The article is an analysis of the results of three years of work with sexing sperm in one of the two farms of the Kuban region which have implemented this tech-nology
In the process of long evolution chestnut soils of the Eastern Ciscaucasia passed hydro morph, semi and auto stages of soil formation, accompanied by the leaching of salt, carbonates and dehumidification
Increasing the productivity of agricultural plants,
including rice, is the most important area of breeding.
The creation of varieties with vertically leaved
architectonics allows to have a qualitative approach
not only to the process of formation of a highly
productive agrocenosis, but also to solve questions of
assessing the productivity of rice. To create highly
productive varieties, it is necessary to develop new,
more efficient methods of selection
Series of field and laboratory studies were conducted from 2011 to 2012 in Russian State Agrarian University to evaluate a collection of 4 turf grass species and 15 cultivars for quality, summer density, ground cover and germination percentage. During 2 experimental seasons the plants have been growing with the extensive treatments. Turf quality was evaluated visually using a 1 to 9 scale. The two-way analysis of variance was used to identify genotype’s effects on density, ground cover and germination percentage
In this article, the results of the research of quality
characteristics of Russian rice varieties were observed
In this article we present the results of the evaluation of 20 red currant varieties from NCRRIHV collection. Evaluation of varieties for commercial quality and biochemical composition of berries are presented
The features of growth dynamics on diameter of 120-160-year-old seed and second growth oak trees, allowing identifying accurately the origin on the nature of age-related trends are examined. Figures and diagrams are given for growth oscillations on the diameter of trees of seed and second growth origin for the entire period of their lives
The results of analysis of physical and chemical studies, biometrical traits, amylose and protein content in hybrid combinations, lines, varietal samples are presented in the article. 5 samples with high nutritional value were identified during our research
Characteristic of chemical composition of varieties of grape cultivated in the Central zone of Krasnodar region and quality of juice produced from them is given in the article. Varieties for manufacturing of high-quality juices are recommended
The experiments were conducted on bull-calf of Kazakh white breed at the age of 12 months. In the capacity of feed additives there were used "Yoddar-Zn", which consists of microelements as iodine and zinc in organic form, and the additive "Glimalask-Vet" based on organic acids (I gr.). A second group of animals received only a basic diet with "Yoddar-Zn» (II gr.) feed additives. In the organism of experimental groups of calves, the transformation proceeded more intensively for nutrient feed. This has contributed to increase the intensity of their growth, slaughter performance and the quality of the resulting beef. Bulls that received a ration feed additives had a live weight more on 35,9, and 20,4 kg, carcass weight after slaughter - at 22,27 and 11,47 kg, and the mass of flesh - at 20,9 and 8,50 kg., compared with the control. The average sample flesh of carcass fat content was higher by 1,25 and 0,74%, protein – 0,68 and 0,47%, iodine - at 39,30 and 26,71%. The animals of experimental groups in the edible portion of the carcass was synthesized as compared to control, more protein on 5,86 and 10,71% and energy - on 10,95 and 5,02%. The highest efficiency established at complex using both feed additives. Estimation of economic efficiency of use of these feed additives showed a decrease in cost and increase in profitability of beef production
