A system for sowing seeds in cells of a germination tray or other container and related methods of operation. The system may include a conveyor configured to move the germination tray in a conveying direction, a seed storage container configured to hold a plurality of seeds, a seed sowing machine, and a seed diverting mechanism. The seed sowing machine may be configured to transfer the seeds from the seed storage container along at least one seed transport path and into respective cells of the germination tray as the conveyor moves the germination tray in the conveying direction. The seed diverting mechanism may be configured to selectively divert seeds from the at least one seed transport path such that the diverted seeds are not deposited in cells of the germination tray during operation.
