In the conditions of middle valley of the Lena River on
the cryogenic, inundated, cespitose and chernozemic
soils different steppe communities differently react on
dietary regime. Herb-grass phytocenosis at organic
dietary regime is reformed in cereal phytocenosis with
the contents of cereals to 76% and bean types 19% of
dry basis with productivity to 20 centner of hectare of
dry basis. At the same time the efficiency of the
improved phytocenosis was on charge exchange
energy of 17,3 mega joule of hectare, feed units 1032
and a crude protein of 247 kilo of hectare. The whetgrasses
phytocenosis has provided productivity to
19,4 centner of hectare and the content of perevarimy
protein in 1 feed unit up to 118 gram. So the most
effective for the steppe meadows is using complex
fertilizer (humus of 20 tons of hectare + N60P60K60),
increasing the productivity twice with a high quality of
food
The article analyzes the experience of zoning of
territory of the Bryansk region on the main factors of
erosion to select the measures to combat it. The
Bryansk region in its present borders, mainly
representing the middle course of the Desna river, has
been considered safe in relation to erosion. The
existing zoning is based on the quantitative
characteristics of the processes of erosion that
primarily allowed us to assess the scale of their impact
on nature and the region's economy. The erosion
zoning was performed on the basis of the map of
erosion-prone land. As a result of study and analysis of
all natural factors of erosion and land of the region
under study the regularities of distribution of land
erosion and intensity of spring rainfall and soil erosion
are detected. Under the leadership of Filin V. I., a
survey of the ravines of the region was conducted and
made the scheme of erosion zoning, according to
which the region is divided into three areas. It is
noteworthy Horinas E. V. research. When divided into
areas it was taken into consideration the need for each
of them specific actions to combat the causes and
consequences of erosion in relation to the peculiarities
of the latter in each district. According to the intensity
of the erosion processes and physico-geographical
zoning of the Bryansk region and the nature of
agricultural land use, specialists of the Bryansk branch
of the Institute "Rosgiprozem" produced erosion
zoning of the territory of the region, which highlighted
seven erosion regions. From the variety of methods for
zoning, the most appropriate in our view are created,
based on the estimated small-scale (medium-scale)
maps of erosion of land, capable of performing the
function diagrams of erosion zoning
The dependence of the productivity of the Riesling
Rennel vineyards and the quality of table wine from it
under the conditions of the Anapa-Taman Winegrowing
Zone was studied. It is established that the
vineyards of the Riesling Rhine variety are planted
with the highest yield, planted according to the
scheme of 3.5x1 m. In this embodiment, at a density
planting shrubs 2857 pcs. / Ha, the yield of grapes was
the highest - 131.4 c / ha. Maximum accumulation of
sugars in the grapes observed in the variants with a
width of 2.5 m aisle highest extract content from
different wine stocks options with row spacing of 2.5
m where the amount of extractables amounted to 17.1
- 19.2 g / dm3
. The increase in the total concentration
of aromatic compounds of up to 540 mg / dm 3
helps
to improve the quality of white table wine, and further
growth of aromatics to 1090 mg / dm3
- it reduces the
organoleptic evaluation. High tasting marks (7.88-8.29
points) received wine materials from sites having a
spacing of 3.5 m. Thus, considering the quality of the
wine, the cost of planting material, laying and care of
vineyards, it is worth considering the 3.5x1 planting
scheme , 5 m more suitable for the production of
quality table wines in the Black Sea agroecological
zone of viticulture in the south of Russia
The ecological state of soil on the globe is unstable.
