Parameters observed were shoot growth time, shoot length, shoot diameter, number of leaves, shoot dry weight. Giving the concentration of 75% young coconut water and 2% shallot extract gave the best results on the growth of shoot length, number of leavers, bud diameter and ory weight of shoots from the stum rubber sleeping eyes.Giving 75% of young coconut water (containing cytokinin) and 2% onion extract (containing auxin) increases shoot length by 44.17 cm compared to without treatment of 10.33 cm Keywords:young coconut water,red onion extract,rubber sleeping eye stump ]]>
