Introduction Sustainable nutrient management is essential for improving guava fruit quality and reducing reliance on chemical fertilizers. Methods A field experiment was conducted during 2022–2024 at SKUAST-Jammu using a Randomized Block Design with 16 treatments and 3 replications. Organic inputs (vermicompost, biochar, jaggery, etc.) were evaluated. Results Treatment T6 (VC 5 kg + BC 7.5 kg + JG 1.25 kg/tree) recorded highest TSS (13.72°Brix), total sugars (10.10%), Vitamin C (175.27 mg/100 g), and lowest acidity (0.24%). Discussion Integration of vermicompost, biochar, and jaggery significantly improves fruit quality and supports sustainable guava production.
