The presentation is on the results of trials implemented under Africa RISING project on onions. This is one of the 3 – 4 vegetables species being worked on as vegetable trials.
 
Background
 
Onion plays a key role as source of nutrients and income for people in sub-Saharan Africa but few high-yielding varieties are available to farmers.  World top producers of onions are china, India, USA, Iran and Russia; world top exporters are Netherlands, India, Mexico, China, Egypt, USA, and Spain; and world top importers are USA, Germany, UK, Russia, Malaysia, Japan, etc. The production, growing areas and yield of onions vary according to countries and how intensive the production system is. The presentation reveals the onion mean yield (t/h) globally from 2005 – 2012. The mean yield of onion is very high above 40t/h for countries like China, Netherlands, Spain and USA; whereas yield is about 20t/h for countries like Mali, Senegal, Niger in West Africa. This shows that the difference is very high. The presentation also depicts imported and exported onions in metric tons in different countries from 2012 – 2016. It is to be noted that India is the top exporter of onions globally, followed by Netherlands and China. Looking at some West African countries such as Niger and Mali, the exportation of onion is very low as compared to the other countries. Importation of onion is even higher in Mali than the exportation.
