The performance of pneumatic nursery protray seeder was evaluated in terms of miss seeding, single seeding, multiple seeding, seeding efficiency, and seeder output for different levels of mouthpiece diameter and suction pressure for tomato (Solanum lycopersicum L.). With a mouthpiece diameter of 0.84 mm and suction pressure of 6.2 kPa, it was found that 59.25% of single seeding, 97.69% seeding efficiency, and a seeder output of 67 cells/min were suitable for tomato seedlings. The pneumatic protray seeder resulted in a saving of 15.04 per 1000 cells sown compared to manual seeding. The payback period was 104.7 hours (3.58% of the expected life of pneumatic protray seeder).
