The article deals with the methods of efficient sprinklers choice for farms of concrete irrigation zones on the basis of multi-dimensional statistics methods use
There was determined that the heat resistance of fruit and decorate plants depends not only on their morpho-biological peculiarities but on the specific of temperature stressor revealing in corresponding years. There were selected three types of influence of high air temperature on plants on plants during summer period and three components of heat resistance respectively. There were cited possible mechanisms of plant adaptation to overheat. There were cited diagnostic criteria of their heat resistance
Value of new linear sorts allocated by the method of analytical selection from sort Stepnaya 7 in increase of adaptability of winter soft wheat is discussed. The new linear sorts: Line 15, AMMA, Line 21, Line 11, Line 26, Line 29, Line 36, Line 37 revealed combination of stability to brown and yellow rusts. Productive varieties with high quality of grain: Magnificent, Line 12, Line 38 have shown stability to a brown rust and poorly affected by other mushroom diseases
The article presents the data of many years of research
on resilience, durability and natural renewability of
forest park plantations on sand and shell soils of the
Eastern Azov
27 introduced variety samples of rice from 8 countries
were studied by the complex of biological,
morphological, agronomic traits to select the most
valuable genotypes for including them into breeding
programs on development of cold tolerant rice
varieties. It was found that the studied introduced
varietal samples were characterized by variation in
duration which varied from 120 to 182 days. Variety
samples from Bhutan ATTEY, PARO DUMBJA
(White) had shown response to photoperiod and the
panicles didn’t appear in conditions of Krasnodar
region. During the study there were selected high
productive forms Obongbueo and Tinbubueo from S.
Korea with grain weight 81.67 g / vessel and 74.43 g /
vessel, respectively. According to results of research
there were selected five cold tolerant samples Tong
Jing 29 (China), Giza 178 (Egypt), Istigbol and
Mustagillik (Uzbekistan), ZAKHA (Bhutan),
evaluation result of which were on the same level with
those of standard check variety Kuban 3, as well as
those of samples with increased resistance IR83222-
F8-14 and IR83222-F8-156 (Philippines), PARO
DUMBJA (White) and THIMPHU DUMBJA
(Bhutan). As a result of research there were selected
three introduced rice variety samples Tong Jing 29
(China), Tinbubueo (S. Korea) and SR 30084-F8-156
(Philippines) which by duration, morphotype and
agronomic traits are considered as candidates for
further hybridization and breeding as sources of useful
traits and properties
The article contains the summarized information on
the activity of a farm having a sector of
“Agrotourism”. There was revealed the positive
dynamics of development of agricultural tourism in
the Krasnodar region, the extension of offered
services in this direction; there was set the obstacles
restraining the development of the present sector.
There were named the reserves to increase the
profitability: (domestic milk production and
participation in programs of state support
The article contains generalized information on the
activities of peasant farms in cultivation of turkey for
meat using outdoor technologies. The production is
cost-effective, although the rates of live weight gain
and the cost of feeding do not reach the requirements
for the cross. There are some reserves to improve the
profitability (introduction of floor cell technology,
optimization of feeding and participation in
government support programs)
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
After World War II, in 1946, our country understands
the problem - a terrible drought. To protect themselves
against such disasters in the future, on October 20th
,
1948, by the Council of Ministers of the USSR and the
Central Committee of the Central Committee of the
All-Union Communist Party of the Bolsheviks a
resolution "On the plan of shelterbelts, the introduction
of grass crop rotation, construction of ponds and
reservoirs to ensure high crop yields in the steppe and
forest-steppe regions of the European part of the USSR
" was adopted, later known as the "Great Plan for the
Transformation of Nature". During the years 1950-
1965 it was planned to create the next big state
protective forest strips from Saratov to Astrakhan on
both banks of the Volga River; - in the direction of
cities and towns: Penza - Ekaterinovka - Veshenskaya
- Kamensky, in watersheds of the rivers Khoper and
Medveditsa, Kalitva and Berezovaya; in the direction
of cities Kamyshin - Volgograd, in the watershed of
the rivers Volga and Ilovlya; in the direction of towns
Chapayevsk - Vladimirovka; in the direction of cities
Cherkessk - Elista - Volgograd; - in the direction of the
mountain Vishnevaya, Orenburg, Uralsk and the
Caspian Sea on the banks of the Ural River; in the
direction of cities: Voronezh - Rostov - on - Don; on
both banks of the Don River; on both banks of the
river Seversky Donets from the city of Belgorod to the
Don River. Strips were created in the steppe and forest
steppe areas. It was the first, in the history of
humankind, largest environmental program of impacts
on the climate of the huge territory, designed to protect
permanently fertile agricultural lands from harmful dry
winds, dust storms, lack of moisture and soil erosion.
We have studied the site of the State protective forest
strip "Cherkessk - Elista - Volgograd" located in the
"Kuban forest districts" of the Karachay-Cherkessia
Republic. In this area the analysis of taxation
indicators was made, the dynamics of change in the
stock of plantations connected with age was studied
The role of root and aftermath residues of basic field farm crops for retention and increase in organic matter content of the soil with fertilizing and fertilizer omitted is substantiated in the article. It is ascertained that the quantity of aftermath residues coming into the soil is 2,6-3,5 times less than that of natural vegetation while dry matter is removed with the main production and by-products 2,0-2,2 times more than is remained in the soil
