Abstract
Burdock (Arctium lappa L.) is a medicinal plant, highly rich in phytochemicals which
contribute towards its antioxidant properties and treatment of chronic diseases. It is also
consumed as a vegetable in some regions of the world because of its high nutritive
value. Currently, the plant material is imported for its medicinal purposes by herbal
practitioners and pharmaceutical industries in the different countries of the world,
including South Africa. However, the cultivation of this plant is lacking in South Africa
and Africa as a whole. In order to achieve consistent supply of quality products and
eliminate batch-to-batch variability of plant materials, a factorial experiment was
conducted on Takinogawa long cultivar with eight treatments (T1=N423P210K315,
T2=N423P280k315, T3=N635P210K315, T4=N635P280K315, T5=N846P210K315, T6=N846P280K315,
T7=N1058P210K315 andT8=N1058P280K315 Kg/ha) and five collection time of data laid out
in a completely randomized design replicated five times under 40% shade net. Fertilizer
treatments were split into two equal doses at seedling transplant and four weeks after
transplant. Data on morphological characteristics and yield were collected and analyzed
using SAS software. There was a significant (P<0.05) difference across fertilizer
treatments on morphological characteristics as well as the interactions between
treatments and time of data collection. Significant differences (P<0.05) were also
recorded on the yield parameters. Two treatments (N635P210 K315 and
N635P280K315Kg/ha) significantly outperformed the other treatments. However, more
research needs to be done on the enhancement of secondary metabolites of interest for
the sustainable supply of quality plant materials for herbal practitioners and
pharmaceutical industries.
