The results showed that concentrations of the extracts of onion geve significant effect against the number of roots of mucuna age 60 HST,significant effect against shoot on 40 and 60 after day plant  andnot significant against the number of shoots. The best of growth cuttingfound at 15 ml concentration  of onion extract per liter of water. The plant medium effected was  not significant on  high shoots towards 40 and 60 after day plant, amount of mucuna shoots and number of roots  on 60 after day plant. Therewas asignificant interaction between extract of onions and plant media againstthe root length of mucuna. The best length of root found at concentrations of 10 ml of onion extract per liter water,plant media with 2:1(soil: manure). Keywords : Onion extract, vegetative, medium, mucuna
