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
An analysis of the state of contamination of rice crops
with red-grained forms was carried out, as well as
impurity was found both in the seed material and in
the soil. It was shown that there is a need to switch to
non-weeding seed growing technology when
conducting elite and reproductive seed production.
Various variants of soil cultivation in combating the
red rice forms are considered, both in the main and in
the pre-sowing treatment. It has been found that after
harvesting rice on heavily foul areas, it is better to
burn straw, and not to carry out autumn tillage of the
soil, the seeds of red-grained forms die mostly when
wintering on the soil surface. The most effective
method of soil cultivation for controlling of red rice
forms in seed crops has been identified, in which the
yield is increased, and the contamination of crops and
the resulting rice grain is significantly reduced. The
work carried out will allow reducing manual labor
costs in the production of seeds, improving their
quality and assortment, speed up variety changing and
variety updating
Urban trees can provide multiple environmental
benefits. The study of the state of the street tree and
shrubby vegetation from the analysis of inventory data
and environmental conditions is purpose the article.
The structure of 11 types of street roadside vegetation,
which determines about 93% of the greenery
composition of the city of Ekaterinburg is considered.
The structure of the examined tree-shrub vegetation
and all vegetation, which is part of the greening of
Ekaterinburg, is compared. For each tree (shrub) was
measured: species, number of stems, diameter of stem
at 1,3 m, tree height, height to base of live crown,
crown width, percent of branch dieback in crown,
percent of canopy volume devoid of leaves, number of
sides of the tree receiving sunlight from above,
distance and direction to building, distance to road. As
a result, homogeneity of illumination of various plant
species is received. Ash ordinary has the largest of all
plants values of the percent of the missing crown
(61.3%) and closest distance to the road. The effect on
the plants (by average distance) of urban buildings (7-
30 meters) and the proximity of the roadway (3-7
meters) was observed
The study of the productive qualities of crossbred
offspring from different breeding combinations and
identifying the most effective ones providing the
maximum increase in the production of high quality
lamb while reducing its cost is an important problem
and is essential for further development of methods of
creating a new type of precocious meat and wool
sheep. In the Rostov region in the result of the
establishment of populations of meat-wool sheep there
are several groups of animals with different
characteristics and hereditary inclinations. As the base
of the work there is a method of mating and breeding
of sheep of the desired type. The article presents the
results of one of the fragments of a large complex
work in which the possibility of using three-pedigree
hybrids, created with the involvement of potential
salskaya, edilbaevskaya and intense meat-wool breed,
which is severokavkazskaya, to improve productive
quality in the breeding of sheep. We have evaluated
productivity and biological features of hybrids and
proved the economic efficiency of their use in the
production of mutton. We have given the results of the
control slaughter and assessment of qualitative
indicators of the meat of young sheep. The set of
indicators characterizing meat productivity and meat
quality revealed that the superiority of the studied
indicators remained for two - and three-bred cross
cattle. Hybrids have a higher rate of growth and
quality parameters of meat productivity. These options
are simple and complex industrial crossing are
promising and can be implemented and used on the
farms of the zone of breeding Merino sheep. Thus, the
use of crossbreeding gives an opportunity to convert a
flock of sheep in the desired direction quickly. At the
same time, three-pedigree hybrids better combine the
valuable qualities of the used species
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
The steady development of modern pig farming
dictates the need for new priorities, opportunities and
requirements, such as reducing harmful environmental
impacts, more efficient use of resources, and provision
of comfortable conditions for the pig housing. The
creation of an appropriate ITS BAT in the branch will
optimize the activity of agricultural pig breeding
enterprises due to the transition to performance of
requirements based on BAT technological parameters,
to solve the problem of energy efficiency, import
substitution and increase of competitiveness. Their
integration will have an effect not only on improving
the ecological state of the environment, but also on the
economy of agricultural enterprises providing a new
approach to agricultural activity
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 breeding programs, evaluation of initial material is
made on all the stages of developing the variety. Great
difficulties for the breeding process are made by
absence of modern mechanisms for storing, retrieving,
manipulating the relevant data, and using the
information previously obtained for use in solving the
set breeding task. In order to organize the management
of breeding process for development of high-quality
rice varieties, based on the urgency of problem of
intellectual analysis of data, the Database "Rice
Quality" was designed as a set of structured data - the
rice quality characteristics identified in the stages of
the process of developing variety belonging to the
"Rice". In the domain model, the infologic model, a set
of parameters for evaluating rice quality in terms of
out-of-program components is defined. The program is
written in the Microsoft Access database environment
using built-in query building tools, forms, reports. The
structure of the developed tables includes static and
refreshed directories in which the necessary
information is stored, the tables are combined into
one-to-many relationships, while ensuring data
integrity, cascading updates and deletion of fields
In the article, long-term data (2007-2015) of biometric parameters of an elevated part of plants are provided. Assessment of prospects of five introduced botanical species of juniper is carried out and recommendations about their use in landscaping are made. From 25 studied grades of junipers of types: Cossack, Sredniy, Virginia, Horizontal and Scaly we have established very perspective, perspective and a little perspective for gardening in the conditions of a foothill zone of the Krasnodar region
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)
