摘要

This 2‑year study (2022–2023) evaluated integrated nutrient management strategies in guava (Psidium guajava cv. ‘Sardar’) production systems. A combination of 80% NPK fertilizer and 20 kg vermicompost per plant achieved a 20% reduction in synthetic fertilizer use while enhancing both productivity and fruit quality parameters. The treatment yielded 219.83 fruits per plant with superior quality metrics: 14.49 °Brix total soluble solids, and 165.36 mg ascorbic acid per 100 g pulp. Predictive models demonstrated a strong correlation between fruit number and weight (R2 = 0.809), providing practical decision-support tools for precision agriculture. These findings promote sustainable agricultural practices that balance productivity with ecological sustainability, supporting growers in competitive markets while reducing environmental impacts through decreased synthetic fertilizer dependency.
