Abstract: Abstract Shrinking agricultural land sizes and multiplied food demand have prompted overuse of fertilizers in agriculture, leading to a series of environmental repercussions worsening day after day. In the contemporary scenario, concerns over the magnitude of soil destruction and plant health have shifted the scientific community's attention toward sustainable agricultural practices, including organic farming and the use of organic fertilizers like vermicompost (VC), animal manure, etc. A factorial study using a randomized block design was conducted in the field to appraise the potential of fertilizer and irrigation water on the biochemical and growth responses of Abelmoschus esculentus using different doses of VCs along with and without recommended doses of NPK. All the biochemical analyses were performed at 45 and 65 DAG (days after germination). At both ages, combination of 3-ton ha−1 vermicompost + recommended dose of inorganic fertilizer (120:60:60 kg ha−1) + irrigation water treatments (T5) had the highest protein, chlorophyll, carotenoid, and phenol content and less lipid peroxidation as compared to control (144.28%, 84.21%, 83%, 224.2% and -60.43%, respectively). Also, T5 treatment showed a noticeable increase in the photosynthetic pigments level and reduced heavy metal content in fruits of the test plant at maturity. Statistical analyses, including PCA, Pearson correlation matrix, and MANOVA (p
