has been applied as a green manure to improve soil fertility in southern Ethiopia. It has been nodulated by indigenous rhizobia. The objectives of this study were to evaluate the effects of inoculation with microbial consortia consisted of , and arbuscular mycorrhizal fungi (AMF)on growth, soil nitrogen and phosphorous status after application as a green manure.A field experiment was conducted by inoculating with different microbial consortia. inoculated with the microbial consortia were grown for 150 days. Its shoot length was measured at 60, 90, 120 and 150 days after planting. Then, plants were uprooted and mulched as a green manure. The soil nitrogen, available phosphorous and soil organic matter analysis were done. The experimental design was completely randomized block design with eight treatments comprised of three replications. Inoculated treatments did not show a significant (p < 0.05) difference in shoot length in the first 60 days. However, shoot length was increased between 19.1 and 41.3 %, 10.5-43.4 % and 8.7-37.6 %, respectively at 90, 120 and 150 days. The soil organic matter was improved in both inoculated and un-inoculated treatments. The improvements in the soil organic matter of un-inoculated treatments may be due to the decomposition of un-inoculated plants biomass in the soil. The inoculation improved the soil nitrogen by 17 %. The soil phosphorous was improved in 57 % of inoculated treatments. The inoculation of with microbial consortia enhanced its growth and improved soil fertility when applied as a green manure. Inoculating the green manure legumes with symbiotically effective rhizobia and plant-beneficial microbes can enhance the growth of and its nutrient uptake.
在埃塞俄比亚南部，它已被用作绿肥来提高土壤肥力。它已被本地根瘤菌结瘤。本研究的目的是评估接种由[具体微生物名称1]、[具体微生物名称2]和丛枝菌根真菌（AMF）组成的微生物联合体对其作为绿肥施用后的生长、土壤氮磷状况的影响。通过接种不同的微生物联合体进行了田间试验。接种微生物联合体的[植物名称]生长150天。在种植后60、90、120和150天测量其地上部长度。然后，将植株连根拔起并作为绿肥进行覆盖。进行了土壤氮、有效磷和土壤有机质分析。试验设计为完全随机区组设计，有八个处理，每个处理重复三次。接种处理在最初60天内地上部长度没有显著（p<0.05）差异。然而，在90、120和150天时，地上部长度分别增加了19.1%至41.3%、10.5%至43.4%和8.7%至37.6%。接种和未接种处理的土壤有机质均有所改善。未接种处理土壤有机质的改善可能是由于未接种植株在土壤中的生物量分解。接种使土壤氮提高了17%。57%的接种处理土壤磷得到改善。当作为绿肥施用时，接种微生物联合体促进了[植物名称]的生长并提高了土壤肥力。用共生有效的根瘤菌和对植物有益的微生物接种绿肥豆科植物可以促进[植物名称]的生长及其养分吸收。
