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.

Evaluation the effect of drought stress and foliar nutrition of iron nano-chelate and fulvic acid on grain yield and fatty acids composition in seed oil of two sesame cultivars was conducted during a factorial split-plot experiment based on randomized complete block design with three replicates in 2017 in the Research Farm Shahed University of Tehran. The experimental factors included drought stress in three levels: full irrigation as control, irrigation up to 50% seed ripping, and flowering, as well as four treatments of foliar nutrition by iron nano-chelate and fulvic acid in Dashtestan and Halil cultivars. The results showed that the drought stress reduced grain yield and also, seed oil content. The highest grain yield was observed in full irrigation (2303.3 kg/ha) and the co-application of iron nano-chelate and fulvic acid (2246.4 kg/ha). Halil cultivar had the highest mean of the total number of capsules (81.19), number of seeds per plant (4786.1), 1000-grain weight (3.21 g), grain yield (2172.7 kg/ha), and biological yield (13534.6 kg/ha) in compared with Dashtestan. The highest oil and protein yield were observed in full irrigation and irrigation up to 50% seed ripping. Irrigation cut off at 50% flowering and seed ripping had the highest oleic and linoleic fatty acids compared to the control treatment, but the highest palmitic and stearic fatty acids were obtained in full irrigation treatment (10.86 and 10.73%, respectively). Halil and Dashtestan cultivars had the highest unsaturated and saturated fatty acids, respectively.
