Yield response and it's components of faba bean genotypes under different levels of challenge herbicide

Abstract EN

Study was carried out to evaluate weed on faba bean genotypes yield ( Akuadcye , Flip 17-08FB, FLI17 – 072 FB and Fido) under different levels of Challenge herbicide (0.0 , 1.0, 1.5 and 2.0 Lha-1 ) during winter season 2020-2021 at experimental station /Duhok University.

The factorial experiment was carried out with Randomize Complete Block Designin three replications The results showed that the Challenge herbicide levels reduce the number of Monocotyledon and Dicotyledonous weeds.

Also, the results presented significant effect of genotypes, challenge levels and genotypes x genotypes levels interaction.

The interaction between Fido-2Lh-1 significant effect on plant height (63.83 cm), first pod height (23.83 cm) , number of main branches per plant (4.48), number of pods per plant (18.15) , 100 seed weight (122.18 g) and total yield 2682 kg ha-1 which could be to the effect at rate 2Lha-1 in reducing Monocotyledon and Dicotyledon weeds .
