Operational parameters affecting pneumatic paddy seeds

This study was carried out to determine the critical operational parameters for pneumatic handling of MR219 paddy seeds, with emphasis to seeding of system of rice intensification (SRI) seedling tray. The relevant physical and aerodynamic properties of MR219 seeds were studied. Twenty nozzle design...
