Abstract Growth and tuber yield of perennial cassava crops of up to 4 years' duration were compared with those of annual crops in a subhumid subtropical environment where low winter temperature limits crop growth to 8-9 months per year. Resumption of growth by perennial cassava was rapid; sprouting occurred at many nodes in spring, and its canopy intercepted more solar radiation than did young annual crops. However, total biomass production during a season was generally slightly less than that of annual crops. After four seasons of cropping, four annual crops combined produced 49.4 t ha-1 of tuber dry weight. Corresponding yields for two 2-year crops, one annual plus one 3-year crop, and one 4-year crop, were 44.7, 40.3 and 38.1 t ha-1, respectively. The higher productivity of the annual crops was partly related to irrigation applied in the first three seasons to the annual crops. In the fourth season when no irrigation was applied to any crop, the annual increments of tuber weight in 2- and 4-year crops were similar to the tuer yield of the annual crop. It was concluded that productivity of a 2-year crop is 90-100%, and that of 3- and 4-year crops is 80-90%, that of annual cassava.
