[Objective]In order to explore the best sowing date of different millet varieties,we studied corn yield,agronomic traits about millet.[Method]Using split plot experiment,the influence of the sowing date on corn yield,agronomic traits and resistance was studied. [Result]The test results show that the early or later replayed will cause production. Testing varieties Changsheng07,Jingu36,Changnong35 yield were higher.In combination with yield,agronomic traits and resistance,suitable sowing date of Changsheng07,...
