Maize is the staple food in the southern part of Madagascar, and is mainly grown in the high plateaus of the island. Both area and production have increased since 1980. Improved varieties grown on government farms yield 4.5 t/ha, but local varieties achieve average yields of only 1 t/ha. Important results have been obtained since maize research began in 1961, in the areas of both varietal improvement and agronomic practices. After a four-year interruption, research started again in 1983, and has been oriented, in the short and medium term, to the maintenance of the main seed collection at Lake Alaotra, the reconstitution of degenerated polyhybrid lines intended for extension, the reintroduction of parental lines that had been lost, the introduction of new lines and varieties, and research on economical fertilizer practices
