This research reviews an analysis of several problems of milk production process as well as fast methods of dairy cows' health control widely used in the countries of high-level dairy breeding. The results of milk analysis via test stripes reveal that about 30% of cows during transition period - phases transit 2 and 1st phase of lactation - have clinical and subclinical ketosis marks what comes as one of the reasons of cow's low productivity. Evaluation of cows' fatness evidence that only 46,4% of tested animals have normal fatness according to the appropriate lactation period, whereas other animals have too high fatness index and only very small part - 1% have extremely low fatness index. Cows' obesity leads in future to ketosis and disturbance in metabolism. The research also revealed nonconformities in boxes size, they do not satisfy requirements of comfortable Holstein cows handling. The article provides recommendations on implementation of tested methods based on survey in order to suggest the ways of milk production efficiency increase
Great practical and theoretical interest comes with a study of the transformation of calcium agrobiogeochemical in agro-ecosystems. The basis of the stability of the soil, as an element of the structure and functioning of the biosphere, constitutes historically approved biochemical cycles and flows of matter and energy, which remain unchanged under anthropogenic impact. Comparative analysis of the total content of calcium leached black soil allowed us to establish its decline after three rotations of grain and grass-tilled crop rotation. Without the use of fertilizers its reduction from baseline was 5.25% in the layer 0-20 cm and 3.87% in the 20-40 cm layer, with their introduction - 9.14 and 9.35%, respectively. This trend suggests a decrease in calcium reserves in the root zone of leached black soil in its agricultural use; this process is more active when using mineral fertilizers. This is obviously due to a large outflow of elements in the fertilizer background with harvest crops, and partly due to the influence of mineral fertilizers as chemical reagents on mineral soils, resulting in the release of calcium and moving it into the lower soil horizons. Along with the total content of calcium and its forms, we have analyzed the activity of calcium ions and calcium potential
In the conditions of foothill soil-climatic zones of the Republic of Dagestan we have explored the creation of low-cost intensive apple orchards. This work was initiated by the authors in 2011 due to the Republic "Horticulture Development Program for 2011-2016", according to which, it was planned to plant 6,200 hectares of new gardens. However, the experience of gardening in the Republic, taking into account recently prevailing socio-economic relations, subsidized nature of the economic and a chronic lack of funds, shows the riskiness of the creation of high-tech pillar-dwarf plants with the cost of 1-1,5 million rubles per hectare. Inability to overcome quickly the existing problems in the development of the industry sharp gardening at this stage, forced us to seek a way in a single direction - reducing the cost of the creation of apple orchards, while maintaining their high economic efficiency. Theoretical studies were realized as a planting of the apple garden in the district of Karabudakhkent of Dagestan of four perspective late-ripening varieties on the medium growing rootstock in the spring of 2013. The results of the three years of scientific research were embodied in the creation of intensive apple garden on the medium growing rootstock which allow now to make the following preliminary conclusions: 1.It is possible here in Dagestan to create intensive apple orchards, with an estimated yield of 30-40 tons per hectare, on the medium growing rootstock already at a density of 666 trees per hectare. 2. Cost of such a garden, without compromising quality indicators, can be reduced in the current market price of labor and the necessary materials, up to 214 thousand rubles per hectare, with access to the full return of all costs in the seventh year of operation. Such intensive garden, according to common practice, during the period of operation is able to give at least 22 full-weighty harvests and provide a net profit about 6.6 million rubles per hectare, or 236,000 rubles per hectare per year for the entire period of alienation of the land for a garden
The article presents three-year data on the influence of different fertilization systems and predecessors (corn for silage and peas) of winter wheat in the rotation on the dynamics of content in the 0-20 cm layer of black leached soil of mineral nitrogen, of available phosphorus, of potassium, and yield of winter wheat. The materials presented in this article indicate that, regardless of its predecessor in all phases of plant development, the under study fertilizer systems significantly increased the content of mineral nitrogen on the indicators of natural agrochemical background on 1,1-29,3 mg/kg; maximum contents was registered in the settlement system of fertilizer. After a seeded fallow predecessor the fertilizer systems significantly increased the content of available phosphorus in the soil at 1,5-16,6 mg/kg and exchangeable potassium in the 6-57 mg/kg. The maximum indices of both indicators were observed in the settlement system of fertilizer. Analyzed fertilizer systems contributed to a significant increase in wheat yield relatively to control 0,82-2,24 t/ha on a busy couple 0,74-1,6 t/ha for maize silage, 1,44-2,42 t/ha peas. Maximum productivity of winter wheat in the experiment was fixed at the fertilizer system after a busy couple, and was 6,19 t/ha
Increasing the yield of crops is a global challenge substantiated by the scientists from all over the world. To achieve this goal, there are various ways, one of which is the ozonation of seeds before sowing. This method inhibits harmful microflora, which could be formed on the seed during the period of storage, and excites the chemical processes within the seed that can accelerate the process of growth. But despite the positive effect of ozone-air mixture of seeds and a variety of conducting research there is still no reliable data on the technological parameters of ozone effects on seed crops (e.g., corn). In this regard, we have conducted experimental studies to determine the effective parameters of the ozonation of corn seeds, such as the concentration of ozone in the ozone-air mixture, exposure time and binning after treatment. The influence of these parameters was assessed by changes in growth performance of seed, such as germination, germination and growth of strength. Just at the end of the pilot study we carried out a statistical analysis of the data, which allowed us to estimate the degree of influence of each independent parameter (ozone concentration, exposure time, binning after treatment) for each dependent parameter (germination energy, germination, growth force). The data obtained is presented in the article
