Abstract

An experiment was conducted at the Forage Laboratory of Feeds and Nutrition Research Programme, National Animal Production Research Institute, Shika-Zaria to investigate the effect of hot and cold water treatment durations on seeds germination and emergence of Tephrosia seeds. A total of 825 clean healthy seeds of T. bracteolata were divided into 11 treatments durations using hot water at 600C and cold water at room temperature for 0, 2, 4, 6, 8, 10 minutes and 2, 4, 6, 8 and 10 hours, respectively. The untreated served as the control (0). The treatments were replicated three times and arranged in a completely randomized design (CRD). Hot and cold water treatment durations had significant (P<0.05) influence on percentage seed germination, emergence dormancy and seedling vigour. There was no significant (P>0.05) effect on the seedling length in hot water treatments and the control. Treatments of Tephrosia bracteolata in hot and cold water proved very effective for seed germination and enhancement, dormancy alleviation and increased seedling vigour. The highest value of 80.33% was obtained for hot water treatment duration at 8 minutes and 72.00% for cold water at 10 hours for percentage germination obtained. Seedling vigour index (1041.33) was better at 8 minutes hot water treatment than (986.0) at 10 hours treatment in cold water. There was no significant interactions between hot and cold water treatment except at emergence of the seeds. From the research conducted, treatment of T. bracteolata seeds in hot water up to 8 minutes optimum and cold water up to 10 hours soaking durations is recommended to farmers and researchers for enhanced seed germination and optimum potential seedling establishment.
