The article presents the data of 40-year-old variety-trial
cultivation of hybrid black poplar and balsamic sections,
as a result of which addressed issues of selection range
of appropriate varieties, their cultivation technology,
aspects of agrotechnology and protection against pests.
At the same time, it absorbed and non-forest land
reclamation funds, in particular sandy and shell, lowhumus,
floodplain soils. As a result, the five-year variety
trials found that under the conditions of the Eastern
Azov on humus shell rock underlain by low-mineralized
groundwater on accessible depth for roots (up to 150
cm), the most highly productive and are stable clones of
Euro-American poplar: Brabantika-175, Sanrau-59, a
Moshnyi-236 and 195 , Bahel, ZS-33 Vernirubens,
60001/1, Caroline-162. In terms of growth, they are
superior to the local Canadian poplar and other varieties
of poplars. Resistance to environmental and biological
factors of the environment most highly productive
species and varieties of poplars are much higher than the
low productivity. Culture of poplar planting might create
unrooted plants directly on the silvicultural area, which
reduces the cost of rooting plants at the nursery, their
digging and transportation and provides a high survival
rate. Culture of poplar are used for the afforestation of
poor sandy forest-steppe zone arrays, often introduced as
the main breed at shelterbelt afforestation
The article presents the indicators of the protective
afforestation of the Central black earth region, biometric
growth index, agricultural and environmental impact of
forest belts, efficiency of agroterritories
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
Early-ripening white cabbage has a special place
among the vegetables cultivated in Kuban region. It
opens the pipeline of vegetables from the open
ground and is supplied to other regions at a time
when shortage of vegetables of domestic production
is felt the most. Modern producer requirements to
domestic hybrids are the highest - product quality,
uniformity and productivity should not concede to
foreign analogues. Ways to improve the quality of
early ripening hybrids: development of lines based on
modern foreign hybrids, high uniformity of lines by
morphological and economic traits. Development of
male sterile lines and dihaploid lines in culture in
vitro can more successfully solve the problem of
quality of early ripening hybrids. The use of the
above methods and approaches helped develop series
of inbred lines - gene sources for complex agronomic
traits. On the vase of obtained lines promising earlyripening
hybrids were developed. One of the hybrids,
Ritsa F1, entered the State register of breeding
achievements. Advantages of the hybrid: earliness,
uniformity and high marketability of heads, high
productivity. According to results of contest trial new
hybrid Milana F1 is passed for State trial, this hybrid
has high productivity potential for growing in sale
cropping. Both hybrids were produced with the
participation of male sterile line Dt46f, resistant to
fusarium. High quality seeds of these hybrids were
produced in a greenhouse in direct crop for a wide
industrial and environmental testing
Numerous studies have found a different quality of the
buds along the length of the fruit arms, which expressed
various degrees establishing embryonic inflorescences in
the central buds. It is revealed that many of the grapes
have more fruit-bearing eyes formed on average (4-6
knots) and upper (7 to 10 knots) levels of fruit escape,
compared to the lower (1-3 nodes) layer. In connection
with the different quality of the buds along the length of
fruit vines should be used and different ways of cutting
them. It is necessary to consider the biological
characteristics of varieties, ways of doing and shaping
the bushes, the weather conditions of the area during the
growing season and relative calm. To receive annually a
stable high yield of grapes, we must first set the optimal
length of pruning fruit shoots and optimal load on the
Bush healthy eyes. This requires for each class on the
eve of trimming bushes to carry out the analysis of the
wintering holes along the length of the fruit shoots and
to identify the embryonic fruitfulness of Central buds,
i.e. to carry out the prediction of grape yield next year.
