The shape and size of seed plate orifice were decided on the basis of the dimensions
of the different seeds. For all the seeds, the shape of the seed plate orifice showed its effect upon
the planting accuracy. For cotton, groundnut and sesame seeds, best results were found with
elliptical shaped orifice, with longer and shorter axis (5, 4.50), (3, 2.50) and (1.50, 1) mm, respectively.
Whereas, for okra seed, the optimum seed plate orifice shape was circular with 3 mm diameter. For
positive release of the sesame seed, air velocity of 3 m/s through chamber open to atmosphere
showed best results.
