This study aimed to determine the effect of storage duration on sorghum seed quality, specifically focusing on weight loss and storage pest infestation, under laboratory conditions. Eight different sorghum cultivars (Kawali, Numbu, Suri 4, Super 1, Soper 6, Bioguma 1, Bioguma 2 and Bioguma 3) were tested, each with an initial moisture content of 12%. The experiment used a completely randomised design with five replications for each cultivar. Observations for weight loss and seed damage were performed at 1, 2 and 3 months of storage. Proximate analysis was also conducted to determine the ash, protein, fat and fibre content of the sorghum cultivars. All tested sorghum cultivars demonstrated slightly moderate tolerance for up to 3 months of storage, although some experienced increased weight loss during this period. The pest species responsible for damage to stored sorghum seeds was identified as Sitophilus oryzae. Significant correlations were found between weight loss and damaged seeds, damaged seeds and crude fibre content, weight loss and crude fat content, weight loss and crude fibre content, and ash and crude protein content. This study shows that while sorghum cultivars generally exhibit slightly moderate tolerance for up to 3 months of storage, they are susceptible to damage from S. oryzae. The research also identified key compositional factors, such as fibre and fat content, that influence seed damage and weight loss during storage.
