• a plurality of row units operatively connected to the plurality of seed tanks for receiving the varieties of seed, the row units each comprising:
• a seed meter comprising:
• a. a substantially circular, rotatable seed drum;
• b. a plurality of seed paths comprising a plurality of seed cells spaced about the seed drum each of said seed paths corresponding to one of the variety of seed types to be planted and each of the seed paths adjacent to one another on a single drum;
• c. a seed exit path;
• and
• d. a discharge mechanism selectively operable with at least one of the plurality of seed paths such that operation of the discharge mechanism with a seed path will discharge a seed variety associated with said path from the seed cells to the seed exit path;
• and
