“…However, very limited research data are available on the effect of cuttings at different growth stages of quinoa. Yilmaz et al [49] evaluated the effect of cuttings at three different stages to determine the quality and forage yield of quinoa. Their results revealed that different cutting levels had significant effects on dry forage yield and other morphological and forage quality parameters.…”

Climate change has affected the food supply chain and raised serious food concerns for humans and animals worldwide. The present investigation aimed to assess the effect of environmental factors along with three different levels of cutting (i.e., cutting 1, 2, and 3 at the vegetative, budding, and flowering stages, respectively) and spacing (i.e., 21, 23, and 26 cm) on quinoa biomass and quality to select the most suitable accessions. This experiment was repeated for two years using a split–split plot experimental design. The cutting × genotype × year and cutting × space × genotype interactions were significant for most quinoa morphological traits (except for leaf area and intermodal distance), where the maximum growth in number of leaves/plant (NoL), plant height (PH), fresh weight (FW), number of branches/plant (Br), and dry weight (DW) were observed during the second growing season. Cutting and spacing levels also showed significant effects on morphological and quality traits of quinoa. Among the different levels of cutting and spacing, cutting level 3 and spacing level 2 were more effective across both years at gaining maximum biomass and quality traits such as crude fat (CF) and crude protein (CP). According to the MGIDI, only two accessions (R3 and R9) fared better in both growing seasons, and selected accessions had positive morphological and quality traits. There were moderately significant negative correlations between PH, NoL, LA, FW, and DW and anti-quality traits such as neutral detergent fiber (NDF) and acid detergent fiber (ADF), indicating that an increase in biomass decreased the concentrations of ADF and NDF in both stem and leaves. A comparison with oat accessions (G3 and G7) revealed that quinoa has higher CP and CF and lower NDF than oats in both stems and leaves (except for ADF). In conclusion, the combination of cutting level 3 and spacing level 2 (23 cm) is more suitable to obtain high-quality quinoa forage with maximum biomass production. Furthermore, the MGIDI is a useful tool for breeders to select genotypes based on their mean performance, stability, and desired traits.

“…However, it has not received adequate attention for its importance and unbelievable nutritional values, whereas public awareness of its value and potential does not yet exist (Shams, 2011;Eisa et al, 2017;Zohry, 2020;González et al, 2021). Quinoa has enormous potential; it is not only a gluten-free grain crop (Pereira et al, 2018;Villacrés et al, 2022), but it can also be used as a leafy greens crop (Abd El-Samad et al, 2018a; Pathan and Siddiqui, 2022), a fodder crop (Asher et al, 2020;Yilmaz et al, 2021) and in the food industry (Wang and Zhu 2016; Soliman et al, 2019).…”

It aimed to investigate the effect of applying potassium fertilizer at 90, 140 and 190 kg K 2 O/ha combined with spraying applications of seaweed extract for four times in a 15-day interval starting at 40 days after sowing at rates of 0.0, 1.5 and 3.0 ml/L on the yield, mineral contents and nutritional quality of quinoa grains cv. CICA. A split-plot design was used in three replicates. Results reported that by increasing the application of potassium from 90 to 190 kg K 2 O/ha, gradual increases in all studied parameters of quinoa grains occurred in the seasons of 2016-2017 and 2017-2018, except for class B grain, Mg and fiber contents. Potassium application at 190 kg K 2 O/ha gave the highest significant values of all determined parameters in comparison with treatment of 90 kg K 2 O/ha. In most cases, insignificant differences were detected between potassium fertilizer levels of 140 and 190 kg K 2 O/ha. Spraying seaweed extract at 3.0 ml/L resulted in superiority of all studied characters except class B grain, Mg and fiber contents, followed by 1.5 ml/L treatment with insignificant differences between them in most cases. There were significant differences among spraying seaweed treatments on Ca, Fe, Mn, protein and fiber contents in both seasons, N, P and K during the first season, and grain yield/plant, total grain yield/ha and Zn content during the second season. The interaction between potassium fertilization levels and spraying applications of seaweed extract had significantly different effects on all studied characters during both seasons, except for Mg percentage. It is evident that the application of potassium fertilization at 140 or 190 kg K 2 O/ha combined with the spraying of seaweed extract at 3.0 ml/L caused an apparent enhancement of the yield, mineral contents and nutritional quality of quinoa grains during the two experimental seasons.

“…The major common ingredients are monoterpenes and phenylpropanoids, but their essential oils may vary (Padalia et al 2013). The chemical compositions of plants can be different depending on plant origin, environmental conditions (Atis et al 2012a, Yilmaz et al 2021, Ertekin, 2022, harvesting stages (Atis et al 2012b) and storage methods especially for essential oils, as well as the developmental (ontogenetic) stage (Chang et al 2009). The change in the content of secondary metabolites and their ratio within the plant may vary not only according to these factors but also according to the time of day (Gurbuz et al 2006).…”

The change of essential oil ratios and components of five different basil genotypes harvested at different times (00:00, 06:00, 12:00, 18:00) in day was investigated. Plants were grown under the field conditions and essential oils of the plants were extracted by hydro-distillation method. Identification of essential oil components were performed by GC-MS. It was the G5 genotype that had the highest essential oil content in all plant parts, regardless of the time of day. The highest essential oil content (2.8%) was obtained from the dry leaves of the G5 genotype from the sampling made at 18:00. The main components of essential oils were determined as linalool, eucalyptol, trans α-bergamotene, methyl cinnamate, α-muurolol and eugenol. However, while the ratios of these components differed between genotypes, the changes in time of day were similar for some components. Linalool content tended to increase mostly in the middle of the day. This study indicated that essential oil ratio and components of different basil genotypes significantly differed according to harvesting times in day. Bangladesh J.
