Abstract
This study aims to determine the rubber grafting seedling 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, 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 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.
