This work was carried out in Deir-Elzzor governorate during the season of 2005-2006 to study different forming conditions, on productivity and quality of barley crop. for this purpose, we grew two cultivars : 1.Improved Arabian white barley and 2. Furat-2. These cultivars were grown under the environmental conditions of Deir-Elzzor in the farmer's farms at east of the Governorate. Five levels of fertilizers and two seed rates (20 and 27 kg / donum) were tested. All of these factors were studied to know their effect on productivity of these cultivars of barley and on quantity and quality of their grain protein. Also, protein composition in these grains was studied, Different parts of protein and effect of the studied factors on these composition. We studied amino acids of the protein and their changes under these factors, as well. Results obtained in this work showed that protein quantity in barley grains do not significantly change with different quantities of mineral fertilizer applied, the environmental conditions and the cultivars. Protein content of the two cultivars grains was increased in the treatments where the full dose of fertilizer was applied, while this didn't happen in the control or in the control treatments where P and K were applied. Effect of plant density was obvious on protein quantity particularly more obvious in grains of improved Arabian white barley. Protein content and composition in barley grain are related to the genetic factors, the local conditions and the farming conditions as it were indicted in this research work. Dissolved assimilated protein was increased, glutilin was less increased while albumin and globulin did not change when full dose of fertilizer was used (N60 P60 K60 kg i.e./ha). We found a positive correlation between protein content and non- basic amino acids in barley grains (r = + 0.53), while the correlation was negative between protein content and basic amino acids in barley grains (r = -0.09).
