Size-mass indicators of soybean grown in Uzbekistan

Abstract

In Uzbekistan, soybean is planted as a main crop in early Spring and as a follow-up crop after wheat in Summer. In the conditions of Uzbekistan, the height of soybean grown as a main and repeated crop is 63-99 cm on average, depending on the species and cultivation techniques, the diameter of the stems in the lower part is 4.1-7.1 mm on average, and it is higher in “Oyjamol” and “Amigo” sorts planted in the early period, after wheat and it was lower in the Selekta-201 sort planted as a repeated crop. It was found that the pod placement height was higher than 15 cm in the “Oyjamol” and “Amigo” sorts, while it was 6 cm in the Selekta-201 species , and this indicated the need to set the combine harvester height lower. It was found that the average number of pods in one bush of soybean is 21.0 - 29.8 pieces, the number of grains in a pod is 2-3 pieces, and the ratio of grain to stem is in the range of 1:1 - 1:1.8. This showed that the “Oyjamol” and “Amigo” species planted in the early periods have more grain and stem content than the Selekta-201 sort planted as a repeated crop.

Theoretical and experimental determination of the dimensions of the slope and length of the feed distribution device for family livestock farms

“…According to the results of the above experiments, it was determined that the quality of distribution of corn, alfalfa and straw is at the required level when the slope of the pouring channel is 35°. The mass of distributed feed was 4.72 kg/m in corn, 4.42 kg/m in alfalfa and 3.62 kg/m in straw, meeting the requirements [7][8][9][10].…”

Structure and principle of operation of the apparatus for introducing chlorine into the process pipeline

“…As a result of the consideration of the existing methods of introducing chlorine into the treated water, the design of devices for mixing chlorine with water, a direction was identified that turned out to be promising, especially for a plant of small and medium capacity. This direction is the treatment of water with chlorine in the process pipeline [1][2][3].…”

“…Thus, in the apparatus for displacement of liquid and gas, the [3] presence of an additional twisting chamber makes it possible to intensify the mixing of liquid and gas, to create a stable gas-liquid phase during the time necessary for almost complete saturation of the liquid with gas, which is necessary for the treatment of natural waters.…”

“…In recent years, research has been carried out in our country and abroad to study and implement the dispersion of chlorine-air mixture directly in the process pipeline with the help of static mixers [1][2][3][4][5][6][7].…”

The balance of power consumption of the process of grain grinding

“…When conducting theoretical studies to determine the amount of energy spent on grinding grain during the operation of the grinder, the physical and mechanical properties of the grain were taken into account, the parameters and mode of operation were crushed, the energy consumption to overcome harmful resistances, to grind grain and to discard the crushed mass [11][12][13].…”
