Nonsymbiotic N-fixing bacteria including rhizobacteria play a role in providing N elements for plants. Some types of rhizobacteria can function as Ryzobacteria Plant Growth Promoting Rhizobacteria (PGPR). Indigenous rhizobacteria are more adaptive and efficient because rhizobacteria colonies develop well in the soil in accordance with their habitat, so N fixation is greater. Pot experiments were carried out using a Completely Randomized Design with a combination of 3 types of indigenous N fixing isolates, namely: I1: Isolate A1.bk, I2: Isolate A2.bb.p, I3: Isolate A3.tt.k, I4: Isolate (Isolate A 1.bk + A 2.bb.p), I5: Isolate (Isolate A 1.bk + A3.tt.k), I6: Isolate (A 2.bb.p + A3.tt.k), I7: Isolate (A1.bk + A2.bb.p + A3.tt.k), repeat 3 times with 21 pots. Analysis of the quality of the... initial and final rice field research. Azotobacter single isolate for fixing N is very low so that the protection of vegetative and generative growth is not significantly different, except single isolate I3 for observation of the number of filled grains and production ha-1 shows significant differences with other single isolates. The response of Azotobacter isolates to the growth and rice production of the SRI method was determined by the type and combination of indigenous Azotobacter isolates. Azotobacter indigenous isolates are stronger giving high yields for vegetative, generative growth and soil quality. The results of rice plants showed that the combination isolate I4 (A1.b.k + A2.bb.p) was the best isolate for all observations of vegetative and generative growth parameters. The stronger the ability of indigenous Azotobacter isolates to live the better N fixation and soil nutrient content. The results of the analysis of soil nutrients at the end of the study there is an increase in soil nutrients in pH, N, P, K, base saturation, which shows the characteristics of moderate soil fertility.
