“…Effect of endophite bacteria on length of rice plant canopy showed that almost all isolates tested were able to stimulate the growth of rice plant canopy compared to control (Munif et al, 2016). In research (Khaeruni et al, 2020) treatment of endophite bacterial isolates significantly affected height of cocoa plants and was significantly different compared to controls. Arabidopsis plants treated with Bacillus aryabhattai showed increased growth compared to control plants.…”

Tea (Camellia sinensis L), is a popular agricultural product enjoyed by people around the world. Bio-fertilizers that use bacteria found in soil called endophytes, have proven effective for increasing growth and plant productivity. Endophite bacteria can also produce growth hormones such as auxins, ethylene, and cytokinins. This research aims to determine the effectiveness of auxin-producing endophytic bacterial microcapsules on tea growth. The research design used was a completely randomized design (CRD), 16 treatments with 2 replications. The first factor was immersion of endophite bacterial suspension consisting of S0 = 0 hours; S1 = 24 hours; S2 = 36 hours and S3 = 48 hours and the second factor was the addition of microcapsules consisting of I0 = 0 gr; I1 = 5 gr; I2 = 10 gr; I3 = 15 gr. Isolation from tea roots and stems obtained 6 isolates of endophite bacteria. Auxin test showed that the six isolates were able to produce auxin. Observation of plant height showed that the best treatment was in treatment I3 (17.04 cm). Observation of leaves amount was in treatment I3 (6.88 strands). For the leaf area parameter, the highest number was in the S1 treatment (22.8 cm2). For stem diameter parameter, highest data was in treatment I2 (1.69 mm). The test results showed that the application of suspension and endophite bacteria microcapsules significantly increased the growth of tea.

Rubber plant (Hevea brasiliensis Muell.Arg) is the main commodity of plantations, some of whose products are exported and some to meet domestic needs as raw materials for industrial purposes. Purpose on research diversity and crateristics of endophytic bacteria producing hormone IAA from rubber plants. Then the effectiveness treatment of microgranules addition and immersion of endophite bacterial suspension and rubber seed soaking suspension to spur the growth of rubber plants. This research was conducted using the factorial CRD (Completely Randomized Design) method consisting of 16 treatments with 2 replications. The first factor was immersion of endophite bacterial suspension consisting of R0 = 0 hours; R1 = 12 hours; R2 = 24 hours and R3 = 36 hours and the second factor was the addition of microgranules consisting of J0 = 0 gr; J1 = 10 gr; J2 = 15 gr; J3 = 20 gr. The results of this study showed that the results on the isolation of endophite bacteria from the tea plant from the roots and stems of the tea plant yielded 3 isolates from plant roots and 2 isolates from plant stems. For IAA levels, the five isolates were positive. The use of endophytic bacteria as an alternative biofertilizer has a significant effect on the parameters observed

“…Based on results test there are 5 isolation of bacteria derived from roots and stems of cocoa plants, produced auxin hormones. Previous researchers have proven that physiological improvement of plant seeds and plant growth retardation by addition of endophytic bacteria or other microbial groups were related to the ability of microbes to increase nitrogen fixation, auxin production, and phosphate dissolving ability as per research (Khaeruni et al, 2020). Ability of microbes produced auxin was also influenced by type of microorganism species.…”

Fertilization is an important process in the growth of cocoa (Theobroma cacao L). Fertilizing cocoa usually used inorganic fertilizers. Using of inorganic fertilizers continuously could degrading soil fertility. One of the efforts to replace inorganic fertilizers was using endophytic bacteria as biofertilizers. Some endophytic bacteria are abundant in healthy plant tissues. The aim of this research was to obtain endophytic auxin-producing bacteria in cocoa plants and determine the effect of seed immersion and microcapsules addition of endophytic bacteria on cocoa plant growth. The research design used was Complete Randomized Design (CRD), 16 treatments and 3 replications. The first factor was immersion of cocoa seed using endophytic bacteria suspension consisting of S0= 0 hours; S1= 5 hours; S2= 6 hours and S3= 7 hours and the second factor was microcapsules addition consisting of B0= 0 gr; B1= 5 gr; B2= 10 gr; B3= 15 gr. Isolation from the roots and stems of cocoa obtained 5 isolates endophyte bacteria. Auxin assays showed that five isolates were able to produce auxin. Observations on plant height showed the best treatment was treatment B1 (32.49 cm). Observation of total leaves showed S3 treatment was the highest data (11.83 strands). Observation rod diameter parameter, highest data was S3 treatment (4.01 mm). For leaf area parameter, highest value was B1 treatment (66.64 cm2). For wet weight parameter, highest data was S3 treatment (18.41 g). Root length parameter, highest data was B3 treatment (15.78 cm). Test results showed that the application of suspension and microcapsules of endophytic bacteria significantly increased growth of cocoa.
