Onion is an important vegetable cash crop in Mauritius. It is grown mainly for the fresh market consumption and for storage. The production of onion is highly seasonal with the bulk of the crop harvested around October and November. This results in a seasonal surplus production of 1600 to 1800 tonnes annually. The aim of this project is to study the prospects of producing high quality onions in late season in the region of La Marie. If onions could be produced during that period, these can be cured and stored by farmers for the sale as from February a period when the country depends on imported onions to satisfy local requirement.
