The effectiveness of methods of caring for corn crops placed against the background of agricultural technologies of varying intensity has been studied. So, by the end of the growing season of corn, the highest weediness of crops was noted against the background of intensive technology - 350pcs/m2 with the lowest grain productivity - 34.0c/ha. The number of perennial weeds was also 130.0 specimens per 1m2. In the variant with basic agricultural technology, these indicators are reduced: in terms of total weediness of crops to 110.0 weeds/m2, perennials - up to 120.0 pcs/m2 with a grain yield of 42.5 centners/ha. Given the placement of corn crops against the background of intensive agricultural technology, the indicators of technical and economic efficiency increase. Thus, the level of crop cleansing is 73.4% in terms of the total number of weeds, incl. perennial group of weeds dies by 56.2%. This ensures the formation of grain crop production up to 47.6 c/ha and is saved from losses up to 13.6 c/ha of grain compared to the data obtained against the background of the use of extensive agricultural technology. In the variant of the technology of increased intensity (T-4.), these figures are even higher - 95.0% of the death of the total mass of weeds with a corn grain yield of 50.8 c/ha with an additional gain of up to 16.8 c/ha.

However, the use of chemicals causes environmental pollution and is accompanied by significant investments of material and energy resources. In addition, there is a decrease in humus in the soil. Therefore, agrotechnical techniques aimed at maintaining the natural fertility of the soil and stimulating the development of soil microflora are very relevant. Currently, natural growth regulators and bacterial preparations designed to activate the metabolic processes of plants and increase their productivity are increasingly used in crop production. Biological products can affect plants at different stages of growth and development. But their influence is most effectively manifested in the process of seed treatment before sowing. Such seeds have a high plasticity to changes in environmental conditions. And the use of drugs has a multifunctional effect. The article presents research materials on the effectiveness of the use of a new-generation biological product and micro-fertilizer, as well as zeolite-containing clays as a pre-sowing treatment of clover seeds. We used \"Albit \"(a complex biological product), \"Polydon Bio Bean\" (micro-fertilizer) and a mixture of rhizotorphin with \"Alanite\" (zeolite-containing clay). The results of the conducted studies revealed differences in the germination energy and germination of seeds of different types of clover. The influence of meteorological conditions and ecological and geographical origin on hard - seeding is determined. The seeds were treated with rhizotorphin and thiamine. Various doses of Alanite were tested in a mixture with risotorphin. The best option is a mixture of 1:5, which increased germination (37%), seed productivity (84%) and nitrogen-fixing ability. Both drugs had a stimulating effect on the germination energy and seed germination (15 – 28%). The acceleration of the development phases, an increase in the number of generative stems, the number of inflorescences, and foliage were noted. The yield of green mass for 2 mowing increased by 130 c/ha. The qualitative composition of the feed mass has also improved.","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88187158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of the conducted studies, it was found that it is advisable to use a nanodispersed aluminum oxide powder as a nanoscale phase. The method of mathematical planning of the experiment was used to determine the optimal modes of coating and the concentration of nanoscale particles in the electrolyte. The microhardness of the obtained coatings was chosen as an optimization parameter, since it significantly affects their wear resistance. The highest microhardness of a nanocomposite electrolytic coating based on chromium is achieved when the electrolyte is heated to a temperature of 50 °C, a current density of 59 A/dm2 and a concentration of nanoscale phase particles in the electrolyte of 3.2 g/l, which ultimately corresponds to an increase in microhardness to 14.32 GPa. It is also established that nanocomposition coatings have a positive microhardness gradient in thickness, which allows leveling the difference in the values of the microhardness of the coatings and the base metal and will help to increase the adhesion strength of the coatings to the base on the one hand and their wear resistance on the other. Based on the microhardness measurements of chromium-based nanocomposition coatings, statistical series were formed. 30 samples were subjected to measurements. According to the results of microhardness measurements, the average square deviation of the values of nanocomposition coatings based on chromium was 0.05 (coefficient of variation 0.283). To equalize the obtained experimental microhardness information, the law of normal distribution is chosen, since the coefficient of variation, according to which the greatest probability of microhardness values of nanocomposite coatings based on chromium is observed in the range of 14.32–14.37 GPa.","PeriodicalId":14015,"journal":{"name":"International Journal of Life-Sciences Scientific Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79632355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant temperature changes in the cowshed during the seasons have a negative impact on the behavior and health of the animal. Excessive temperature and humidity readings lead to a deterioration of appetite, a decrease in feed consumption and a decrease in animal productivity. At low temperatures, there is an increased consumption of feed, which is associated with the need to obtain energy aimed at warming the body without a positive effect on milk productivity. Also, under equal microclimatic conditions of cowsheds, a more positive effect on the economic and useful indicators of Siberian cows with a loose method of maintenance compared to a tethered one was noted. With loose technology, cows have the best indicators of resistant qualities, metabolism and milk productivity, while increasing the automation of production processes, increasing the level of labor and profitability of production.

The differential function of the efficiency of restoring the operational properties of the engine is presented. To solve the existing problem, studies were carried out to simulate the process of removing deposits from the lubrication system with flushing oil. It has been established that used engine oil purified with clarification can be used as the basis for flushing oil. The dependence of the change in the contamination of the surface of the oil pipeline and the content of insoluble sediment in the oil on the time of flushing the lubrication system with purified waste oil has been obtained. A decrease in the contamination of the surface of the oil pipeline from 10 to 7 points and an increase in the content of insoluble impurities in the oil from 0.01% to 0.20% were determined. It was found that the addition of diesel fuel to the purified waste oil in the amount of 3% by volume does not lead to a significant increase in the washing properties of the oil. Additional enrichment of the cleaning mixture, consisting of purified used engine oil, 3% diesel fuel and potassium isopropoxide 3% wt, 3% wt dimethyl sulfoxide, reduces the point of contamination of the oil pipeline surface from 10 to 1 point.

Various cataclysms, such as floods, droughts, lead to a shortage of food and feed. Among all cataclysms, drought is the main destructive natural disaster, leading to significant loss of vegetation. On average, about 30-40% of the cultivated area in areas affected by drought. Also, drought causes another type of loss when the growth rate of plants is limited. In such conditions in the regions, there is an acute shortage of feed and fodder. Therefore, there is a need to develop feeding strategies for keeping animals to ensure their development and productivity. Feeding strategies during times of scarcity depend on the specific conditions prevailing in any particular area. In general, the farmer must make decisions based on economics, knowledge of nutrition, availability of forage resources in difficult climatic conditions. Technological issues of feed preparation cannot be considered in isolation from the processes of digestion and metabolism in the animal body. Canned and treated with chemicals and other substances have specific nutritional properties and affect the animal's body, milk production and weight gain in different ways.
