Abstract

This study aimed to develop a seeder for sowing large seeds such as those of fruit vegetables used as rootstocks in grafting. It investigated how the nozzle diameter and the nozzle's vacuum pressure affected the seeding performance. This study found that a nozzle diameter of 1.5 mm was capable of sowing most of the seed sizes used in this study. The highest seeding rates for 'Chambak', 'Tuktozwa', and 'Hukjong' were $97.6\%$, $98.8\%$, and $97.6\%$, respectively. Lineup status after sowing was good. The working performance was 75.6 sheets/hr. An average seeding rate of 1 grain was $97.8\%$.