Intensification of agricultural production is
accompanied by negative trends in changes in soil
fertility. One of the most important indicators of soil
fertility is its structural state. With a long time
cultivation of grapes in one place, the physical
properties of the soil deteriorate. The purpose of our
research is to study the process of destruction of soil
structure during the cultivation of vineyards. The
object of research is the soils of plots of various
agricultural uses (vineyards, field crop rotation, forest
belts). The research methods used in the work are
route-field surveys, a laboratory study of the waterphysical
properties of the soil. The article presents the
data of the structural-aggregate composition of the soil
from plots of various agricultural uses. From the data
given, it can be seen that the soil occupied by the vine
plantations is characterized by a poor structure and low
structure of the arable horizon. The share of
agronomically valuable aggregates is 40.4%, the
structural coefficient is 0.68 units, while in the forest
belt this figure is 5.7 units. The increased mechanical
load on the soil during the cultivation of vineyards
leads to a deterioration in the physical properties of the
soil. Soil with low indicators of physical condition is
more susceptible to erosion processes, such as water
and wind erosion. Water erosion annually causes great
damage to agricultural lands throughout the world. The
article clearly demonstrates and scientifically
substantiated the negative effect of the system of soil
content of vineyards on the type of black steam. Also
proposed are ways to reduce the mechanical load on
the soil and prevent the development of degradation
processes in the soils of vineyards
In the conditions of the two-factor field experiment,
the influence of four methods of incorporating straw in
the soil on the rice yield was studied: plowing, one-,
two- and three-time discs and three ways of
"processing" the straw: embedding in the soil of the
chopped straw in its pure form, together with
compensating nitrogen fertilizer and inoculated stubble
biodestructor Stemix ® Niva. It is shown that the
lowest yield is formed when straw is plowed, while
surface tillage of soil by one-, two- and three-fold
discs significantly increases the grain yield in
comparison with the plow by 2.4, 4.2 and 5.2 c / ha,
respectively. Taking into account that the double
disking provided an almost twice increase in the yield
of the crop and the absence of statistically significant
differences with the triple disking; it is this method of
incorporating the straw that should be considered the
most expedient. The introduction of a compensating
nitrogen fertilizer ensured a reliable increase in yield
by 5.1 and 3.7 centners per hectare in comparison with
the variants with the introduction of straw in pure form
and treatment with biopreparation. Calculation of the
share of the influence of the factors studied on the rice
yield showed that the method for embedding straw
provides 29.9% of the variability of the trait under
study, the method of straw treatment is 36.7%, and the
residual dispersion accounts for 33.4%. Incorporation
of chopped rice straw in the soil together with
compensating nitrogen fertilizer in the amount of 1%
of the mass of straw, by double discing, ensured the
receipt of a conventionally net income of 6940 rubles /
ha, the rate of return - 70.4% and the cost recovery -
1.7 rubles / rub
Development of confectionery sunflower openpollinated
varieties (OP-varieties) is a prospect
direction in sunflower breeding. High price level for
confectionery sunflower seeds pushes forward the
breeding program. The aim of our work is to study
dependence of main valuable confectionery seed
characteristics from plant density and to identify
sunflower samples, which decrease seed size at
minimum level under high plant density. The study
was done at All-Russia Oil Crops Research Institute
(VNIIMK) named by V.S. Pustovoit (Krasnodar) in
2015 and 2016. Seeds of different biotypes of OP
sunflower variety called Dzhinn were used as a
material. Samples were sown with 2 replications.
