A field experiment was conducted at Welmera, Ada’a Berga and Kersa Malema districts of Ethiopia during 2016 and 2017 cropping seasons to evaluate the effect of PGPMs consortium (Panoramix product) on yield of wheat and malt barely. The treatments were untreated control, Recommended NPS, Panoramix coated seed, Imidalm/Apron Star and Panoramix coated seed, Panoramix + Recommended NPS, and Imindalem/ Apron Star + Panoramix + Recommended NPS and laid out in randomized complete block design with four replications. Statistically significant differences (P≤0.05) were observed among treatments for grain yield of wheat and malt barely in all locations and seasons. The highest wheat grain yields at Welmera and Kersa Malema, and Ada’a Berga were 4617, 3080 and 4360 kg ha-1, respectively and obtained from Panoramix + 182 kg NPSB and 55.4 kg urea ha-1. In malt barely, the average grain yield (3554 and 2563.6 kg ha-1) at Welmera and Kersa Malema, respectively were obtained from Apron Star + panoramix + 121.08 kg NPSB and 39.16 kg urea ha-1 despite at par with the sole recommended NPS, which had the peakiest average grain yield (2749.6 kg ha-1) at Ada’a Berga. The result generally confirmed, PGPMs consortium (panoramix product) co-application with mineral fertilizer on wheat and malt barely did not show agronomic and economic superiority over sole recommended mineral fertilizer. But, at Welmera, paronamix + Apron star + Recommended NPS treatment was feasible though not showed significant grain yield change.
