“…This assumption is supported by the results of correlation analysis between the studied parameters, where grain yield showed a positive and significant correlation with aboveground biomass (r = 0.848, p < 0.01 and r = 0.818, p < 0.01 at site A and B, respectively). Similarly to our results, Vishwajith et al [43] found that the seed yield of mungbean (Vigna radiata L. Wilczek) was lower in a sunflower-mungbean rotation system than that of fallow-mungbean, revealing the allelopathic effects of sunflower on the subsequent mungbean crop. In contrast, Cheema et al [44] reported that grain yield of maize crop was increased in the sorghum mulch treatment due to reduced weed-crop interference that resulted in increased leaf area of maize plants.…”

The inclusion of species with allelopathic activity in crop rotation systems may have benefits for crop management such as weed control, but less is understood about their wider impacts on succeeding crops. The main objective of this study was to investigate the effects of two allelopathic species (spearmint and peppermint) on growth, physiological characteristics, and yield of a following maize crop. Thus, field experiments were carried out at two sites, according to a randomized complete block design, while the examined treatments were: (a) fallow–fallow–maize crop rotation system (FFM), (b) spearmint–spearmint–maize crop rotation system (SSM), and (c) peppermint–peppermint–maize crop rotation system (PPM). Our results indicated that the inclusion of spearmint or peppermint in crop rotation systems negatively affect the growth of maize plants. The highest plant height was recorded for FFM rotation system where no allelopathic species were used. At both sites and for four sampling dates, the aboveground dry biomass was also affected by the implemented crop rotation system. In particular, dry biomass was significantly lower in the PPM and SSM crop rotation systems comparing to the FFM system, whereas there were no significant differences between these two crop rotation systems. Similar to the maize biomass, the highest values of photosynthetic rate, stomatal conductance, and relative chlorophyll content were observed for the FFM rotation system. Additionally, differences in grain yield were observed among the tested crop rotation systems. Grain yield ranged from 10,200 to 13,346 kg ha−1 and from 11,773 to 14,106 kg ha−1 at site A and B, respectively, while it was reduced by 16.54–23.58% and 12.16–17.83% in the SSP and PPM rotation systems comparing to the FFM system. In conclusion, our results indicate that the inclusion of peppermint or spearmint in crop rotation may inhibit plant growth and reduce grain yield of maize as successive crop, an effect that could be attributed to the allelopathic activity of spearmint and peppermint.

As for the plumerubroside, it was isolated from a water-soluble extract of the stem bark of Plumeria rubra and also has been found in plantlets of Cunila menthoides and wheat ears at the flowering stage.…”

BACKGROUND The presence of phenolic compounds in sunflower is well reported in the literature; however, knowledge is scarce when it comes to the composition of other secondary metabolites in this species and their by‐products. This work evaluated, for the first time, the phytochemical composition of sunflower meal produced in Brazil. A combination of mixture design and central composite rotatable design 23 models was then applied to maximize the recovery of bioactive compounds using ecologically friendly solvents and concentrating by applying activated carbon, a sustainable adsorbent. The product of this extraction–concentration was also evaluated by an untargeted metabolomic approach using ultra‐performance liquid chromatography coupled to mass spectrometry. RESULTS A diverse and abundant profile of phenolic compounds was obtained from Brazilian sunflower meal: in total, 51 natural products were tentatively identified, 35 of which for the first time in sunflower. The sorption capacity of the activated charcoal, in the optimized process conditions, was effective in the separation and concentration of minority secondary metabolites. The ecofriendly extract proved to be enriched in plumberoside, p‐coumaric acid, and alkaloids. CONCLUSIONS Investigation of the phytochemical profile of sunflower meal produced in Brazil pointed to several secondary metabolites reported for the first time in sunflower samples, including phenolic compounds, alkaloids, and terpenes. The use of activated charcoal in an alkaline medium as an adsorbent for the concentration of these phytochemicals, from an aqueous extract, generated a potentially cost‐effective, ecofriendly extract, enriched in minor metabolites, indicating a possible innovative way to selectively obtain these compounds from sunflower meal. © 2022 Society of Chemical Industry.

“…Seed germination is an essential index for the creation of a desirable plant density and is influenced by many factors, one of the more important of which is the allelopathic action of neighbouring plants (Vishwajith et al, 2017;Marinov-Serafimov et al, 2019). Sunflowers are known to inhibit the germination of some weeds (Kamal, 2011;Oliwa et al, 2017;Lalchand et al, 2021;Chand et al, 2022).…”

“…Sunflowers are known to inhibit the germination of some weeds (Kamal, 2011;Oliwa et al, 2017;Lalchand et al, 2021;Chand et al, 2022). The sunflower residue incorporation increases the concentration of phenolic compounds in the soil that have a harmful influence on weeds germination and crop growth during the early vegetative phase (Vishwajith et al, 2017;Debaeke et al, 2021). It was investigated that extracts of sunflower reduce seed germination and seedling growth of many successive plants (Bashir et al, 2017;Ullah et al, 2017;Sarvadamana et al, 2019;Ravlić et al, 2022).…”
