Table 1.

Comparison of C₄ crop water use and yield. Global average and Least Developed Countries yield data (Tonnes per Hectare) are adapted from the FAOstat database for 2019 crop yields (Food and Agriculture Organization of the United Nations, 2019). The minimum and maximum yield range (Tonnes per Hectare), growing season water requirements (mm), as well as the growing season length for each crop are adapted from the Useful Tropical Plants Database (Fern and Fern, 2014)

Crop	Scientific Name	Water Requirement (mm)	Growing Season Length (months)	Global Average Yield (T·H−1)	Least Developed Countries Yield (T·H−1)	Minimum Yield Range (T·H−1)	Maximum Yield Range (T·H−1)
Maize	Zea mays	500–750	4–5	5.8	1.95	1	20
Sugarcane	Saccharum officinarum	1,200–2,700	11–18	72.8	57.74	50	150
Sorghum	Sorghum bicolor	450–650	3–4	1.45	0.89	2	6
Teff	Eragrostis tef	300	2–5	0.89^a	0.67^a	0.2	4.5
Finger millet	Eleusine coracana	350	3–6	0.89^a	0.67^a	0.25	5
Proso millet	Panicum miliaceum	200–300	2–3	0.89^a	0.67^a	0.45	2
Pearl millet	Cenchrus americanus	350	2–3	0.89^a	0.67^a	0.25	8
