Abstract
This research aims to determine the rubber grafting seediing growth response to
fertilizer compost waste rubber chips and get a dose of the best rubber grafting on
seedling growth. The research was conducted using completely randomized design
(CRD), which consists of 6 treatments and 4 replications, so the whole unit 24 unit trial.
Each experimental unit contained 2 rubber seedlings an 1 of them as a sample, K0 :
compost waste rubber chips 0 g/10 kg soil, Kl : compost waste rubber chips 25 g/10 kg
soil, K2 : compost waste rubber chips 37.5 g/10 kg soil, K3 : compost waste rubber
chips 50 g/10 kg soil, K4 : compost waste rubber chips 62.5 g/10 kg soil, K5 : compost
waste rubber chips 75 g/10 kg soil. Forwarded to the various analytical results
advanced Least Significant Difference test (LSD) at 5 % level. Based on the research
that has been done shows that administration of composted waste rubber chips rubber
grafting on nursery effect on the length of bud grafting; number of leaves and dry weight
of seedlings grafting rubber. While the use of composted waste rubber chips rubber
grafting in the nursery had no effect on girth increment bud grafting. From this study the
dose of compost waste rubber chips that gives the best results in the growth of
seedlings grafted rubber is 75 g/10 kg soil for all parameters except the parameter of
the length of bud best dose of 62.5 g/10 kg soil and 75 g/10 kg soil
