The article presents the results of comparative field experimental studies of pneumatic seeders in terms of accuracy of stacking of maize seeds along the length of the row.
Analyzing the results obtained, it can be noted that all of the above pneumatic seeders can provide a sufficiently high accuracy of placement of maize seeds along the length of the line.
For all three brands is characterized by a decrease in the accuracy of seed placement in a row with an increase in the working speed of the sowing unit. There is also an increase in the deviation of the mean values of intervals between seeds and with an increase in the rate of introduction.
The best precision of plant placement in a row is provided by the Multicorn SK seeder, it has a higher performance than all other working speeds and rates. Seeders UPS-12 and SU-12 provide approximately the same accuracy, while slightly inferior to the foreign analogue.
