Low yield and poor quality of onions produced from the Sudan Savannah Agro-ecological Zone of Ghana among other factors attributed to lack of appropriate cultivars for cultivation, poor knowledge of plant spacing and storability. These factors have the potential of lowering income levels of farmers and wasting precious agriculture land. Field and storage experiments were conducted at Bawku in the Upper East Region of Ghana from 2015 to 2016 to investigate the response of cultivar and spacing on growth as well as yield and shelf-life of onions.
