Traditional farmers' knowledge of Sorghum (Sorghum bicolor [Poaceae]) landrace storability in Ethiopia
Traditional knowledge of grain storage was studied on small farms in Ethiopia. Sixteen of sixty landraces of sorghum collected from small farms in Shewa and Welo regions of Ethiopia were identified by the farmers as being stored sorghum landraces. Farmers were interviewed and asked to rate the storability of these stored-sorghum landraces with respect to the major insect pest of the area, the rice weevil. A farmers' index of storability was then calculated for each landrace. The landraces were then assessed for rice weevil, Sitophilus oryzae (L.), susceptibility in standardized tests at 70% relative humidity and 27°C. The mean farmers' index for the 16 landraces was found to be inversely related with the susceptibility parameters of F1 emergence (r2=0.80), oviposition (r2 =0.76), weight loss (r2=0.88), and Dobie Index (r2=0.95). It was much less strongl
