In order to evaluate the effect of salicylic acid and mycorrhizal in reducing salinity damage on the quantitative and qualitative yield of marigold a factorial pot experiment was conducted based on completely randomized design . This experiment was carried out with four replications in the Poldokhtar Payam Noor University in 2015. Experimental factors including salinity in 5 levels (Poldokhtar drinking water with electrical conductivity of 0.7 dS.m-1 is control), 2, 4, 6 and 8 dS.m-1, 4 levels of salicylic acid 0, 0.3, 0.6, and 0.9 mM and mycorrhiza was inoculated and no inoculated. The results showed that salinity reduced all the measured traits but only increased the antioxidant property. Consumption of Salicylic acid and mycorrhiza improved all the traits in salinity . The highest amount of chlorophyll a and b were in 0.7 dS-1 salinity and application of 0.6 mM salicylic acid with 0.115 and 0.207 mg.kg-1 fw, respectively which was significant with other treatments in 5%. Petal carotenoid was in 0.7 dS-1 salinity and application of 0.9 mM salicylic acid with 7.71 mg.kg-1 fw which was 15% higher than the same salinity and without using salicylic acid. The maximum of fresh weight of inflorescence content as economical yield with 12.56 gr.pot-1 was observed at 0.7 dS-1 salinity, 0.9 mM salicylic acid and mycorrhizal inoculation. Mycorrhiza increased 28 percent antioxidant properties and 21 percent colonization compared to the control treatment. Mycorrhiza by absorbing more water and nutrients in salinity improve the growing conditions of the plant and increase the yield.

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.

In order to study the effect of the usage of vermicompost and mycorrhiza fertilizer usage on yield quantity and quality of soybean cultivar L17 in water deficit stress condition, an experiment was conducted as plots in a split at randomized complete blocks with four replications in Agricultural Research Center in 2013 in Khoramabad. The experiment treatments including irrigation in three levels (after 60, 120 and 180 mm evaporation from pan class A pan), vermicompost and mycorrhiza in six levels (non-use of vermicompost and mycorhiza fertilizer, inoculated with mycorrhiza fertilizer, consumption of 5 and 10 t.ha-1 vermicompost , consumption of 5 and 10 t.ha-1 vermicompost with mycorrhiza) were respectively as the main plots and sub. The results of experiment showed that the water deficit stress significantly decreased the number of pods per plant, number of grain per pod, number of grain per plant, 1000 grain weight, biological and grain yield. So that the highest grain yield with the rate of 3216.7 kg.ha-1 was obtained from 60 mm evaporation. The use of combined vermicompost and mycorrhiza fertilizer increased the traits except the number of grain per pods. Grain yield in combined treatment of 5 and 10 t.ha-1 vermicompost and mycorrhiza, respectively increased 23 and 29 percent compared to control. By increasing irrigation distance grain oil content decreased and grain protein content increased. Finally, in order to water_saving irrigation and the cost of inputs and ensuring optimal performance in drought condition, we can use combination of 5 t.ha-1 vermicompost with mycorrhiza.
