Five-year data of the influence of direct affect and the post action of decomposed turkey droppings on the sunflower husk on crop productivity in three-level field crop rotation of spring barley - sunflower -spring barley and in a comparison of its action with the effect of fertilizers on crop yields were presented in the article. The affect of the droppings exceeded affect of mineral fertilizers on the productivity of field crop ro-tation link in a dose of N90P90K90 on 0,79 t/ ga or on 16%
The cost-effectiveness of animal husbandry in the conditions of Yakutia causes irreparable damage to viral diseases, such as salmonellosis, viral hepatitis, parvovirus enteritis and others. Based on this, in animal husbandry, increased attention is paid to the prevention of viral diseases. The work was carried out in the period from 2009 to 2012. in the conditions of LLC "Pokrovskoye animal husbandry" of the Khangalassky ulus of the Sakha Republic (Yakutia). Boning of young animals showed that all his indicators were higher for pups born in 2011. So body size and physique are rated higher by 15.15%, in males - by 20.58%. Hair color was better in females by 19.44%, in males by 22.66%. As a result, the classiness of the animals of the experimental groups was higher than that of pups born in 2010. The commodity properties of the animal products of experimental animals and its cost are consistent with the results of the valuation. The offset on the quality of the fur products of the experimental groups in 2011 was determined at 89.02%, which is higher than the 2010 results by 10.32%. The average cost of one fur of a silver-black fox in 2011 was 2225.62 rubles. Additional vaccination of the main herd of foxes in autumn against the viral diseases with the vaccine "Multikan-6" has a positive effect on the quality of the fur products. The economic effect amounted to 258.62 rubles per 1 skin of a silver-black fox (at 2020 prices)
We studied the resistance of the eight strains of oil-destructive actinomycetes, isolated from the oil-contaminated ecosystems to heavy metal salts when cultivatiwng with different carbon sources. Furthermore we researched feasibility to use those microorganisms for bioremediation of oil- contaminated sites with high level of heavy metals
In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear
Grapes are product of areas. Grape plant is very plastic
and can grow on almost all types of soils except highly
saline, fusion and wetlands. In studies of many
authors, it was indicated the influence of different soil
types and their properties on the growth of the vine
plants, the quality of berries and their products. The
object of study is soils and vines growing on them,
laws and processes affecting the formation of grape
production. Research methods are expeditions, field
and laboratory. The article presents data on the effect
of agrochemical soil properties (pH, solid residue, the
amount of aqueous extract ions, chlorine ions,
alkalinity (НSO3¯), calcium ion, magnesium ion, total
carbonate, active carbonates, nitrate nitrogen, mobile
phosphorus, exchangeable potassium , humus, humus
reserves) on the formation of the harvest of grapes and
wine products (tasting score, the extract, the amount of
phenolic compounds, the amount of organic acids, the
amount of amino acids, metal ions, potassium ions,
sodium metal, magnesium ions, calcium ions, the
amount of metal ions). With the help of statistical data,
we can establish the effect of weather conditions on the formation of 2009-2011 qualitative wines of
Cabernet Sauvignon
The article presents the results of the research of the density of wood, affected by various types of fire. The analysis of structural changes in the wood, based on its micro and macro structure is given
Increased range of Syringa in landscaping is a topical issue. They are very decorative shrubs, more and more widely used in landscape design. Study of vegetative propagation of plants, with the use of growth regulators, was conducted to identify the most perspective stimulator and to reduce the terms of the finished product. Syringa refers to bad rooting cultures. However, the methods of green propagation of cuttings with the use of growth stimulators not only propagate a culture, but also increase the yield of landing products. The article considers the technology propagation by cuttings of this promising shrub. It also shows the effect of growth stimulators: radifarma and HB-101, used for soaking of cuttings. According to the research, we have found an apparent benefits effect of the processing of cuttings with the stimulators on growth and development of root system. The analysis of the tables of rooting rate of cuttings shows the positive development of cuttings in the processing of the growth regulators. We have obtained the experimental data allowing to define which varieties distinguished by the greatest rooting and duration rooting among all the studied cultivars. Thus, the studies show that the use of growth stimulators with propagation of Syringa cuttings is an effective way of reproduction
The effects of increased water temperatures on the reproductive characteristics of rainbow trout females were studied. It was found, that the increased water temperatures produced negative effects on the gonad maturation and survival of the embryos when acted at the late stages (IV and V) of female gametogenesis, but not at the earlier (III) stage
This article presents the data of the research of new
feed additives’ effects on the dynamic of
hematological indexes and milk productivity of cows
To solve the problems of full-value feeding for pigs, it is offered to use protein-vitamin-mineral additives as a component of rations. It allows increasing live weight gain, average live weight gain and improving feed conversion efficiency per 1kg of live weight gain
