Tuber crops are the most important land-grown food crops after cereals and grain legumes. They are either the
staple or subsidiary food for about one-fifth of the human population, mostly in the developing countries of the
tropics. Tropical tuber crops like cassava (Manihot esculenta Crantz.), sweet potato [Ipomoea batatas (L.) Lam.],
yams (Discorea spp.), aroids and minor tubers deserve special recognition owing to their higher biological efficiency
(250 kcal/ha/day), ability to sustain under marginal environmental conditions, less incidence of insect-pests
and diseases, high starch content (15–35%) and their excellent physico-chemical and biochemical properties in
the preparation of several value-added products. Though tuber crops especially cassava grow under marginally
fertile soil conditions, our experience under a long-term fertilizer experiment revealed their very high and positive
response to manures and fertilizers. This review encompasses the research work undertaken in the soil fertility
and nutrient management of tropical tuber crops covering aspects on nutrient uptake/ utilization, fertilizer-cummanurial
recommendations, critical nutrient concentrations, nutritional disorders, and their correction
