    This research aim to know giving influence of compost LCC Mucunabracteata( MB) and NPK tablet at growh of seed palm and best treatment at growth of seed palm in main mxsery bed. This treatment in executing experimentally with by using Completely randomized design ( RAL) which consist of 5 treatment and 3 restating, so that entirely 15 attempt units. Every attempt unit consisted of 3 polybag crop and 2 between it as sample, P0: Without fertilizer, P1: compost LCC MB 25 gl10 soil;land;ground kg + NPI( I tablet, P2: compost LCC MB 50 g/10 soil;land;ground kg +NPK 2 tablet, P3: compost LCC MB 75 g/10 soil;land;ground kg + NPK 3 tablet, P4:compost LCC MB 100 g/10 soil;land;ground kg + NPK 4 tablet. Analysis of variance result showing existence of reality difference, continued with tested to be continuation with deep experiment Duncans New Multiple Range Test ( DNMRT) at level 5 %. Based on research result which has been done indicates that giving of compost LCC + NPK TABLET at nursery bed of palm in main nursery bed had an effect on to high increase, increase of number of leaves, cusp diameter, root volume, dry weight and seed root coronet ratio. From this research giving best influence at dose 100 g/10 soil;land;ground kg + 4 tablet.

    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.
