The Effects of Different Sowing Dates on Agronomic Traits,Lodging Resis-tance and Yield of Prosomillet
Six different sowing dates were set up to study the effects of sowing dates on the growth period,agronomic traits,lodging resistance traits,and yield of millet.The results showed that the impact of sowing date on the growth period was mainly from seedling emergence to heading stage,and the growth period shortened with the delay of sow-ing date.As the sowing date is postponed,the agronomic traits such as plant height,number of main stem nodes,and main spike length of the millet decrease,and the ability to resist lodging is strengthened.The highest yield was reached on May 28th,reaching 3 540.0 kg/ha;The sowing date is June 4th,followed by a yield of 3 430.0 kg/ha.Therefore,it is suitable to sow millet in the Tongliao Region from May 28th to June 4th,and it is not advisable to sow it too early or too late.
