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 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
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
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
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
Technological methods of rice cultivation in Rostov region are considered in the article. Broadcast sowing method with rolling down the soil, application of op-timum fertilizer doses before blossoming, water schedule for weed control are recommended. Low rice percentage crop rotation for farms with unsatisfactory financial position and minimum technical equipment are suggested
The article gives data on the importance of mikro-fundi in the Central part of the Caucasus, causing fungi of leaves and ear
The article presents the results of studies on the species composition of fungi isolated from seedlings of grapes affected by vascular necrosis
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
We attempt to combine professional agronomic knowledge with familiarity with graphic art presented in the form of a poster in the paper. The term "poster" is considered a large loose-leaf edition, combines visual and typographic elements and execute graphic communications. The main idea of the poster is to convey the information to the reader quickly and accurately. In the study of the material we have formed complex scientific and educational resources on the history of agricultural science, including the history of the popularization of agronomic knowledge. In our work, the poster is treated as an object of analysis, as the material of social and cultural analysis and as a tool to gather information on the development of agronomic knowledge through their visualization. In the course "History and methodology of scientific agronomy" one of the competencies of students is familiarity with the methodology popularization of agronomic knowledge, understanding of what is happening. In this regard, an attempt was made to consider the Soviet poster as a source of information on the development of scientific agriculture in the period from 1917 to 1980. The aim was to analyze the main events of this period, elements of the technology of agricultural production, species and varietal diversity of crops, as well as various events in the agricultural sector. The article considers four basic types of posters: promotional, political, instructional, scientific and educational. Each of these types of posters performs its function. The poster covered all stages of agrarian sector of the country, was a historical reflection of the Soviet period and always remained mobile, online and popular art form. Today, his role is small, because it has changed the ways of presenting information. However, its historical role unchanged, he has served as the Foundation of the modern advertising industry, including agronomic knowledge
