Breaking Seed Dormancy In Bambara Nut (Vigna Subterranea (L) Verdc)

ABSTRACT

 

A study was carried out to investigate the effects of sulphuric acid, hot water and soaking of seed in water treatments on the germination of Bambara nut (V. subterranea) seeds were planted in poly pots for germination. 40 seeds of Vigna subterranea (one per poly pot) with ten replicates each were used. The highest germination was recorded in seeds soaked in water for 24 hours. Germination was observed to be low or slow in untreated (control) seeds. While there was poor or no response in growth of seed treated with hot water of about 100oC for 2 minutes and that of the seeds soaked in sulphuric acid of 50% Concentration for 60 minutes. These methods could be applied to desirable promotes seed germination in Bambara nut.
