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
