Tuber crops are the third most important food crops, after cereals and grain legumes. The important tropical tuber crops are cassava, sweet potato, yams, aroids and a few minor tuber crops. There is a wide difference between potential yield and actual yield of tuber crops obtained in farmers’ fields which may be due to genetic as well as soil and environmental factors. Photoperiod, light intensity, temperature and moisture availability are the most important abiotic factors governing the onset of tuber differentiation and rate of tuber bulking. It is necessary to understand the effect of abiotic stress factors on growth and productivity of tuber crops to identify/develop crops/varieties and to evolve appropriate management practices to sustain productivity especially in the context of climate change. Hence, the influence of abiotic stress factors such as solar radiation extremes, temperature extremes, drought, flooding/waterlogging, elevated CO2 concentration and salinity on the tropical tuber crops is dealt with in this chapter.
