Azotobacter chroococcum based biofertilizers have been widely used in the production of environmentally agriculture. For commercial scale, cheap growth media for Azotobcter inoculant  will affect the quality and price of liquid biofertilizer. Growth medium should support cell proliferation as well as its  nitrogen fixation and phytohormone production.  The objective of this study was to determine whether  liquid organic fertilizer (LOF) containing low N can be used as a medium for scaling up  A. chroococcum inoculant without lowering the survival of bacteria and its activity in N2 fixation and phytohormones production. LOF generally contains a complete nutrient although in a small quantities. Experiment was set up in completely randomized design which tested two types of commercial LOF. The results showed that both of  LOF were only able to support cell growth up to 72 hours and at 96 hours cell viability began to decline compared to the control medium,  free-N Ashby. At 72 hour total N and cytokinin  concentration in LOF was lower than those in Ashby media. This study revealed  that LOF  could be used as A. chroococcum growth media, but without optimization of its composition, cell density and cytokinin content would be lower than those of inoculant  in Ashby Media.

[EFFECT OF CONCENTRATION AND APPLICATION TIME OF ORGANIC FERTILIZER LIQUID BANANA PEELS ON GROWTH AND YIELD OF JAVA TEA (Orthosiphon aristatus)]. Java tea are medicinal plants that have many health benefits but java tea production is very low. Efforts are made to increase the growth and yield of java tea, namely the use of liquid organic fertilizer (LOF) banana peels. This study aims to obtain concentration, application time of LOF banana peels, and interactions between the two that produce high growth and yield of java tea. The study was conducted from November 2018 to February 2019 in the city of Bengkulu. The experiments were arranged based on a completely randomized design factorial pattern. The first factor is the LOF concentration of banana peels 25 mL/L, 50 mL/L, 75 mL/L, and 100 mL/L. The second factor is the time of LOF application which consists of 1 week application, 2 weeks application, and 3 weeks application. The results showed that independently giving concentration and application time and interaction did not significantly influence the variable thickness of leaves, total leaf area, shoot length, number of leaves, fresh plant weight, root length, and dry plant weight.
