Abstract: The study examined the individual and combined effects of Aloe Vera Leaf Extract (ALE) (0, 2, and 4 ml L − 1 ) and Date Palm Seed Extract (PSE) (2 and 4 g L − 1 ) on Cumin ( Cuminum cyminum L.) growth, biochemical content/composition, nutrient content/composition, and essential oil profiles. Application of ALE 4 ml L − 1 and PSE 2 g L − 1 as foliar treatments improved the characteristics of reproductive development by increasing seed inflorescence weight and diameter by 122.84% and 58.32%, respectively, compared to the control. Spraying ALE (4 ml L − 1 ), PSE (4 g L − 1 ) + ALE (4 ml L − 1 ) + PSE (2 g L − 1 ) on foliage resulted in an increase of 8.33% in number of flowers per plant and 51.31% increase in total yield/plant. Total phenolic content increased by 10.40%, 8.50% and 8.76% with PSE 2 g L − 1 , PSE 4 g L − 1 and ALE 2 ml L − 1 compared to the control, respectively. ALE at a concentration of 2 ml L − 1 significantly increased the total flavonoid content by 115.59% compared to the control. Carbohydrate content of seeds and leaves increased significantly by 30.27% and 102.55% with ALE 2 ml L − 1 compared to the control, respectively. The ALE 4 ml L − 1 treatment resulted in a 166.66% increase in sulfur, while the ALE 4 ml L − 1 + PSE 4 g L − 1 combination resulted in a 0.239% phosphorus content compared to the control. There were 4 total compounds that were identified from both the 4 ml L-1 ALE treatment and the 4 g L-1 PSE treatment, 1,3-benzodioxole, 4,5-dimethoxy-6-(2-propenyl)-, carvone, D-limonene. These studies suggest that both ALE and PSE can enhance the growth of plants, yield from their harvest, physicochemical properties, and phytochemical profiles; Therefore, enhancing the growth and development of plants through a more sustainable approach to enhance their production and increasing bioactive compound production will be achieved by using environmentally friendly, low-input chemicals such as ALE and PSE.
