Effects of Different Sowing Dates on Wheat Yield Traits in Eastern Henan
To elucidate the relationship between wheat yield and sowing date,new wheat varieties with broad suitable sowing dates were selected to ensure wheat production in the eastern region of Henan.Six wheat varieties were selected and a two-year experiment was conducted from 2020 to 2021 and 2021 to 2022 at the Shuangba Base of Shangqiu Academy of Agriculture and Forestry,assessing the effects of sowing dates on wheat yield and yield traits.The results indicated that sowing date and different varieties had a significant effect on wheat yield.The sowing dates also had a significant effect on plant height,highest population,number of ears per 667m2,percentage of mature ears,and 1 000-grain weight;1 000-grain weight and yield reached their highest at T2 sowing date(October 15th),and were significantly higher than other sowing dates.Among the six varieties test-ed,'Shangnong 6'has the highest plant height,ear number per 667 m2,1 000-grain heavy ear rate and yield under different sowing periods.
