The purpose of the research is to study the effect of the feeding area of Gala potato, the use of fungicides on the yield and quality of tubers in the Middle Urals. This research was carried out on the experimental field of the educational and experimental farm “Uralets” of the Ural State Agrarian University, the village “Studencheskiy”, during 2016-2018, in the climatic zone of the Middle Urals. The feeding area influenced the mineral and biochemical composition of tubers, especially the content of nitrogen, phosphorus, potassium, dry matter, vitamin C and others. The calculation of the economic efficiency of potato showed that during the years of research, the production cost fluctuated within the range of 4446 - 9446 rubles/ton, the profit from 63 724 to 269 172 rubles/ha and the level of profitability in the range of 24.66-165.43%.
Introduction: Small bowel obstruction (SBO) is defined as a complete and persistent cessation of the transit of materials and gases. It occurs in a segment of the digestive tract located between the pylorus and the colorectal junction. Herein, we report a case of small bowel obstruction (SBO) following excessive consumption of wild grapes with no previous abdomen medical or surgical history. Presentation of case: A 65-year-old male farmer presented with cessation of materials and gas associated with vomiting of food and then bilious. The abdomen was bloated and painful on palpation with a moving, painful mass in the left iliac fossa. The hypothesis of acute occlusion of the colon was retained and confirmed on the X-Ray which showed a dilation of small bowel with air-fluid levels. The diagnostic of acute SBO was retained. We performed urgently a median laparotomy. We found the dilation of the loops from the jejunum to the sigmoid colon with a compact mass at the sigmoid colon of 15 cm in length and 6 cm in diameter. We proceeded to crush the mass that was made up with wild grape seed fecal, and push it back to the rectum. The phytobezoar made up with wild grape seeds was extracted through the anus with the fingers after anal dilation.
The objective of this research is to study the manifestation of the main diseases of potato during the vegetation period of plants and storage of tubers. The research was carried out on the experimental field of the educational and experimental farm “Uralets” of the Ural State Agrarian University (USAU), the village “Studencheskiy”, during 2016-2018 in the climatic zone of the Middle Urals. According to the results of the research carried out, it was found that with the use of the optimal feeding area and the fungicide shirlan in the fight against pathogens, it was possible to obtain a yield of 36.6 t/ha, which is 31.1% higher than the control (factor A). At the same time, the cost price amounted to 4,446 rubles/ton, profit – 269,172 rubles/ha, and profitability – 165.43%.
Potato is the most important agricultural crop in the world and in Russia. Currently, in production are used varieties of domestic and foreign selection. Along with the yield, the products obtained are of great importance, according to which the intended purpose of a particular variety is determined. The study of the quality indicators of potato tubers is an integral part of the development of varietal cultivation technology. The purpose of the research is to study the qualitative indicators of potato tubers of the Gala variety at different plant densities and the use of fungicides in the Middle Urals. The research was carried out in 2018-2019 on the experimental field of the educational and experimental farm of the Ural State Agrarian University. The object of research is a medium-early high-yielding potato variety Gala. When conducting biochemical and agrochemical studies, gravimetric, extraction, ebuliostatic, ionometric and photometric methods were used. The electrical conductivity of tubers was determined with a conduct meter in mSm, the concentration of cell juice with a refract meter in %, nitrates in tubers – with a nitrate tester in mg/kg, the acidity (pH) of tubers – with a pH meter. The research results showed that the concentration of potato tubers cell juice decreases from 7.0 to 2.65% with an increase in the feeding area from 1400 to 2800 cm2. The use of fungicides shirlan and infinito reduces the electrical conductivity. The specific weight of potato tubers increases with an increase in the feeding area from 0.92 to 1.16 grams. The nitrate content decreased with an increase in the feeding area and the use of fungicides from 340 to 326 mg/kg. During the growing period, the content of carbon dioxide (CO2) of the potato plant in the control variant was 775, and with the use of shirlan it was 1043, which is an increase of 1.5 times. The scientific novelty lies in the fact that for the first time in the conditions of the Middle Urals, an assessment of tubers was carried out according to physiological, agrophysical and agrochemical indicators with new devices during the periods of storage of tubers (April) and vegetation of potato plants, depending on the feeding area and the use of fungicides.
The simultaneous double volvulus of the transverse colon and sigmoid in the same patient is a rare cause of intestinal occlusion. Two cases were observed in general surgery in Kati. Its clinical symptomatology does not differ from other occlusions as well as simple radiological images. It is an extreme surgical emergency, the diagnosis is generally intraoperative. Extensive left hemicolectomy with terminoterminal rectal anastomosis was performed. The surgical follow-up was simple.
