Abstract
|
|
|
|
Fields experiments were conducted to investigate the effect of various tillage depth (TD) on productivity and quality of C. auriculatum Royle ex Wight from 2005 to 2006. The length of vine was elongated in lower TD treatments as 50 cm longer in 10 cm TD than 30 cm TD, and stem diameter and dry weight had increased in the lower TD. Length, width, and weight of leaves showed the quantitive growth in the lower TD treatments, but the chlorophyll content had increased in the deeper TD treatments. Root number and length had increased in the deeper TD treatments, but the root diameter and decomposed root was increased in the deeper TD. The total yield of root showed the increasing tendency in the deeper TD treatments as 6.2 ton/ha in 10 cm TD and increased as 7~9% in the 20 cm TD treatments.