Every plot had 1 row. The highest yield of OP variety
Dzhinn was obtain under plant density 60 000 plants
per ha. 1000-seeds weight decreased with increasing
plant density up to 60 000 plants per ha. Prospect for
future breeding samples were identified which not
decrease the level of valuable traits under higher plant
density
The results of comparative analysis of three white muscat grades of grapes Viorika, the Muscat de Yaloven and the Muscat onitskan according to the biological indicators of fructification, productivity, quality of berries, mechanical structure of bunches, suitability for manufacture of direct extraction juice and dry wines are depicted in the article. All studied grades differ by high percent of fruiting runaways and high factors of fruiting and fructification. The highest factors of fruiting and fructification of runaways are reflected at grade Viorika, and the lowest - at a grade the Muscat de Yaloven. Biological indicators of fructification of runaways according to the length of a fruit spear are high and rather levelled at all grades. That is why, depending on bushes forming, it is possible to apply short and average (6-7 buds) length of vine cutting. Biological indicators of fructification of runaways from angular buds and sleeping buds are high enough, that shows to good regenerative ability of studied grades. Grades Viorika and the Muscat de Yaloven are tall, and the Muscat onitskan is average height. Degree of ripening of runaways at grades Viorika and the Muscat onitskan is good, at a grade the Muscat de Yaloven - satisfactory. Productivity of grades Viorika, Muscat de Yaloven and the Muscat onitskan is 77,94; 81,52 and 72,72 centner/hectares, and efficiency of runaway - 199,5; 193 and 221,9 with a significant difference between grades on both indicators. The exit of a mash at grades was 77,5-79,4 %. According to the contents of solids, sugars and acids, grapes of all grades correspond to requirements for manufacture of high-quality direct extraction juice. From grapes of these grades, it is possible to produce high-quality direct extraction juice under the name of ampelographic and blended grades.
Sampling estimation of dry wines from grapes of these grades fluctuates from 7,6 to 7,8 points: 7,8 (Viorika), 7,7 (the Muscat onitskan), 7,6 (the Muscat de Yaloven)
The article identifies the value of livestock in the economy of the Bryansk region; we have also given the spatial-temporal analysis state of the industry and identified the key trends in its development over the past 25 years. This work considers the geography of industries and production of major livestock products
The article contains data on results of calving and blood tests of heifers moved from the Astrakhan region in the Temryuk district of the Krasnodar region in the condition of early pregnancy. According to the accompanying documents, cell blood count, hemoglobin and biochemical parameters were consistent with species and age normal. Calving took place without complications and did not require delivery; received 36 of 36 calves from cows. The quality of the calves found to be satisfactory. On the 45th day of service period, clinical signs of impaired health status were present in 2 animals, however biochemical markers of liver disease, inflammation, and anemia was identified in 7 heifers. In the context of work on creation of livestock combined milk and meat productivity of inseminated heifers and heifers of the Simmental breed the Simmental semen (25 cows) and Aberdeen Angus (34 cows) breeds. Fruitfully inseminated 55 out of 60 animals; indicator of severity of calving was 8 % for Simmental cows. Calves of Simmental breed and Simmental-Aberdeen Angus cross-breeds meet the requirements for live weight at birth and the exterior. Farming on the formation of herds of milk and meat direction of productivity are found to be effective
In this article, we present the results of the experiments on
the potential of productivity and accumulation of the root
mass of the Alfalfa and Brome-grass, on the content of the
main nourishment elements and the consolidation of gross
energy in the roots and agroenergetical effect of the
collected gross energy in the conditions of permafrost turf
soil of the Middle Lena valley. The maximum productivity
potential of beans and cereals grass mixture was reached
on the basis of the organic mineral nourishment regime:
the collected exchange energy – 21,3 GJ, feed units – 1568
and collected raw proteins – 428 kg per ha. Thus, the
content of digestible protein in beans and cereals grass
mixture agrophytocenoenosis was increased from 118 to
124 g, that exceeded a zootechnic norm (105 g). In general
the nitrogen contained in the total root mass of beans and
cereals grass mixture agrophytocenoenosis was up to 26,6
centner per hectare and movable phosphorus- up to 33,6 kg
per hectare that can serve as the source of nourishment for
sown herbs. The maximal stock of gross energy in roots
was got in beans and cereals grass mixture
agrophytocenoenosis at organic-mineral degrees (humus of
40 centner per hectare once in 4 years + of N120PK60
annually) up to 157,1 GJ/ha, while the accumulation of the
root mass reached 140,3 centner per hectare at average
annual rates of accumulation of dry substance up to 24,5
centner per hectare. The processes of formation,
decomposition and death of roots in the beans and cereals
grass mixture agrophytocenosis take place almost in a
balance state. Wherein the biological factor, as the
inclusion of the Yakut yellow variety of the Alfalfa in the
grass stand, plays a positive role
