In Indonesia, annual growth rates for cassava production and yield from 1961 to 2000 were 0.81% and 1.35%, respectively. However, the harvested area decreased at an average annual rate of 0.61%. The average yield of about 12 tonnes of fresh roots/ha is much below the potential yield of 20 to 40 t...
