Irrigation System for a Roller-Type Onion Pot Seeding Machine

An irrigation system for roller-type onion pot-seeding machines was developed. It is a drip-type and can be installed easily to the existing roller-type onion pot-seeding machines by its modular design. The components were selected to satisfy the required irrigation conditions for onion seeding. The operating condition was determined from a factorial experiment. A verification test was conducted and the result showed that the irrigation system developed made a significant positive contribution to the growth of onion seedlings.
