Nitrogen is a macro essential nutrient for vegetative growth of tea plant. Nitrogen requirement on tea plantation can be fulfilled by an organic fertilizer and biofertilizer. Biofertilizer is the fertilizer with the potential to reduce 20 to 30% of an organic fertilizer used in tea plantation. The aim of the research was to test Azotobacter sp and endophytic bacteria from tea planting area (indigenous) and exogenous as biofertilizers on tea productive plants. The research was conducted in June to September, 2013. This research was done in Gambung experimental garden of Research Institute for Tea and Cinchona (RITC) using Andisol as soil type; GMB 7 clones of two years after pruning, altitude 1.283 m above sea level and slope 10%. Endophytic bacteria applied on leaves with dose 2 L/ha/application and population 2.176 1011 cfu/ml and Azotobacter sp applied on soil with dose 2 L/ha/application and population of 2.144 1011 cfu/ml. Randomized block design was used in this study with nine treatments and three replications. Micro-organisms used were Acinetobacter sp and Azotobacter sp (AK-II) as exogenous and endophtic bacteria (DtG7-5) and Azotobacter sp (RTG-1) as an indigenous. The variables analyzed were tea productivity and N absorption. The results showed that the application of Azotobacter sp and endophytic bacteria both indigenous and exogenous fluctuated to the tea productivity. Application of these micro-organisms could increase the tea productivity on water deficit month (rainfall <147 mm / month) by the average percentage 6 to 51% higher than control. The combination of indigenous Azotobacter sp with 75% dose of N, an organic fertilizer resulted in the highest increase in N absorption by 38.11%. Drought season with rainfall < 10 mm/month for more than two months disturbed the growth of tea plant, which is in August and September month but the production of shoots for indigenous Azotobacter sp with 75% dose of N organic treatment was 33.65% higher than control. These micro-organisms have a potential as nitrogen fixing bacteria to tea plant on drought season.

Key words: Exogenous, drought season, indigenous, Indonesia, nitrogen fixing bacteria, tea plant.
