In the conditions of grey forest soils in the Bryansk
region among the fodder crops widespread mixed legume-cereal
crops. The results showed that the photosynthetic
activity of cereals and leguminous crops and
their yields in mixed crops depended on made of biological
and mineral nitrogen fertilizers. It is established
that the nitrogen in the form of ammonium nitrate has
a positive impact on the formation of assimilating leaf
surface, photosynthetic potential and net productivity
and yield of grain mixture in lupine-barley and soybean
-barley cropping and pea-barley crops the use of
nitrogen in the form of potassium nitrate was more
favorable. It was found that in lupine-barley crops the
active symbiotic potential has increased by 25,5% and
the yield increased by 21,3% , in soybean-barley crops
28,5% and 19,2% respectively, due to the joint use of a
mixture of symbiotic and associative rhizobacteria and
mineral nitrogen in the form of ammonium nitrate in
the dose of N60. In pea-barley agrocenosis it has improved
the efficiency of cultivation of joint application
of mixed inoculant symbiotic and associative rhizobacteria
on the background of the application of mineral
nitrogen in the form of potassium nitrate in the dose of
N60, where there was an increase of the active symbiotic
potential by 34,7% and grain yield by 24,7% compared
to the option when adding the mixture of biological
products
In this article we studied period and methods for soil treatment after alfalfa and their effects on soil fertility and productivity of the Rapan rice variety
In the article we have proposed the technology of repair works using improved soil mixture sifting the rubble and ash using soil mixture installation and without it. For prevention of occurrence of defects and damages we have offered an antifiltration device
in the form of screen and core from compacted obliquely pulled layers of impermeable soil
The optimum conditions of cultivation of probiotic association bacteria (structures of mother waters and industrial nutritious environments, optimum of temperature and time of cultivation) are determined; therefore it was allowed to develop the “know-how” of the Bacell fodder additive. On the basis of the carried out experiments of the application of Bacell on birds it is possible to make a conclusion about expediency of its application at cultivation of the hens as the fodder additive. Its use allows to increase efficiency, safety layers, and to increase the competitiveness of manufacture of eggs and meat of the hens in general
The results of evaluation of physical and chemical properties of pork with disabilities, PSE and DFD de-fects for 6 days and the changes occurring in the pro-cess of glycogenolysis are presented in the article
The article substantiates the necessity of the use of the whole complex of the zonal agricultural activities as the most important components of the integrated protection of plants from weeds, pests and diseases, strict observance of which contributes not only to a substantial increase in biomass sweet sorghum, but also the cultivation of certified seeds free from the infection
The application of bioactive preparations during taking root of green cuttings conifers family of Cupressaceae has been described in this article. Longstanding experiments of growing planting stock with open and closed roots have been realized. Increase of taking
root, apical growth and development of root’s system by positive influence of preparations has been shown
The work on the development of technology for production of feed additives from soybean seeds and fruits of pumpkin has shown that the use of sodium bisulfate and lactic acid bacteria provide a high content of carotene in pumpkin paste (948 mg / kg and 819 mg / kg, respectively), and grinding soy before drying protein and vitamin supplements raises safety of carotene without destroying the urease
In this article tendencies of vegetable production manufacturing in all categories of facilities of Krasnodar region are analyzed. Problems of increasing of an overall performance of agrarian and industrial complex are proved.
With the possible radioactive contamination of the
territory, as a result of emergency situations at
enterprises of the nuclear fuel cycle, there occurs a
task of further use of the soil for agricultural purposes.
Researches on the cultivation on contaminated areas of
fruit plants in the conditions of the Krasnodar region
were not carried out. As a result of the experiment in
the field we received experimental material on
migration and 90Sr accumulation in vegetative and
generative organs of cherry-plum. Research lasted for
8 years. The accumulation of 90Sr, placed on the
surface of the soil, in the bark, wood, leaves, and fruit
was 7,0×102
; 4,8×102
; 9,7×102
and 1.8 ×102Bq/kg.
With the penetration of 90Sr in soil at 50 cm
accumulation in the bark, wood, leaves, and fruit were:
5,1×102
; 3,0×102
; 6,9×102
; 1,4×102Bq/kg. The
experimental material obtained in the field makes it
possible to calculate the coefficients of the nuclide
transition from polluted soil to the various organs of
the studied plant and to make a forecast of the possible
use of contaminated areas for the cultivation of fruit
crops. Radioactive contaminated areas cannot be left
without proper control, since, firstly, non-planted
fields are exposed to wind and water erosion of soils,
which leads to rapid and large-scale pollution of the
environment and, secondly, if it is possible to obtain
products from such fields, this should be done for
economic reasons
