibility of
increasing the profitability of milk production
The reaction of winter wheat of Krasnodar
Agricultural Research Institute selection that is
included in the State Register of selection
achievements in the Russian Federation, on the
predecessor, the sowing time and the level of mineral
nutrition in 2008 - 2010 was studied in
"Severokubanskaya agricultural experimental station"
P.P. Lukyanenko Krasnodar Agricultural Research
Institute, located in the northern area of the region.
The objects of research were cultivars ‘Bezostaya 1’,
taken as a standard, ‘Tanya’, ‘Grom’, ‘Sila’, ‘Ligue 1’,
‘Irishka’ and ‘Yumpa’, with a specific weight of
strong wheat (excluding the cultivar ‘Bezostaya 1’) -
57.1%, essential - 28.6%, weak - 14 3%. The
predecessors are winter wheat, sunflower, white
mustard. Seed dates: the 20th of September (optimal
for determining the originator of the cultivar) the 1st
and 10th of October. The background of mineral
nutrition is N0P0K0, N60P30K30 and N120-160P90K60. The
soil is an ordinary powerful heavy-loam chernozem
with humus content in the soil layer 0 - 30 cm 3.95 -
4.00%, of mineral nitrogen - 8.3 - 10.7 mg / kg of soil,
of mobile phosphates - 22.4 - 26 6 mg / kg of soil, of
exchangeable potassium - 330 - 360 mg / kg of soil.
Weather conditions during the research were
extremely contrasting, both by the precipitation and by
the temperature conditions. Based on these studies, it
was found that five or six cultivars of this crop that
differ in biological and economic features, the reaction
on the predecessor, soil fertility and sowing terms as
well as adapted to the specific soil and climatic
conditions should be used to obtain consistently high
yields of winter wheat. Well-chosen cultivars, predecessors and sowing terms predecessors allow
without additional cost on the unfertilized background
to increase the yield on 0.20 - 0.79 t / ha. Together
with the growth of yield, the technological quality of
grain is improved: protein content by 0.5 - 2.4%, fibrin
content - 1.7 - 7.6%. The principle of mosaic use of
cultivars with specific predominance of strong wheat
is 57.1%, essential - 28.6%, weak - 14.3%, it allows to
produce the grain when you apply the minimum dose
of 12.5% protein content, 20.9% of fibrin content.
When using N90P60K60 respectively 13.3 and 23.6% at
a dose N120-150P90K60 - 14.4 and 26.8% with an average
of 13.5 - 24.0%
The provisions to improve the efficiency of vineyards
are the selection of varieties different by ripening,
adapted to local conditions, as well as the use of a new
generation of fertilizers. According to phenological
observations and actual production period, the varieties
of table grapes are divided into groups by ripeness –
early and middle. According to the yield, there were
emphasized the following varieties: in the early group
– Cardinal (11,3 t/ha), Vostorg (Delight) (11,2 t/ha),
Bogatyrskiy (10,9 t/ha); in the middle ripening group -
Kishmish luchistyj (11,2 t/ha), Moldova (11,2 t/ha),
with large clusters (266-453 g) and berries (3,2-7,0 g),
a berries’ crush resistance was from average 850 g to
high up to 1528 g, berries’ strength of attachment to
fruitstems was high – 259 and solid – 666 g. It was
observed the positive benefit of foliar application of a
new generation of micro fertilizers. In the phase of
ripening of berries the total length of shoots of
fertilized variants was above the control variant for the
variety Ranniy Magaracha on 2,6-13,4%, for the
Karaburnu on 2,5-13,9%. Maturing shoots in this
phase was on the variety Ranniy Magaracha – 76,5-
92,4% (control variant – 74,6%), while on the
Karaburnu variety – 72,8-83,1% (control variant –
70,9%). Fertilizers contributed to the increase of leaf
area on the Ranniy Magaracha variety on 3,9-15,9
thousand sq.m/ha (control variant – 20,0 thousand
sq.m/ha), on the variety Karaburnu on 3,4-13,1
thousand sq.m/ha (control variant – 22,8 thousand
sq.m/ha). The yielding capacity on the fertilized
variants have increased by 7,1-23,0% depending on the
variety. The maximum yielding capacity was obtained
when using compound nanotechnological fertilizer
Nagro on the variety Ranniy Magaracha – 13,4 t/ha
and on the variety Karaburnu – 15,5 t/ha
In the soils of rice fields, eluvial gley processes
develop, which are manifested in redistribution of silty
particles along the profile, water-soluble humus,
mobile compounds of iron and phosphorus. Most
intensively, these processes are developed in meadowbog
soils, confined to closed depressions of the plains
plain. Meadow-black soils lying on elevated relief
elements have more favorable physical, physicochemical
and oxidation-reduction properties for
cultivating rice and accompanying crops in crop
rotation. The highest yield of rice is formed on high
checks and higher at 12,4 c/ha than on low ones
High growth-rate of plantlet is the integral index of
intensity of physiological processes at rice and other
cultures. 20 typical plantlets from each of two
variants were studded (in the distilled water in
thermostat at a temperature 29° C) by:
length of embryonic root and coleoptile. Comparative
analysis of trait characterizing the growth rates of rice
varieties showed reliable advantage of Russian ones
above the Italian and Chinese. Local varieties,
regionalized until the year 2000, exceed new ones on
this trait. Highest growth rates were characterized by
medium grain samples. The white grain and red grain
varieties are excelled other groups on the height of
plantlet. Analysis rates of height of plantlets in the
distinguished groups showed the necessity of
prosecution of improvement of the above enumerated
signs at the varieties of late term of ripening, long
grain, with Waxy gene, colored grain. We recommend
to sow this type of varieties on fields with good
leveling, because of low speed of growth
