Tea was planting an upland area with Andisol as the dominant soil ordo. Andisol has a special characteristic i.e. low soil pH and it has more mineral that causing low of soil phos-phate soluble, especially for tea plants, there-fore the rule of solubilizing phosphate bacteria will be needed. Laboratory scale experiments were conducted to study the capability activities of some solubilizing phosphate bacterias name-ly Pseudomonas cepaceae, P. malei, Bacillus mycoides, and B. subtilis. The experiment was arranged in Completely Randomized Design with six treatments and four replications. The result on statistical analysis shown that there were no significant differences in increasing of the soil phosphate soluble. Nevertheless, the treatment D (Bacillus mycoides) produced the highest soil phosphate soluble. The capability of bacteria to increase soil phosphate soluble was depended on its habitat, especially soil pH. Even all of the isolates were the superior solubilizing phosphate bacterias in agricultural food plants with neutral soil pH, but they have not significantly different on Andisol. There-fore, the using of indigenous isolates on tea plant areas was suggested.

Among problems encountered in the availability of quality seedlings in nurseries is a low percentage of seedlings ready to plant. The seedling will remain stunted if no treatment is provided. Therefore, there must be some treat-ments carry in the nursery, as increase seedling ready to plant. One of the problems causing lack of good seedling growth is less than optimal growth and the role of the root, thus, the increase in the growth of the tea plant seeds can be cultivated among others through im-proved root system. The objective of this re-search was to determine the effect arbuscular mycorrhizal fungi (AMF) and plant growth regulator (PGR) against the percentage of root seedlings were ready to plant. Root growth can be accelerated by the application of PGR roots, ability to function and role of the roots can be improved by application of biological fertilizers such as AMF. The experimental design used was a randomized block design combined con-centration of PGR roots consisting of Z0: 0 mg/mL; Z1: 25 mg/mL; Z2: 50 mg/mL; Z3: 75 mg/mL with a dose of FMA consisting of: F0: 0 g FMA/plant; F1: 5,0 g FMA/plant; F2: 7,5 g FMA/plant and F3: 10,0 g FMA/plant. The experiment was conducted at the Gambung Experimental Station at the Research Institute for Tea and Cinchona, Bandung, West Java, at a height of Â± 1.350 m above sea level with the type of Andisols. Rainfall including B-type according to the classification of Schmidt and Fergusson (1951). The experiments resulted in the conclusion FMA 7,5 g dose combination treatment plants PGR-1 with a concentration of 25 mg/mL root, generating growth in both the percentage of root infection, seedling height, the number of leaves, and the amount of leaf chlorophyll and the percentage of tea planting material. The treatment resulted in a 35% increase in plant height, a number of leaves nearly 68% and the amount of chlorophyll is 83% higher compared to treatment without the FMA and without PGR. The percentage of 12 months old planting material with treatment reached 78,11% higher than the treatment without AMF and PGR which reached 49,28%.
