In order to find out the suitable planting density of Liaodan 1211,a high quality and dense tolerant maize variety,four density levels of 60 000,67 500,75 000 and 82 500 plants/hm2 were set in Daguben Town,Fumeng County,Fuxin City,Liaoning Province in 2023.The effects of planting density on yield and agronomic traits of Liaodan 1211 maize were studied.The results showed that the yield of Liaodan 1211 increased with the increase of planting density,and reached the highest yield of 11 065.00 kg/hm2 at 82 500 plants/hm2;Yield was positively correlated with planting density,negatively correlated with panicle length and 100 grain mass,and negatively correlated with stem size.
