2. Indonesia is the third largest rice producers after China and India
(FAO, 2008).

3. PROBLEMS INDONESIAN GOVERNMENT POLICY LEVELLING OFF PRODUCTIVITY
Prioritize high production
Increase the use of high doses of inorganic fertilizer and  ignore organic fertilizer 
INDONESIAN GOVERNMENT POLICY
Declining soil fertility and distracting soil ecosystem
  Low fertilization efficiency
Sensitive to pest & diseases
LEVELLING OFF PRODUCTIVITY

5. RESEARCH METHODS
The aims of this research is to determine the influence of the Liquid Organic Fertilizer types (LOF) on plant growth and rice yield.
The experiment was done at Bener Village, Ngrampal District, Sragen Regency, from March until November 2011.

6. RESEARCH METHODS
This research using single factor and 3 replications . It was arranged according to Randomized Completely Block Design with 5 replicates.
The treatments were: LOF“Double”, LOF“Plus”, LOF“Bacteria”, LOF“Bacteria+Plus”, and (Control, no LOF)
Control with inorganic fully, that is NPK fertilizer (450 kg/urea +200kg SP KCl)
Treatment LOF with semi organic (combining between 1.5 ton/ha organic kg NPK fertilizers)
ANOVA and DMRT at 5 % were subjected to the data

12. CONCLUSION
Additional application of LOF to NPK fertilizer resulted in the best growth and yield
Application of various LOF did not significantly different among treatments. However, the greater result found with combining LOF bacteri+Plus treatment, and than followed by LOF Plus and LOF bacteri
Additional application of LOF “Bacteria” and mixture of “Bacteria + Plus” to NPK fertilizer significantly reduced number of unproductive tillers.

14. Liquid organic fertilizer
A product from the bio-fermentation of vegetables, fruits, and animal urine, coconut water, sprout of rice, fermented with molases and useful microbes.
These microbes help to break down nutrients in the material, and making them a potentially valuable nutrient-rich organic source, such as proteins, amino acids, organic acids, major nutrients, minor nutrients, accelerating growth hormones, vitamins, and enzymes
All of which are potentially useful for the efficient growth of plants
