Fourteen different types of tubers collected from Joida taluk of Uttara Kannda district exhibited significant differences in the nutrient composition. The protein (4.14-8.73 %), fat (0.07-1.10 %), dietary fibre (4.80-12.13 %), total sugar (1.31-11.16 %), reducing sugar (0.32-4.28 %), ascorbic acid (1.65-8.44 %), starch (33.97-69.18 %), and energy (349-368 kcal) values varied. The range of macro mineral- calcium (447.00-1041.50 mg), phosphorus (112.95-398.66 mg), magnesium (178.00-417.50 mg) and micro mineral- iron (0.45-3.31 mg), zinc (0.56-6.93 mg) per 100 g of sample varied and significant difference was found between the tubers. As the tubers were genetically not identical, these wide variations in the nutrient composition were naturally expected. The tubers being the good source of nutrients, it can be well replaced with other food ingredients in the regular diet.
