In the conditions of Krasnodar region variety-rootstock combinations of plum Russian in the period of growth and fructification for the purpose of allocation of best of them for use in intensive technologies of cultivation are studied. The most weak, productive, fast-grown variety-rootstock combinations are allocated. They represent the greatest value for use in technologies of intensive type by production of fruits of Russian plum
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
In the article we have shown the results of the study of the treatment before laying hatching eggs for incubation, embryos at 6,12,18 days of incubation light bulbs CCB-15, CCB-30, OPL-150, DRT-400 at rates of embryonic development
In the article the effects of examinations on influence of a vascular necrosis on a survival of shanks of grapes of breed Saperavi inoculated on stock RхR 101-14 are introduced
In the article, the estimation of efficiency of selection on high tillering is given at various planting density. For the analysis used plants of variety Lampo with high tillering ability and varieties the Virazh and Ko-mandor - with weak tillering ability, and hybrid popu-lations F3 from their crossing, selected on traits high and low tillering from F2. Plants ¬ placed on plots in three variants: 2×15, 15×15, 30×30 cm. It is estab-lished that distinctions on tillering between “+” and “–” selection in following generation remain, though the value of given trait at hybrid plants decrease. Selection of highly tillering forms at usual density (2×15 cm) has shown high efficiency, because the tillering is caused by more influence of genetic factors, than environment in the given variant
The article considers the crop rotation with different saturation of rice and measures of struggle against the cereal and wetland weed

The article is about the influence of various norms of fertilizers on efficiency of three various by origin and zone varieties of middle fibrous cotton in steppezone of East PreCaucasis. The purpose of the research is the optimization of mineral food of non- irrigated cotton
The essential new approach to soil processing taking into account its origin as a geologically disperse body is offered. The soil should be processed not only using its natural dispersion, but also optimizing this geological deposit taking into account decrease in its dispersion in process of a geological and biological sedimentation in the field of weight of Earth. The new technical solution is proposed for rotational intra soil cultivation. The problem is solved to transfer a torque to the tool being inside the processed geological body
