Challenges Revolutionary Low Cost is required

• A conceptual breakthrough is requested Fresh, Processed (paste etc.) • Information exchange and discussion among different industries are most

important. • A hardware only solution is inefficient (The combination of breeding

(cultivar) and cultivation techniques is important.) • Long term prospect: Overseas development • Short term prospect: Large-Scale facilities (Plant factory special zones) • Introduction of IT, downsizing and reducing cost of control systems • Reduce labor cost and product cost ( automation, development of labor

saving devices)

Supplying a limited amount of

Nitrogen per plant to control LAI

The nutrient solution can be

uniformly supplied to all the plants.

Supplying sufficient oxygen for a

root can be continued.
