In this article we present the results of studying the bioactive connections in bentonite clays and wastes of industrial processing of rice with the purpose of receiving a functional feed addition for poultry
In the article, we present a long-continued multiple-factor field experiment of agroecological monitoring to show the change of composition and balance of humus in leached black soil when cultivating field crops on Azov-Kuban lowland using different technologies.
The article compares the basic biotech properties of beef of new meat breeds and determines the potential of their use
Creation of joint sowings is very complicated modern environmental problem and the solution is impossible without a comprehensive study of the relationship between individuals of different species that are emerging at the level of a plant community. Studying biotic relationships between taxa used in these crops is very important; joint crops include combinations (sowing crops in rows) and mixed crops (crop seeds mixed and sown together); great attention in the mixed and combined sowings has been paid to selection and combination of cultures
The effectiveness of drug treatment of Korenastyi on productiveness and quality of sweet peppers and egg-plants was shown
The article presents the results of study of the reproductive capacity of landrace varieties of winter wheat on the example of the chief of the ear. Analysis of sales productivity was conducted by the method of F. M. Kuperman. We have also considered the relation of actual productivity number formed flowers on the 6th stage of ontogenesis
The article presents the results of the studies of the effect on heifers of Red Steppe breed and hybrids, inclueding their growth, form of the udder, milk production. The cows breed was improved by Ayrshire bulls and red -and-white Holsteins in the South zone of the Rostov region
This article presents the data of the research of new
feed additives’ effects on the dynamic of
hematological indexes and milk productivity of cows
The article represents the results of the experiments on biological activity of humits of different sorts. The object of research was humic preparation called Vermistar, which was obtained by vermiculturing, on the basis of brown coal. Humics are group of high-molecular substances which have high physiological activity. Humic substances stimulate all biochemical processes on all the stages of plant growth. They change the permeability of the cell membranes, increase activity of ferments, amount of chlorophyll and productivity of photosynthesis. Also humits are not toxic; they don’t have carcinogen and mutagenic effects, so we have a chance of getting environmentally friendly products. The experiment results show high biological activity of humic preparations. Usage of humic stimulates germination, the accumulation of vegetative mass, weight gain. The frequency of shoot has been increased by 17-32%. Height of shoots, roots and vegetative mass has also been increased
A comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation
