摘要

Sweetpotato is an important tropical tuber crop cultivated mostly under temperate and mild tropical climatic conditions. Its tubers are rich in carbohydrate and some are rich in carotene. The crop is vegetatively propagated through vines. The shoot emerging from the planted vine which grows rapidly for two months and later the growth rate slows down. Within three weeks after planting vines, tubers are formed which later develops into tuber. Soil nutrients such as nitrogen and potassium influence growth and yield of sweetpotato. Water deficit stress and high temperature are major abiotic stresses that affect sweetpotato growth and yield. Sweetpotato can tolerate low level of shade. This chapter presents recent research work done on physiological aspects that influence the growth and productivity of sweetpotato.
