In order to investigate the effect of foliar application of different concentrations of salicylic acid on amino acids yield, yield components and some agronomic properties of rainfed barley, a factorial experiment based on a randomized complete block design with three replications, in 1396 (1997) in a field located in Khorramabad city. Experimental factors included amino acid spraying agent (three levels of spraying with distilled water, amino acid spraying with concentrations of 2 and 4 per thousand) and salicylic acid spraying agent in four levels (distilled water spraying, salicylic acid spraying with 5 concentrations, 1.5 mmol). Results showed that the effect of foliar application of salicylic acid on plant height, grain yield, protein percentage, protein yield and peduncle length were significant. Also, the effect of amino acid on plant height, protein percentage, protein yield and spike length was significant. Also, the interaction effect of salicylic acid and amino acid foliar application on grain yield and protein yield was significant. Came. Based on the results of this study, it can be concluded that spraying of salicylic acid amino acid as an effective method to reduce drought stress in barley agriculture.
