Abstract
A system is provided 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 an agricultural field. The system may include a selector assembly arranged between a multi-compartment on-row hopper and a seed meter at each row unit of a planter. A control system controls selector valves of the selector assembly to switch from releasing of seeds of a first type from the on-row hopper the seed meter to releasing of seeds of a second type from the on-row hopper to the seed meter for providing a switchover of seeds being planted from the seed meter, from the first to the second type when the seed meter cross a boundary between different zones of the agricultural field.
