The article deals with theoretical and practical aspects of fighting weeds
In this work, the influence of 10 stimulators on occur-rence of roots in plants of green shanks of 14 types of stocks of fruit crops is shown. Types of preparations are allocated, at which qualitative root-stocks mate-rial for each investigated genotype in a hothouse with the mechanism forming a fog are received
The stem form pathology, which causes the limited life – durability and pre-mature death of the tree is described. The stem form pathologies as well as the percentage of their occurrences, depending on specific factory (age, stand degree, tree origin, land form), are reviewed
Steady in a complex seedless Athena sort is born in Greece by Panteley Zamanidi and Leonid Troshin in 2001 by crossing of Sidiritis and Cabernet-Sauvignon sorts. Under morphological and physiological characteristics it is close to the group of Convar. pontica subconvar balcanica Negr. varieties of pool of Black sea. Duration of productional period is 156-165 days. Growth of arms is strong. Degree of ripening of a rod is high. Productivity is high. Percent of fructiferous arms is 90. The average weight of clusters is 400. It differs with high winter hardiness, drought resistance and raised stability to mushroom illnesses in comparison with seedless Euroasian grapes. A blossom bud has green color with yellowy-brown tones. A top of young arm of green color with a weak wine-red border and very strong web-like fluff. Young arm is red from the back, green with a belly with an average web-like fluff. Adult leaf is symmetric. Leaf plate is average or big, green color, five bladed, it is divided weakly. Both parts of a local teeth form straight lines. The form of petiolar dredging is open. Length of footstalk is average. One arm usually has two inflorescences, on 4th and 6th knots. Inflorescences are formed both on the arms which have grown from replacing buds, and from the arms which have been developed from sleeping buds on a long-term wood. The flower is hermaphroditic. Custer is large, branchy, winged, average density. Berry of the average size, roundish, blue and black color. Skin is thin, strong. Pulp is juicy, with solanaceous taste. Sugar content is high. Rudiments of seeds are small. The sort is intended for consumption in a natural way and for manufacturing dry red wines of various categories
The article presents an analysis of the statistical data on use of barley in the world agriculture. The dynamics of changes in acreage under crop has been studied over the past decade in the global community. The structure of indicators in barley’s area was reduced and the main regions of production have been described. As the world as some countries barley productivity was studied. The article presents the data on world production of barley for lust four years. The structure of production of the main producing counties for 2014 is presented graphically. On the basis of the material revealed, more than half of the total harvest of barley in the world has been produced by three regions: The European Union, the Russian Federation and Canada. The article presents a comparative analysis in the above productivity of barley by the world leaders in the production of this crop. A direct influence of environmental factors on final grain yield has noted. Also the issue of national economic importance of culture has been revealed. We have noted the areas of the culture use such as food, brewing industry, as well as livestock (as it is known, barley is one of the most valuable forage crops)
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
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
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 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)
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
