In the article, the estimation results of reproductive, fattening and meat qualities of pigs of various types of nervous activity and state of cardiovascular system are given. The degree of influence of nervous activity on productive pig qualities has been shown
The article highlights the main aspects of the system of formation and reproduction of the resource potential of agricultural production. A number of systemic laws in relation to the process of reproduction study resources
The article is dedicated to the problem of different fat additives use in the rations for agricultural animals and poultry
The article presents the research results of eight grapes rhizogenesis of different genetic origin of the cuttings after treatment with 0.01% solution of IAA for 24 h. It was found, that the activity of regenerative processes in grape cuttings depends on the varietal characteristics, storage conditions and the activation of IAA. It leads to disruption of existing natural correlations, including suppressing the longitudinal polarity. Root-growing ability of cuttings is a genetically determined feature: the effect of IAA did not cause the stability of the positive reaction; it is determined by genotype and depends on the quality and physiological condition of the cuttings
The results of studying of influence of ways of sowing sorghum hybrids have shown that with increase in width of row-spacing, the crop of green weight and hay decreases, the high-quality crop of green weight is formed in the exit beginning in a tube
This article reviewed the results of analysis of a balance of nitrogen, phosphorus and potassium in chernozem (typical black leached soil of Belgorod region) after two crop rotations by different cultivation technologies of agricultural crops. The balance of nutritional elements has been calculated and the optimal agro technology for deficitless balance of plant nutritional elements determined
The article reviews the results of studies of adaptive properties of the hybrid corn of different groups of maturity at the background of anthropogenic factors. It discusses the practical application of research results in order to maximize grain yields from 1 ha, environmentally friendly products (including at cultivation of corn on the protected areas), economically viable crop with maximum return on investment, as well as the possibility of extensive corn cultivation technology with limited material resources-money producers
The effect of the level of milk production of firstcalf heifers on the further productivity, reproductive function and duration of economic exploitation of holstein cows in southern Russia
Correlation of finished and meat qualities of swine with biochemical and cytochemical indices of blood with the aim of selection of true tests for earlier estimation of productive qualities of animals are carried out and analyzing
This article presents the results of studies of the effect of different cultivation technologies of winter wheat on the content nutrition elements in the soil
