significant difference (LSD) at 5%. The parameters measured were : buds appear
time, shoot length, number of petiole, shoot diameter and leaf area. The result
showed that provision of coconut water with 750 cc/l concentration showed the
best growth of budded stump rubber plant at parameters buds appear time, shoot
length, number of petiole and shoot diameter.
