There were presented the results of the researches on study of regeneration properties of grape grafts of the Saperavi variety prepared from bushes which were treated with solutions of the “Vympel” preparation and mineral fertilizers of new generation – Nutrivant Plus and Kelik potassium silicon for vegetation period
three times. There was studied the influence of preparations on productivity volume from a bush and as well as main indexes of spear- and root-formation ability of grafts; there were determined the presence and degree of correlation connections between productivity from a bush and size characteristics of
spears in low zone, as well as the degree of graft maturing and hormone activity of wintering buds on them on the one hand and indexes of root-formation ability of grafts on other hand
This article considers a possibility of increasing adaptive potential of stevia - native substitute of sugar impacting with influence of processing BAS of green apical sprigs used for receiving seedlings
In the long-term stationary experiment since 1968, we have studied the influence of crop rotation on soil fertility and productivity. The modernization schemes of field rotations in the direction of alternation crop change were held 40 years later, by introducing a scheme of oilseeds (canola, soy). According to the research, the authors made conclusions about the efficiency of cultivation of oil crops in crop rotations in the region. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia
The article presents the results of researches of the
different systems of basic treatment of soil under a
sunflower on a closeness, aggregate composition,
supplies of productive moisture on regular black soil
of the Krasnodar region
The assessment of quantitative signs of plants of peas and comparison of hybrid lines of leafless peas and leaves morphotypes is carried out. Lines of peas which are more productive and most adapted for the south Rostov region conditions were allocated as a result
The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention
The article deals with the problem of growing geese and explores the possibility of feeding young geese with rapeseeds of 00-type and their products
In the article we present the results of the researches
on the study of the different systems of basic treatment
of soil on the plants of sunflower, as well as its
infestation by one-year and perennial weeds and its
productivity on usual black soils of the Krasnodar
region
The article presents the results of studies on the influence of predecessors and funds of intensification on the yield of spring wheat in the field crop rotations. Studies carried out in the long stationary experiment in crop rotations over the past seven rotations. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia
The article presents the biological growth of above-ground parts in a nursery open ground. It gives the economic evaluation of the production of seed species and varieties of juniper, depending on the category of the source material
