SELECTION OF ONION CULTIVARS FOR YIELD, EARLINESS IN CROPPING, AND STORAGE POTENTIAL IN ZIMBABWE
In trials at Marondera, Zimbabwe, from 1989 to 1991 some more recently developed Grano types gave higher yields than the traditionally grown Texas Grano, were earlier maturing, and had a longer storage life at ambient temperatures in trials in a simple dry, well-ventilated store. Creole types gave lower yields while tropical cultivars imported from India had low yields and stored poorly. In a typical trial, El Ad, Galil, Texas Grano, White Creole, and Red Bombay had yields of 96, 78, 75, 36, and 28 t/ha, required 168, 175, 195, 188, and 188 days from sowing to maturity, and had 36, 57, 33, 38, and 0% of their initial weight still marketable after 189 days in store, respectively.
