A field experiment was carried out during the fall agricultural season on 7/25/2021in 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 weedsassociated with the yellow corn crop and its effect on the yield and its components.Theexperiment was carried out according to a randomized complete block design, R.S.
B.D.Twofactors were studied, the first: three seed rates were used, A1 = 36 kg/ha, A2 = 46 kg/ha, andA3 = 56 kg/ha.Various herbicides were used and in concentrations were Atrazine (b2) 1440g/ha), Nicosulfuron + Atrazine (b3) (100 g/ha), Atrazine (b4) + Rimisulfuron 50 (g/ha), with250 michael harris sunglasses ml of adhesive and diffuser) and Atrazine (b5) + Nicosulfuron + Rimisulfuron in thesame quantities.
With the control treatment (b1) (Control.As for the second factor: differentherbicides 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 thesame quantities.With the control treatment (b1) (Control.The results showed significantdifferences in the characteristics of fr5947 the total number of bushes and dry weight in thetreatments of seed quantities, while in the factor of herbicide concentrations, the double andtriple 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 seedquantities, which amounted to 36 kg/ha, gave clear significant differences in thecharacteristics of earlobe weight/g, weight of 300 grains/g, and grain yield ton/ha, with theiraverages reaching 118.60 gm, 82.74 gm, and 3.497 ton/ha, on the The triple mixtureconsisting of (Atrazine, Nicosulfuron, Rimsulfuron) gave the highest significant differencein the characteristics of the ear weight/gm, the weight of 300 grains/gm and the grain yield,ton/ha, with their averages reaching 113.
