Abstract: The aim of this study was to establish the efficacy of herbicide combinations between Tender EC and Titus + Magneto SL, and Wing P and Mistral Opti applied in a field of maize under the conditions of mixed irrigation. The study has been carried out with maize cultivated on meadow-cinnamon soil at the experimental field of the Agricultural Institute – Stara Zagora for the period 2014-2016. The research was conducted with a mid-grade hybrid corn LG35.62 with the same background of fertilization and irrigation with the following variants: 1) Control (without herbicides); 2) Wing P – 4000 ml/ha and Mistral Opti – 210 ml/ha, and 3) Tender EC – 1500 ml/ha and a mixture of Titus – 40 g/ha + Magnet SL – 1200 ml/ha. Increasе of maize yield by 41.6% (on average) in comparison with the control variant and by 28.9% compared to the variant Wing P and Mistral Opti was found.
