摘要

Production under irrigation and the highly-favoured upland systems currently accounts for approximately 70 percent of all rice production in Latin American countries. Production has increased from 16 million tonnes of paddy in 1980 to 26 million tonnes in 2005. However, farmers' yields remain far below the potential of the available varieties. This yield gap is the result of numerous deficiencies, in particular inadequate crop nutrition practices and their inefficient use (rice requires large amountsof nitrogen and potassium). Two countries are representative of the overall situation.
