Root starch content was consistently higher in the variety Black Twig than in the variety C5 and was always higher at 1 × 1 m than at 3 × 3 m plant spacing in both varieties throughout the sampling period; 36 to 68 weeks of age. C5 produced greater fresh root yields than Black Twig at both planting densities. Starch yields per hectare were greater from C5 in the ninth month after planting, but after this they were similar for both varieties. No marked peak or consistent decline in root starch content associated with increasing age was observed. It is suggested that variations in root starch content could be influenced by climatic factors, particularly rainfall, and soil moisture. Long‐term research in this area is required.
