Onions are vegetables that contain plant potent compounds that have been shown to promote human health in several ways. The biological productivity in terms of growth, yield and bulb qualities have been shown to vary among varietal type. Hence a field experiment was carried out to compare the growth, yield and bulb quality of two onions varieties (Allium cepa L. cv Red and White creoles). The field layout followed complete randomized block design with three replications. The data on biological yield and biochemical parameters were subjected to student t-test at 0.05 level of significance. The results showed that White creole had higher growth than Red creole. However significantly (p≤ 0.05) higher bulb yield was recorded in Red creole (1126kg/ha) compared to White creole (600kg/ha).
