Abstract: Soil fertility depletion and acidity are critical issues for soybean production in western Ethiopia. Biofertilizers and inorganic fertilisers can improve crop productivity and soil health. Tests were conducted on farms using elite soybean rhizobial inoculant and nutrient integrations in acidic soil. Results showed that the application of differentiated application (N + TSP + Inoculant) was the best fertiliser combination for soybean production in the Assosa area. The study found that the differential application yielded the maximum amount of seed yield (1410.1 kg ha-1). However, it was not significantly different from other treatments. The study also found that rhizobium inoculation alone also increased soybean seed yield, possibly at a medium level of phosphorous availability in the area.
