We have studied the influence of dietary probiotics and metal salts, iron and copper, as detoxifiers for the negative factors which adversely affect the sanitary condition of feeds for farm animals. The optimal doses of detoxifiers in the food infected with mold
due to storage conditions were found. The positive effect was, on average, 8%
The article presents the results of the studies of 11
varieties cultivated in the eastern region of South Coast
wine-growing zone of Crimea (planting of
"Solnechnaja Dolina ", near Sudak mountain) in the
area of their natural growing, where was formed the
gene pool of grapes for a long time. As a result, the
three-year (2010-2012) study found that the majority
of indigenous varieties had small number of fruitbearing
shoots in the bush: the varieties with colored
berry - 53,3-73,3%, in white-berry - 46,6-75,9% except
Shabash variety - 79.9%. We have identified the most
productive varieties which were Dzhevat kara (62.2 t /
ha), Kokur Beliy (48.9 t / ha), Kapselsky Beliy (44.4 t /
ha), and varieties with female type of flower: Kefesiya,
Ekim kara, Kock pandas, Sary pandas and Crona gave
not high yield: 22.2; 22.2; 24.4; 28.9 and 28.9 t / ha.
On the strength of growth, productivity and the
accumulation of sugars in the juice of berries, we
picked out varieties of Dzhevat kara, Crona, Kapselsky
beliy. According to the main economic indicators, it
turned out that the most profitable varieties are
Dzhevat Kara, Kokur beliy and Kapselsky beliy.
Hence, these varieties in conditions of the Crimea have
much greater prospect of reproduction and
development of production
The total area of green spaces in the capital of Dagestan now stands at 3003.5 hectare, and in the mid-1960s - 186 hectares. Green areas of common use per capita in 2015 compared to 1960 has decreased dramatically and amounted to 3.6%, which is only 1.0% of the norm. The race of landscape construction of the city far behind the race of construction of residential and office sectors, and the existing green spaces either in quantity or quality does not matches the sanitary and aesthetic requirements, in addition there is a low level of artistic and architectural planning of green space. We have also described the questions of the history of the garden and the park building in Makhachkala and meticulously analyzed the rock-species (species, forms, varieties) of the composition of green space. We have marked the evaluation of their condition. Despite the great diversity of species composition (281 kind of woody plants, including 60 species of gymnosperms and angiosperms 221 views), we have noticed that almost everywhere there was cultivated only a small part of them. This is despite the fact, that the Republic of Dagestan has a rich species diversity of local flora, which can be effectively used in landscaping. Here, too, there are favorable climatic conditions for the introduction of new species. It should be noted that the private sector can be traced as having the opposite trend. Some recommendations have been given to improve the structure and condition of the trees and bushes planted in the city. Finally, we have shown the necessity of linking the production of green building works with the scientific activities of specialized education and research institutions in the city
The detailed morphological description of interspecific tomato F1 hybrids is represented in the article. The positive heterosis in regard to sire component was noticed in accordance with the following characteristics: fruit size, leaf size and stem length. It was established that the inclusion of tomato of Lycopersicon cheesmanii typicus genus into selection enables the obtaining of new species at the expense of increasing the range of genetic variability
The article shows the results of integrated assessment of variety-rootstock combinations of plum on clonal rootstocks and different schemes of landing. We have defined the basic biometric parameters of trees, and specific indicators of productivity, allowing to identify the most optimal variety-stable rootstock combination for the conditions of the Krasnodar region
The article presents an overview and in-depth analysis in the area of barley grain production. The statistical data and comparative analysis of total yield of barley in the Russian Federation with respect to other cultures, widely cultivated in our country, such as sunflowers, oats and wheat has been presented. The structure of sown areas occupied by the culture of barley in the Russian Federation for the period from 1990 to 2013 has been presented graphically; we have analyzed the trend of their increases and decreases over the years. The article presents and visually shows a comparative analysis of crops like winter and spring barley. At the same time, due to a significant warming, distinct advantages of winter crops to spring crops in the cultivation of them in the southern regions of the country have been noted. The recommendations on the feasibility of increasing the cultivated area were made. Indicated by the national economic significance of culture, we show the examples of its use in industrial processing. In addition, long-term analysis of statistical data on the yield of major crops grown in the Russian Federation, such as wheat, barley, maize, millet, oats, rice, legumes, sunflower, soybean has been performed
The influence of pumpkin variety on the increase of seed productivity on dark-chestnut soils of Rostov region has been revealed. A number of varieties of pumpkin, using of which will allow to increase the output of oil per hc, is offered.
Multiplex DNA-marker set for PCR identification for rice blast resistance genes Pi-40 and Pi-b was developed in this study. Optimal primers combinations and PCR conditions allows to identify both abovementioned genes in the single PCR
There was substantiated the purposefulness of introduction
in non-irrigated organic gardens of apple-trees of Kuban zone of in-row sodding of soil with naturally growing grasses providing the increase of plant resistance to abiotic stressors of summer period and as a consequence, stabilization of generative activity and the increase of fruit productivity
The effect of dietary supplementation with dry bakery yeast culture Saccharomyces cerevisiae in high concentrate diet (F:C=47:53) on milk yeald and rumen fermentation were studied on two groups primiparous lactaiting cows (8 cows per group) and four ruminally cannulated nonlactaiting cows on diet
F:C=25:75. Cows fed yeast during 67 days produced 1.24 kg/d and 1.66 kg/d natural and 4% fat corrected milk respectively more, than control cows. Milk protein and fat percentages were also higher. On diet with yeast ruminal concentration of lactate was lower and butirate+propionate was higher. The yeast
incrised rumen pH, decreased NH3 in rumen and urea in blood, decreased viscosity of rumen fluid
