Investigation of Nutritional Composition and Vegetative Propagation of Two Leafy Vegetables

There is little known of the nutritional content of underutilized leafy vegetables and the efficacy of vegetative propagation of these plants. The nutrient content of Solanecio biafrae (Oliv. & Hiern) C. Jeffrey and Clerodendrum volubile P. Beauv. was measured, and the efficacy for mass vegetative propagation was determined. Protein, fat, ash, crude fiber, and carbohydrate contents of S. biafrae were either the same as or lower than previously reported. Protein, fat, ash, and crude fiber of C. volubile were lower than previously reported. The requirement for vitamin C can be met by consuming 400 g of S. biafrae or 200 g of C. volubile per day. The K and Ca contents in S. biafrae were lower and higher, respectively, than previously reported, and other elements, including Fe, were lower than previously reported. Elemental composition of C. volubile was either the same as, lower, or higher than previously reported. Tip and softwood cuttings of C. volubile were best for vegetative propagation and S. biafrae can be propagated vegetatively using two to three nodal cuttings. Both vegetables can be used for in vitro regeneration.
