Effect of Application of Biofertilizers and Salicylic Acid on Biochemical Characteristics and Grain Elements of Chickpea Cultivars (Cicer arietinum L.) under Rainfed Conditions of Kermanshah

In the present experiment the effect of biofertilizers(non-application of biofertilizers, biosuperphosphate bacteria, biosulfur bacteria, rhizobium bacterium, and mycorrhizal fungus) and foliar application of salicylic acid (non-application, consumption of half and a millimolar)on biochemical chractristics and seed elements in two chickpea cultivars (Bivanij and Azad)was conducted as a factorial form based on randomized complete blocks design with three replications under rainfed conditions in Kermanshah during the cropping year 2016-17. The highest amount of proline was obtained in Bivanij and Azad cultivars in 0.5 millimolar salicylic acid treatment with   biosuperphosphate (0.049 and 0.048 miligram per gram fresh leaf weight, respectively), the highest soluble sugar content of one millimolar salicylic acid treatment in Bivanij cultivars with mycorrhiza and Azad cultivars with rhizobium (2.49 and 2.48 milligram per gram fresh leaf weight, respectively) and the highest amount of soluble protein in one millimolar  treatment of salicylic acid with mycorrhiza and biosulfur (0.172 and 0.167 milligram per gram fresh leaf weight, respectively) was obtained. The highest amount of grain protein in Azad cultivar with application of biosulfur and mycorrhiza (24.83 percent), highest grain raffinose (0.853 percent) in Azad cultivar and with non-application treatment of biofertilizers, highest amount of grain potassium (971.65 milligram per 100 gram) in the treatment of one millimolar salicylic acid with mycorrhizal fungus, the highest grain yield (1821 kilogram per hectare ) was obtained by spraying half a millimolar salicylic acid with rhizobium in Bivnij cultivar. Foliar application of 0.5 millimolar salicylic acid with rhizobium bacteria and mycorrhizal fungus, in addition to improving the biochemical properties and content of elements, led to a 31 percent increase in grain yield compared to the control treatment, which was very economically significant.
