[Effects of seeding and sowing methods on the yields of root tubers of Curcuma longa].

OBJECTIVE: To provide a scientific basis for standardizing the cultivation method for Curcuma longa. METHOD: Plant heights and seeding numbers were sampled periodically, the plot yields were counted a tharvested. RESULT: The effects of seeding method on yields, plant height and number were significant. The effects of different sowing ways on the yields were very little. CONCLUSION: The hole seeding method using mother tuber or blastostyle bearing three to four knots was shown to be the best may, worthy to be widely applied in production.
