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
This article provides an overview of the impact of the Prorastina and the Polistina biologically active preparations on sorghum grain productivity on light-chestnut soils of Kalmykia
In this article, the essentially new approach to a way of conducting the central conductor is considered, at formation of trees of an apple-tree on the system of “harmonious spindle”, as one of ways to increase the efficiency of an apple-tree on a stock of ММ-106 at the introduction into fructification in plantings of intensive type, with the placing scheme 5×2 m in the conditions of fertile soils of Krasnodar territory
In the article, the results of the analysis of agrometeorological factors of formation of a crop of long-term cultures are resulted. The regressive correlation analysis of the given conditions and growth of bean and cereal grasses has allowed to establish high correlation dependence between change of a crop and number of days of growth for cereal herbage. It is noticed, that change of the efficiency of the bean is less closely connected with time of formation of herbage, than cereals. Also, for fertilized bean and cereal the correlation factor between the crop and the term of growth of the grass is higher, than for not fertilized ones. The backward correlation dependence between the changes of the maintenance of a raw protein, ashes in a forage from the first hay crop of cereal herbage and, accordingly, the sum of temperatures more 5°С is established
The history of the spread of patisson on the example of agro-botanical illustration has been reviewed . The different forms of selected, dissemination and use in the modern world investigated
The article presents the research materials of viability of broiler chickens in bad conditions with pullorosis when exposed embryos and day-old chicks to radiant energy, the results of the content and lysozyme activity, bactericidal activity of serum lysozyme in relation to the test culture, the overall viability and survival of the birds in pullorosis in bad conditions

relationship of reproductive qualities of sows
measured at the index selection
The article highlights the biochemical characteristics of perspective newest varieties of table grapes and clones of the Kuban region; it also presents the results of the study in an industrial environment of OAO AF "South", OOO "Phanagoria-Agro", Training Farm "Kuban" and branches of the Department of Viticulture of Kuban State Agrarian University and in Farmer-amateur conditions of private entrepreneurs of Kuban
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
In the article, we have made an attempt to develop and calculate a model of humus content estimation in the black leached soil according to remote sensing of the ground. We have presented the model which has a number of restrictions for its continuous use when carrying out soil environmental monitoring of land grounds. It is established, that for calculation of similar model it is necessary to perform the cameral works including selection and the preliminary analysis of fields, including using of contemporary records of Remote sensing of the ground for definition of sampling points, to carry out an assessment of space photo shooting and sampling of soils in optimum terms with the maximum synchronism (cameral work and soil and agrochemical inspection), to make the analysis of the selected samples of soils for humus content with traditional methods, and finally to calculate regression models with use of data of the carried-out space shooting and the agrochemical analysis of soil samples
