Abstract: In order to provide cropping arrangement with the suitable combinations of sowing date and rate, filed experiment with 2 factors randomized block design investigated the effects of sowing date and sowing rate on yield and yield components of barley‘Flower 22’. The results showed that the sowing date and rate affected the yield and yield components of barley‘Flower 22’significantly. Sowed on November 4 with 112.5-150 kg/hm2 could obtain relatively high yield which more than 7500 kg/hm2. Meanwhile, the panicle increased with the increasing of sowing rate on the same sowing date, and dropped with the delay of sowing date with the same sowing rate; grain number decreased with the delay of sowing date and the increasing of sowing rate; grain weight increased with the delay of sowing date, and dropped with the increasing of sowing rate. Therefore, combined with the practical cultivation of Chongming Shanghai, the better sowing date of‘Flower 22’between November 4 to 14, the better sowing rate was about 150 kg/hm2, and sowing rate raised appropriately could increase the yield.
