Abstract
The objective of this study was to investigate the germination capacity, field emergence and quality attributes of seed stored under a variety of storage types and used by farmers in the rain fed sorghum producing areas of Sudan as a seed source. Seeds were obtained from a conventional silo with limited controlled conditions, a brick wall warehouse, and a corrugated iron warehouse ( Where seeds were stored for one and two years); a modern silo with controlled conditions and underground pits (Where seeds were stored for one year), and newly harvested seed. The following tests were carried out: 100-seed weight, standard germination test, purity test, viability (Tetrazolium) test, oil and protein content, percentage of seeds in different classes of ungerminated seeds, percentage of abnormal seedlings and field emergence. Seeds stored in brick wall warehouse and traditional silo for one year showed significantly lower values of the tested attributes compared to seeds stored in the modern silo and newly harvested seeds. Storing the seeds in these two types of storage for a further year resulted in further significant decreases in the tested characters. Seeds stored in corrugated iron warehouse for one year had significantly lower test results compared to seeds stored in the traditional silo and brick wall warehouse. Storing seeds for a further year in a corrugated iron warehouse resulted in the loss of 60% of their viability and germination capacity. Also, the result revealed that seeds stored in underground pits (matameer) for one year lost most of their germination ability (< 0.11) and their viability (< 0.17) and may contain up to 30% inert matter and other seeds. Seeds stored in the modern silo had protein and oil contents similar to those of the newly harvested seeds, but significantly higher than all other types of storage. The significance of these results was discussed.
