Abstract

A new high‐yielding upland rice variety known as New Rice for Africa (NERICA) has been widely recognized as a promising technology for addressing the food shortage in sub‐Saharan Africa. However, there has been no on‐farm yield data to support this optimism. The present study attempts to assess the actual and potential yield of NERICA in Uganda where it has been introduced recently. We found that NERICA's yield is higher (2.5 tons) for farmers who had rice‐growing experience than those who had no previous experience (1.7 tons). These findings strongly indicate that strengthening training, extension, and other supporting systems is the key to the success of the “NERICA revolution” in this country.
