The identification of compounds with allelopathic potential produced
by cover crops can assist in selecting species for weed management purposes in
no-tillage systems. This study aimed to identify the main phenolic compounds with
allelopathic potential in the shoot of rye (Secale cereale L.) and radish (Raphanus
sativus L.) cover crops, as well as evaluate whether the cultivation system and
phenological stage may influence secondary metabolite production and weed
emergence. Samples of the shoot of these cover crops were collected at 60, 80, and
100 days after sowing (DAS) and 15 and 30 days after lodging (DAL) under field
conditions. Weed emergence was evaluated at 45, 75, and 100 DAL of cover crops.
The main compounds in rye were 6-methoxy-2-benzoxazolinone (MBOA) and
2-benzoxazolinone (BOA) under monocropping and intercropping, while flavonoid
quercetin was found in radish at all evaluated times. During the growing cycle, the
highest contents of phenolic compounds were found at the elongation stage
(60 DAS) of rye under monocropping and intercropping systems (9.33 and 8.22 mg g-1
DM, respectively) and at grain filling stage (100 DAS) for radish intercropped with
rye and black oat (3.24 and 3.83 mg g-1 DM, respectively). No differences were found
in the contents of the main compounds when the species was grown under
monocropping or intercropping systems. A reduction in the contents of MBOA,
BOA, and quercetin was observed after lodging. Weed dry matter production was
lower at 45 DAL in all treatments with rye and radish residues when compared to the
control. The intercropping of rye with radish is an alternative management for weed
control in agroecological systems due to the physical barrier created by these species
and the presence of phenolic compounds with allelopathic potential. MenosThe identification of compounds with allelopathic potential produced
