Abstract
This study was conducted to seek optimum sowing time and pinching height for tender shoots production of moloheiya (Corchorus olitorius L.), which is a subtropical leaf vegetables, under an unheated greenhouse in the south of Korea. Seeds of moloheiya did not germinate at all at $10^{\circ}C$, but germinated well at $18{\sim}30^{\circ}C$ with 95.5~98.5% germination rate. Germination rate was 75.0% at $15^{\circ}C$, but germination speed was very low. The pods of moloheiya sown before April 28 was matured after late-August, but those sown after May 7 was not matured in that year. In tender shoot production and harvest frequency, treatment sown on April 14 was most plentiful among sowing time treatments, and showed marketable yield increase by 14~42% compared to other sowing times. Mean-while, pinching at 100cm high from soil surface was more effective than other heights for increment of branches and tender shoot. All above suggest that it was suitable to sow seed on mid-April and to pinch at 100cm high from soil surface for increment of tender shoots in the south of Korea.
