Seed quality is fundamental to agricultural productivity and sustainability. Sorghum, as a versatile crop with a wide range of applications, requires high-quality seeds for optimal production. Understanding the seed storage condition, storage period and packaging materials on seed physiological quality is a basis of field crop establishment. This study aimed to evaluate the impact of packaging materials, storage conditions, and storage periods on the physiological quality of sorghum seedlings. One hundred grams of sorghum seed from 5.4 kg of cleaned sorghum seeds were packed in polyethylene bags, polypropylene bags, and aluminium foil. The seeds in packaging materials were stored at 3 different temperatures for 2, 4, and 6 months and the sample of ten grams was taken every 2 months of storage time for germination test. The data on normal seedlings, abnormal seedlings lengths, and seedling dry weight were recorded. The results showed that polyethylene bags at 10°C and 2 months of storage preserved seedling physiological quality more than aluminium foil and polypropylene bags. This may be attributed to the impervious properties of polyethylene hence preventing oxidative reactions and seed deterioration. To guarantee the successful field establishment and strong plant stand of sorghum crops, findings advise seed producers and farmers regarding appropriate seed storage procedures.
