Abstract: To ascertain effects of sowing dates on the yield and quality of both forage and grain among different barley varieties, four sowing dates(factor A)were imposed on four six-row barley varieties(factor B)to compare the differences of yield and quality of tillering forage and mature grain. The results showed sowing dates had a greater impact on forage yield and less impact on grain yield. Early sowing accelerated cutting times and raised forage yield while the highest forage fresh weight(12.44 t/ha)and dry weight(1.49 t/ha)were obtained at sowing date A1(September 30). Significant differences were identified among varieties for both forage and grain yield. Variety B2(Wansipi 14008)achieved the highest forage fresh weight of 10.51 t/ha and dry weight of 1.38 t/ha, and the second highest grain yield of 1.82 t/ha. Variety B1(Yangsimai No.1)achieved the highest grain yield of 3.58 t/ha and the second highest forage fresh weight of 9.00 t/ha and dry weight of 1.17 t/ha. Thus variety B1 and B2 can be used for harvest of both forage and grain. Sowing dates had a greater effect on forage quality but less effect on grain quality. Forage quality traits excluding acid detergent lignin content varied significantly among sowing dates of which A2 and A4 had greater values for corresponding traits. No significant differences were found among varieties for forage quality traits, which can be used as elite forage crops. Differences of grain quality were significant among varieties of which B2 had the highest protein content and B1 had the highest starch content, implying selection of varieties can improve feed quality. Interaction of sowing dates and varieties had a certain effect on forage yield but little effect on other traits. Based on the above analyses, Wansipi 14008 and Yangsimai No.1 can be used and sowed on September 30 to achieve harvest of both elite forage and grain.
