Rhizobia is one of the dominant symbiotic nitrogen fixing bacteria with legumes but a number of factors leads to poor nodulation and nitrogen fixation in legumes. The application of biofertilizer Biological nitrogen fixation (BNF) and mineral soil or N fertilizers are the main sources for meeting the N requirement of high-yielding soybean varieties. Application of biofertilizers along with inorganic fertilizers into the soil leads to increase in productivity of the crop and sustain the soil health for longer period

3.3. Effect of Bio-fertilizer Inoculant on Seed Yield of Soybean
The maximum amount of seed yield (1541.73 kg ha-1) was obtained under application of recommended TSP+ Inoculant. The application of recommended NPS plus inoculation was higher in seed yield of maize by 14% compared to the application of recommended NPS fertilizers alone. The yield advantage relative to NPS alone indicating the depletion of the soil microorganism and its strong response to bio fertilizer application. In line with

[9]
reported that combined application of rhizobia inoculation and phosphorous application resulted in 21% increased grain yield. This is an indication that the integrated use of organic and inorganic nutrient sources of fertilizers was advantageous over the use of inorganic fertilizer alone and also results in synergy and improved synchronization of nutrient release and uptake by the crop. Combined application of both organic and inorganic sources to take care of maize nutrition more effectively leads to better productivity

Figure 6. Effect of bio fertilizer inoculant on seed yield of soybean.
The participant farmers of both kebeles (Amba16 and Jamatsa) ranked the NPS alone at 2nd level, means they were strongly disagree with the NPS alone plot. On the other hand the farmer the farmers had strongly agreed with the plot that received recommended local practice (NPS + inoculant) they scaled as 1st level. This is may be the contribution of microorganisms that by their microbial activity improve the nutrient availability of plants. The application of integrate inorganic and organic fertilizer (biofertilizers) are highly recommended for natural and eco-friendly farming practices that maintain the soil structure and bio-diversity.
4. Recommendation and Conclusion
The most possible causes of this decline soil fertility depletion and the continuous use of the traditional fertilizer, which have limited the yield and crop quality. Therefore this experiment was designed for the purpose of demonstrated combination application of the biofertilizer and NPS, and their combination) for soybean under field condition of Asossa District. Accordingly, the study revealed that application of NPS plus inoculation as the best fertilizer combination for soybean production at Assosa area accordingly farmers perception and the yield data recorded. Application of rhizobium inoculation alone also increased seed yield of soybean might be medium level of ppmP (phosphorous availability) of the study area during experimentation. It can be recommended NPS plus inoculation fertilizer combination to increase productivity and sustainability of soybean for study area and similar agro-ecology with its area.
