<p>This study was set to investigate the germinability and storability of the newly released cowpea genotypes and secondly the influence of different storage materials under ambient storage condition on seed vigour and germination over time. The experiment was laid in a Split-split plot design with four replicates. The main plot was duration (0, 30, 60 and 90 days), while Storage material (polyethylene bag, cotton bag and glass container) was sub plot and the four cowpea genotypes were sub-sub plot. Results from the study showed that irrespective of the cowpea genotypes and storage material used, percentage vigour and germination were significantly affected with time in storage. Seeds stored in cotton bags had the least percentage vigour (57%) and germination (65%) while the highest was recorded for seeds stored in air-tight glass containers. Among all the cowpea genotypes studied, Hewale was found to have poor storage abilities. For better storage of cowpea seeds for a period exceeding 3 months, it is preferable to use glass containers or black polyethylene bags even under ambient condition to maintain seed vigour and germinability.</p>
