Example calculation potential yield
Climatical data: El Kharj-Saudi Arabia-24 °C N.Lat.
Calculation potential yield: Spring crop El Kharj
Total plant dry weight: 12319 kg/ha
Haulm and roots (25%): 3080
Total tuber dry weight: 9239 kg/ha
The calculated potential total tuber fresh weight: 100/20 x 9239 = 46.2 tonnes/ha.
The actual yield of a specific crop in the same period was 25 tonnes/ha.
