Abstract：In order to determine the best planting time of the mainland owner's planting Panicum miliaceum varieties to the dry area of the western in the west of Xinjiang,and provide theoretical basis and technical support for the high quality and high yield Panicum miliaceum in the cold area of the northern Xinjiang,the test materials were Neimi No.5,Gumi No.21,Shaanmi No.l and Tori No.l,and No.5 sowing dates were set up including Bl(May 15),B2(May 31),B3(June 15),B4(June 30),B5(July 15).The the growth period,growth development and yield changes of Panicum miliaceum varieties under different sowing dates were clarified.The results showed that Panicum miliaceum could not mature normally at the local sowing date B5(July 15)in Qitai,and the other four sowing dates could mature safely,and the growth period of each variety was gradually shortened with the delay of sowing date.Plant height and internode length decreased with the delay of sowing date.Panicle length,panicle weight,1 000-grain weight and yield showed unimodal curve changes,and reached the peak value in B2 treatment.In terms of yield,Neimi No.5,Gumi No.21,Shannmi No.1 and Tori No.1 were suitable for early sowing.The highest yield of Neimi No.5 could reach 3 386.73 kg/hm2 at sowing date of mid-early May.