The article presents data on the formation of the
embryonic fruitfulness of Central buds of wintering buds
at the Taman group of grapes – Arcadia, Viorica,
Hibernal, Cabernet Sauvignon, Merlot, Moldova, Pinot
white, Riesling, Saperavi, Traminer pink, Tsimlyansky
black, Chardonnay. Found higher rates of embryonic
fruitfulness of Central buds buds in the studied grape
varieties - Chardonnay, Riesling, Viorica, Hibernal,
Merlot, Moldova, where the coefficients of fruiting
ranged from 1.40 m from Riesling to 1.69 from Merlot;
factor productivity of 1.58 from the Chardonnay to 1.77
from Merlo. The high percentage of fruitful buds from
80,8 from Cabernet Sauvignon to 95.6 in the cultivars
Merlot and Chardonnay. A higher percentage of eyes
with 2 embryonic buds in the cultivars Merlot and
Viorica who have this indicator amounted to, respectively: 75,6 and 70.6%. Forecasting a crop of
grapes next year to trim the bushes on the proposed
method will provide a full crop of grapes
One of the most destabilizing factors of crop production is weed infestation of crops. Despite annual herbicide treatment, weed infestation of crops of winter wheat remains high, with a predominance of annual dicotyledonous weed with a higher proportion of drug resistant on the basis of 2,4-D. We also notice increased range and density of perennial dicotyledonous weeds. New combinational herbicide called Cayenne, manufactured by LLC "Agro Expert group", which in its composition contains two active substances: thifensulfuron-methyl (500 g/l) and florasulam (170 g/l), highly inhibits both annual and perennial dicotyledonous weeds. According to the working program of the registrant's company we have tested Cayenne on crops of winter wheat in spring in the tillering phase and the formation of the second internode. It is shown that its use in doses of 0.025 and 0.035 kg/ha in mixture with 200 ml/ha of surfactant-Bit 90, W provides effective suppression of annual and perennial dicotyledonous weeds (90 – 100 %). The negative effect on the culture was not observed. At the same time, within 2-3 days after herbicide application we observed cessation of growth, chlorosis, dieback of growing points of weeds. Complete death was observed after 15 – 20 days
The effect of seeds shapes and sizes to field survival, plant stand, harvesting amount and structure of calendula crude drug were under investigation. Biological feature of calendula is heterogeneous seeds formation, when the same inflorescence forms seeds of various shapes and sizes. The following seeds fractions according to their shapes and sizes were used for sowing: uncinate shaped, crescent shaped as well as unseparated, including, except uncinate and crescent seeds, ring-form and scaphoid shaped seeds. It was discovered that maximum indices of laboratory, field survival of calendula seeds and plant stand were in conjunction with uncinate shaped seeds. Maximum crude drug harvest was in conjunction with the sowing seeds of uncinate shape, varied from years from 2.11 to 2.40 t/h; minimum- at unseparated seeds sowing, varied from years from 1.83 to 2.05 t/h. Crude drug extreme efficiency was determined in 1-3 gatherings by inflorescence weight gain and its quantity increase on the same plant. According to the size of elements of crude drug harvesting structure (inflorescence quantity and mass of the same plant, the same inflorescence mass) the variant of uncinate shaped seeds sowing had advantages
The accumulation of heavy metals was studied in different component parts of a White squash (skin and flesh, flesh, seed skin, seed kernel, peduncle). It is known that the basic source of feed for agricultural crops are mobile water soluble organic and mineral soil combinations which are polluted by heavy metals in different degrees. In the process of their migration they are able to accumulate in different parts of plants or to disperse. The mechanism of quantitative estimation of migration of heavy metals in direction of removal of mobile water soluble soil combinations to various parts of a White squash is developed by the author. The ranks of mobility of heavy metals are made from the most mobile manganese to the most indifferent iron. The model of estimation of mobility of the rest spectrum of heavy metals is chosen, namely: lead, cadmium, zinc, copper, nickel, cobalt in relation to manganese and iron. Basing on the position of a separate element in a mobile rank and its concentration it is possible to define the source of entering to a squash fruit. It may be water soluble soil combinations, irrigation water and atmospheric aerosols
The reaction of winter wheat cultivar ‘Antonina’ on the level of fertility and doses of fertilizers on crop productivity was studied. Investigations are carried out in multivariate 11 –course crop and grain-grass rotation stationary: factor ‘A’- the fertility of the soil; factor ‘B’ - fertilizer system; factor ‘C’ - the system of plants protection; factor ‘D’ - the main methods of soil tillage. Four models of soil fertility levels were studied in the experiment: А0 - initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of solid manure); А2 - high (double dose); at А3 - high (tripled) on three backgrounds of basic soil cultivation: nonmoldboard, recommended, moldboard with deep bursting and without the application of tillage (direct seeding and the natural rate of soil fertility). The soil is heavy leached black humus with humus content in the arable layer of 2.5% - 2.9%. On the basis of proven researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased and nitrogen - up to 140 kg per hectare. The increase in yield is due the rise of the quantity of grains per ear and weight of grain per ear
The impact of anthropogenic pollution on soil
phytotoxity and on triticale plants in Vladikavkaz
suburb was investigated in the work. The objects of
the study were sod-gley leached soils and different
varieties of triticale plants. The research was
conducted in 2010-2011 at the Department of Biology
of Gorsky State Agrarian University. The article gives
data on microelements content in soils and plants
within the range of influence of Vladikavkaz industrial
enterprises. There was a marked change of
miroelements’ mobility in soil and activity of their
penetration into plants during fertilization. The sort
characteristics of microelements’ accumulation in
vegetative mass of triticale were researched. The
conducted research is informative for soil and plant
condition monitoring in anthropogenically polluted
environment. The work indicates the increasing danger
of microelements (including heavy metals)
accumulation in soil and their inclusion in biological
cycle in concentration that is too toxic for plants,
animals and people during the usage of fertilizers,
especially their high doses. The most dangerous
among heavy metals are mercury, cadmium and lead.
We used MPC rate of excess to estimate the content of
these metals. The results of the research can be used in
soil and cereal plant condition monitoring and
diagnosis and in development of regional
environmental regulation
