A Kernel Based Rejection Method for Supervised Classification

Apparatus for automatically dropping plant seedlings at measured intervals into a furrow behind a plow point which digs the furrow as the apparatus is moved over a ground surface. The seedlings are contained in a multiple compartment tray which is automatically advanced as each plant is discharged, so as to position the next plant for discharge. The tray contains multiple rows of seedling compartments, and as each row is exhausted of its contained seedlings, the tray is automatically advanced to position another row of compartments for discharge of the seedlings contained therein.
