Abstract Background Quinoa seeds contain highly nutritive compounds, so it acquired increasing interest during the last years Materials and methods A field experiment was conducted at the experimental station of Agricultural Production and Research Station, National Research Centre, El Nubaria Province, El Behaira Governorate, Egypt, during two successive winter seasons (2016/2017 and 2017/2018). In this experiment, quinoa plants were sprayed with clove extract of garlic or leaf extract of Eucalyptus globulus with concentrations 5, 10 and 15% in addition to the untreated control treatment. Quinoa plants were sprayed twice 86 and 93 DAS (days after sowing). Results The results of vegetative growth stages indicated increases in quinoa growth due to the treatments with different concentrations of the two mentioned extracts. The results also revealed increases in photosynthetic pigments constituents (chlorophyll a, chlorophyll b and carotenoids) of quinoa leaves. The results also indicated increases in yield and oil content as well as different studied metabolic activity. Conclusion We can conclude from these results that spraying quinoa plants with natural clove extract of garlic or leaf extract of Eucalyptus for increasing growth and consequently yield.
