Abstract:\u00a0<\/strong><\/span><\/p>\n

The experiment was carried out at the Saalo Research Station of the Agricultural Scientific Research Center in Deir Ezzor (30 km east of Deir Ezzor) through the season 2020 , with the aim of determining the most important types of weeds that accompanies with maize, and evaluating the effectiveness of four rates of application of the herbicide (2,4-D) (0.5, 0.75, 1 and 1.25 L\/ha) in controlling broadleaf weeds under different rates of seeds (2.5,3,3.5 kg\/ dunum) in the competitiveness between maize crop with weeds and their effect on growth and productivity. The efficiency of herbicide was 81.3% at the rate of application 1.25 liters \/ hectare when the seed rate was 3.5 kg \/ dunum, and the dry weight of the weeds decreased to 70.8 g\/m\u00b2 while the dry weight of yellow corn increased to 221.1 g\/m\u00b2 .The average height of the maize plant increased to 150 cm and the weight of 100 kernels increased (33.1 g) at the rate 1.25 liters \/ hectare and the higher seed rate, it also achieved the highest grain yield recorded 15,617 tons\/ha. The highest seed rate was significantly superior to all the studied treatments, and the yield was increased. The treatment of weed control with a seed rate 3.5 kg\/dunum was superior in all studied treatments compared with using the herbicide.<\/span><\/p>\n
