A seed meter is provided for planting multiple types of seed and rapidlyswitchingbetween the types being planted in a single planting pass of a plantingsession of row-cropplanting. The seed meter has a segmented seed meter reservoir with multipleseedmeter chambers arranged between two pairs of seed disks that may be betterparallel toeach other or angled with respect to each other to define an X-shapedarrangement of theseed disks in the seed meter. Activation and deactivation of the seed diskswithin the seedmeter are synchronized to selectively deliver a single one of the multipletypes of seedfrom the respective seed meter chamber for delivery out of a single seed tubeof the seedmeter, which may provide absolute and instantaneous on-the-go seed switchingwithin asingle row from each seed meter.
