Rubber plant (Hevea brasiliensis Muell Arg) was one of important plantation commodity as second source of foreign exchange after palm oil. The main result of rubber tree is latex as raw material for manufacture of transport equipment, medical and household appliances. This study aimed to determine the effect of the use some natural plant growth regulators on the growth of budded stump and get the best of natural plant growth regulators for budded stump rubber plant. This research has been carried out in technical services unit of Agriculture Faculty, Riau University. This research was conducted with completely randomized design (CDR) consisting of 4 treatment namely : without giving PGR, giving coconut water, green bean extract, and young bamboo extract. Each treatment was repeated 4 times with each unit consisting of 3 seedling experiment and total number of seedling was prepare 48 seedling. The data were analyzed used analysis of variance (ANOVA) and continued by least 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.

The development of the root system of plants are a reflection of the level of physical and chemical soil properties. Siltpit (rorak) is a conservation pit of a certain size and layout which systematically provide benefits for soil remediation. Empty Fruit Bunch (Tan-kos) used as an alternative of organic fertilizer and also contribute to the improvement of physical - chemical and biological properties of soil. The experiments were conducted with four treatments and 4 replications . Experiment arranged in Radomized Completely Block Design with treatment EFB applications 750 kg on the soil surface with dimension 3mx2m (T0); siltpit size 3 m x 0.66 m x 0.75 m + 750 kg EFB (T1); siltpit size 5 m x 0.6 m x 0.5 m + 750 kg EFB (T2) and siltpit size 5 m x 1 m x 0.3 m + 750 kg EFB (T3). T2 treatment gives the most influence on the increase in the CEC of 4.8 cmol / kg then T0 of 2.8 cmol / kg. Improvement P-dissolved is found in T3 4:06 ppm followed by T0 3.96 ppm, K-total increase 0.75 cmol/kg and K-available in 0.9 cmol/kg.T0 treatment effect significant difference in diameter, wet weight, dry weight and root length tertiary depth of I, II and III. While treatment pit + 750 kg EFB (T1,T2 and T3) did not significant impact and significantly influence on the treatment T2 in parameter tertiary root length of 27.93 mm in depth III.
