Abstract:Small scale yield studies, germination tests, controlled plantings, and packaging often require the counting of large numbers of seeds. The system described in this paper uses a photosensitive detector and a vacuum pickup to count individual seeds and gives a direct digital readout. The count rate is limited only by how quickly the seeds can be fed through the counting tube without clogging it or having them touch each other. This greatly speeds seed counting, eliminates operator error, and reduces operator fa… Show more

New light reflecting optoelectronic fields counter capable of detecting and counting free falling object with equivalent length/diameter ≥0.5mm in seeder delivering tube was developed and tested to evaluate seeding rate.
