PROVING THE INNOVATIVE MANUAL HAR-VESTING TECHNOLOGY AND GREEN LEAF PROCESSING IN ONE FLOW
Description
Research results on elaboration manual harvesting technology and green leaf processing in one flow for farmers are presented. The result of proposed technology is decreasing labor expenses in 1.3–1.4 times and related costs on 20–25 % compared to manual harvesting and preparation leaves for curing

05.20.00 Processes and machines of agroengineering systems
Description
We present results on proving parameters of the device for maintaining uniform flow of liquid in hydraulic row sowing machine for seedling plants. Main difference between row sowing in greenhouse and in field is 10 to 20 times less width between rows. Existing sowing machines (because of little width between rows) can only perform scattered sowing. A method and a scheme of the device for maintaining uniform flow of polydispersed system (working liquid – seeds of seedling plants) are theoretically proved. Parameters of the device for maintaining uniform flow of polydispersed system (working liquid – seeds of seedling plants) are experimentally proved. We have also defined the effect of pipe’s position in the tank on flow of polydispersed system out of it and the effect of polydispersed system parameters (working liquid – seeds of seedling plants) on peculiarities of hydraulic sowing technological process. Testing the experimental row sowing machine for seedling plants determined that this machine adequately performs sowing process and increases productivity 8.3 times compared to manual sowing

05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
Description
The article presents results of theoretical and experimental studies on the justification and experimental confirmation of the influence of hydraulic seeding process modes on the parameters of row seeding technology for seedling crops. It is hypothesized that it is possible to ensure a uniform depth of seeding within 0.5...1.5 mm by feeding seeds into the soil by hydraulic means using a liquid. We have compiled a nomogram of the influence of the height of the initial level of the liquid and its density on the amount of pressure exerted by it on the soil. It was found that the pressure of the polydisperse system on the soil increases with both the density of the liquid and the height of the initial liquid level. Experimental studies have been conducted to study the effect of the pressure exerted by the liquid on the soil and the speed of the drill on the depth of furrow formation and the depth of wetting the soil. The article determines empirical dependences of furrow depth on the pressure exerted on it for different types of soils. It is found that the depth of soil wetting decreases with increasing speed of the drill
