Abstract:
This research aims to determine the rubber grafting seedling growth rcsponse 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, K1 : 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 Significanl 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 weigtrt of seedlings grafting rubber. While the use of cornposted 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.
