An experiment is conducted to evaluate effect of Bacillus and Pseudomonas on Quantitative and Qualitative Yield and malting efficiency of different Barley cultivars in rainfed conditions in a farm of Ilam Agriculture and Natural Resources Research Center in 2017 and 2018. The experiment is factorial according to randomized complete blocks design with four replications. Three cultivars (namely, Behrokh, Grace, and Sararoud1 as first and seed inoculated with growth-promoting bacteria) and Fertilizer at eight levels (including the control, complete fertilizer (Field recommendation), Pseudomonas bacteria, Bacillus bacteria, combination of Pseudomonas and Bacillus bacteria, Pseudomonas bacteria + half fertilizer, Bacillus bacteria + half fertilizer and combination of Pseudomonas and Bacillus bacteria + half fertilizer) are considered second factor. The results show that all the studied traits (with the exception of malting efficiency) addition main effect, are significantly affected by year interaction in cultivar in fertilizer treatment, but malting efficiency is influenced by interaction cultivar in fertilizer treatments. Heights number of seeds per spike, number of spikes per m-2, and grain yield are recorded by a combination of Pseudomonas and Bacillus bacteria + half fertilizer under garis cultivar with means 31, 390 and 5294 kg/h in 2018 and 35, 400 and 6222 kg/h respectively. Maximum malting efficiency (95.5 %) has also been observed in the combination of Pseudomonas and Bacillus bacteria + half fertilizer under Behrokh.
