The article discusses the current state of greening cities on the example of Volzhskiy. The story of greening plantation and measures to optimize the situation are reviewed
CULTIVATION OF VEGETABLE PEAS OF VARIOUS TERM OF CROPS ON THE IRRIGATED SOILS OF THE SOUTH OF RUSSIA
The efficiency, the vegetative period, duration of cleaning of grades of vegetable peas of various term of crops on the irrigated soils of the South of Russia are resulted in the article
In the course of research the impact of polymeric pellicle-forming growth regulators (PGR) on the growth and development of rice plants while cultivated in conditions of salinity has been studied. It was ascertained that preseeding PGR treatment of seeds at the rate of 10 liters of solution for 1 (one) ton of seeds boosts germination energy, germinating ability of seeds, sprouts, length gets extended and weight enlarged. PGR lead to increase of electrochemical gradient on the membranes of chloroplasts, tilacoids and acceleration of electrons transport between I and II photo systems. PGR diminish toxicity of salinity which is fixed in parameters measured in experiments that are close to the control values. PGR application improves parameters of the structure of rice crop cultivated in conditions of salinity.
The results of investigation of gene flow from herbicides resistant cultivated rice to weedy red rice are represented in the review. Ecological risk of introduction transgenic rice varieties is discussed
Progress of breeding for resistance to diseases, pests
and low temperatures is provided by cross-species
hybridization. Institute of Vine and Wine "Magarach"
is one of the leading centers of selection of grapes in
the world. The breeding program of deducing grapes at
the institute is based on the study and attracting the
world's gene pool, including and industrial of the
Russian Federation assortment of grapes. Analysis
assortment shows that the share of productive, highquality
varieties with group resistance to diseases,
pests and extreme environmental factors is very
small. The main method of selection of grapes of a
new generation who have genetically determined traits
earliness, resistance to biotic and abiotic factors is
crossing complex interspecific hybrids and forms of
their involvement with each other and with the forms
of species Vitis vinifera, belonging to different ecogeographical
groups, saturating crossing between
hybrid forms with complex features, the appropriate
selection of reference. For vigorous offspring is most
effective as a parent to use a local variety of forms of
Crohn and father - interspecific cultivar Alminsky
The experiment considered the influence of different
methods of agricultural technologies on the yield of
winter barley in the dependence of the investigated
factors. The studies were carried out at the
experimental station of Kuban State Agrarian
University in the conditions of multifactorial longterm
soil monitoring. The experiment was carried out
in a typical 11-field grain-grass-tillage crop rotation
with the following alternation of crops: alfalfa, alfalfa,
winter wheat, winter barley, sugar beet, winter wheat,
corn for grain, winter wheat, sunflower, winter wheat,
spring barley with sowing of alfalfa. Stationary
experience is represented by the following factors: the
level of fertility (factor A); fertilizer system (factor B);
plant protection system (factor C) and methods of
basic soil cultivation (factor D). The relationship
between the influence of the soil fertility level,
fertilizer norms, plant protection products, the soil
cultivation system and yield, and the crop structure of
the perspective winter barley variety ‘Gordey’ were
determined. The soil is chernozem leached superheavy
light-clay with an average thickness of the
humus horizon - 150 cm. It is found that fertilizer, soil
treatment, seeding method; protective means increase
the yield of winter barley and positively influences the
elements of the yield structure. The yield increase in
comparison with the control changed from 10.4 to 26.8
c / ha. The statistical processing data show that the
fertilizer system (35.8%) and soil cultivation (27%)
had a certain influence on the number of productive
stems; the fertilizer system (44.6%) influenced the
spike size, the fertilizer system (28%) and the tillage
(32.8%) had influence on the amount of grain in the
spike and influenced the mass of grain from the spike
The influence of different agricultural technologies on
the yield of winter barley variety ‘Gordei’ was studied.
Economic evaluation was given to the researched
factors. The studies were carried out at the
experimental station of Kuban State Agrarian
University in the conditions of polyfactorial long-term
soil monitoring. The soil is represented by strongly
leached, light-clay black humus with an average
thickness of the humus horizon - 150 cm. It was found
that with the change of technology (fertilizer, tillage,
sowing method, means of protection) winter barley
yields increases to 50% in comparison with the
control. According to the analysis of bioenergetic and
economic evaluation it makes sense to use the variants
022, 111 and 222 at plowing, where the maximum net
efficiency ratio and net income are noticed
The article is devoted to the various elements of the cultivation technology of winter wheat called Antonina with the application of different soil fertility backgrounds, fertilizer norms, and plant protection systems against weeds, pests and diseases. Investigations are carried out in a multivariate stationary experiment: factor ‘A’- soil fertility; 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 - medium (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 tillage: 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%. Based on examined researches it was found that for the sustainable yield of winter wheat the dose of mineral fertilizers should be increased, by that, the high quality of the grain is provided
Criteria of an estimation and a condition of antierosion actions on various types of the agrolandscapes providing the termination or minimizing of erosive processes of soil and increase of productivity of erosioned unproductive soils are resulted in the article
The inheritance of the “mass of 1000 grains” sign in the hybrids F1 and F2 was studied. Differences in the parental forms with 1-5 pairs of genes are revealed. The sources and the donors of the large-mass of grain are pointed, the indicative and genetic collections of the large-mass of grain forms of the grain sorghum are created
