Abstract Ginseng (
Panax ginseng C.A. Meyer) is a
potential new crop for New Zealand. Under artificial shade, 1-year-old
seedlings were grown in either peat- or soil-based media for 4 years. At the
final harvest mean root fresh weight was 55 g/plant in the peat media and
40 g/plant in the soil media. Total ginsenoside % of the 5-year-old roots
was up to 6.9%. Macrochemical content (N, P, K, S, Mg, Ca) and trace element
(Mn, Zn, Cu, Fe, B) content of roots at each harvest and of the leaves at the
final harvest, were determined and compared with reported levels for
P.
ginseng and standards for
P. quinquefolius.
Botrytis cinerea
was present on plant material throughout the experiment, and there was evidence
of predation by the scarab larvae of
Costelytra novae-zealandica in the
first year. After 4 years of growth, 45% of the plants in the soil media and
63% of plants in the peat-based media survived
.
