Theoretical Research on the Flight of Onion Seeds under Discharge from the Seeding Unit

One of the most important issues of sowing small-seeded crops (an example of onions) is considered. The method of sowing has a great influence on crop yields. The choice of planting method is due to the need for a more uniform distribution of plants over the field area in order to optimize the conditions for their development. Studying the movement of seeds during the sowing process is the most important task. Because, the object of sowing is the seeds. The article provides an analysis of previous work on the precision sowing of small seed crops. And also, the flight and the trajectory of the seeds from the ejection window to the bottom of the groove were studied theoretically. In research methods of higher mathematics were used, in which it was possible to obtain the necessary equation. Based on the numerical solution of the obtained equations, graphs are constructed that determine the path of onion seeds on the corresponding X and Y axes. It can be seen from the graphs that the flight path of the seeds changes according to the parabola law.
