| Abstract:
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. | |
