In 2022 and 2023 a field experiment with the maize hybrid P 9610 was conducted. The trial was performed on the experimental field of the Agricultural University - Plovdiv, Bulgaria. The variants of the experiment were: 1. Untreated control; 2. Economic control; 3. Aminopielik 600 SL (1.20 l ha-1); 4. Arigo WG (0.33 kg ha-1); 5. Callam (0.40 kg ha-1) 6. Starane Gold (1.20 l ha-1). The herbicides were applied in the crop growth stage 3rd-5th leaf (BBCH 13-15). The weed infestation was represented by Chenopodium album L.; Amaranthus retroflexus L.; Xanthium strumarium L.; Abutilon theophrasti Medik., and Solanum nigrum L. The highest weed control against Ch. album, A. retroflexus, and A. theophrasti after the application of Callam was recorded, and against X. strumarium and S. nigrum after the application of Starane Gold. For the Economic control as well as for the variants treated with herbicides, the parameters ear diameter, ear length, number of seeds per ear cob, absolute seed mass, hectoliter seed mass and grain yield were higher and mathematically proven compared to the untreated control’s results for these parameters.
