| Abstract | ||
| A field experiment was carried out during the fall agricultural season on 7/25/2021 in the village of Al-Mansuriya, which is affiliated to Hawija district in Kirkuk governorate. In order to study the effect of different herbicides and different seeding rates on the weeds associated with the yellow corn crop and its effect on the yield and its components. The experiment was carried out according to a randomized complete block design, R.S.B.D. Two factors were studied, the first: three seed rates were used, A1 = 36 kg/ha, A2 = 46 kg/ha, and A3 = 56 kg/ha. Various herbicides were used and in concentrations were Atrazine (b2) 1440 g/ha), Nicosulfuron + Atrazine (b3) (100 g/ha), Atrazine (b4) + Rimisulfuron 50 (g/ha), with 250 ml of adhesive and diffuser) and Atrazine (b5) + Nicosulfuron + Rimisulfuron in the same quantities. With the control treatment (b1) (Control. As for the second factor: different herbicides were used with concentrations, it was Atrazine (b2) 1440 g / hectare), Nicosulfuron + Atrazine (b3) 100 g / hectare) and Atrazine (b4) + Rimisulfuron 50 ) g/ha, with 250 mL adhesive and diffuser) and Atrazine(b5) + Nicosulfuron + Rimisulfuron in the same quantities. With the control treatment (b1) (Control. The results showed significant differences in the characteristics of the total number of bushes and dry weight in the treatments of seed quantities, while in the factor of herbicide concentrations, the double and triple mixtures excelled compared to using atrazine for the unit and comparison treatment. As for the characteristics of the yield, the results were shown The recommended seed quantities, which amounted to 36 kg/ha, gave clear significant differences in the characteristics of earlobe weight/g, weight of 300 grains/g, and grain yield ton/ha, with their averages reaching 118.60 gm, 82.74 gm, and 3.497 ton/ha, on the The triple mixture consisting of (Atrazine, Nicosulfuron, Rimsulfuron) gave the highest significant difference in the characteristics of the ear weight/gm, the weight of 300 grains/gm and the grain yield, ton/ha, with their averages reaching 113.11 gm, 84.87 gm and 3.672 ton.ha-1, Straight. | ||
