Relationship between the attitudinal limit of cassava and soil temperature in Papua New Guinea
, and
Observations on the upper attitudinal limit of cassava at various locations in Papua New Guinea (PNG) gave a mean of 1800 m. The mean of a set of soil temperature measurements at one location at this altitude was 17.9ºC. Experimental work in Queensland has indicated that a mean soil temperature of 18°C is the lowest temperature for satisfactory cassava establishment. It is suggested that the upper attitudinal limit of cassava in PNG is related to soil temperature.
