A system for planting multiple types of seed and automatically switching between the varieties during planting in a single planting pass of a planting session of row-crop planting of an agricultural field while controlling seed delivery speed to mitigate seed bounce and/or provide desired seed spacing distances. The system may include a bulk storage system, an on-row storage system, and a charging system that selectively delivers seeds of different varieties from the bulk storage system to the on-row storage system and a seed delivery speed control system that regulates seed delivery speed.
