Abstract
The research aims were to analyses the effect of bacterial mixture of Azotobacter and Azospirrilum on the ^nitrogen content and harvest date of upland red rice. This research was conducted in Agriculture Farm of Agriculture Faculty in Halu Oleo University. The research arranges in a split plot design. The bacterial mixture dosage as main plot and different of cultivar as sub plot. The bacterial mixture dosage were b0 = without application bacterial mixture, b1 = Bacterial combination mixture of Azotobacter 2.5 L ha-1 + Azospirillum 2.5 L ha-1 and b2 = Bacterial combination mixture of Azotobacter 5.0 L ha-1 + Azospirillum 5.0 L ha-1. The cultivar tested were (v1) = Labandiri, (v2) = Jangkobembe, (v3) = Ranggohitam and (v4) = Paedara. This research showed that application of bacterial mixture had given the following results that has no significant effect on nitrogen leaf content, but has a significant effect on flowering time and harvesting. It found that flowering time tends to accelerate, but on harvesting-date parameters tends to be prolonged.
