摘要

Intensive chemical fertilization and poor agro-waste management practices have contributed to declining soil fertility and environmental degradation in horticultural systems. Also, there is a growing demand for sustainable strategies to enhance strawberry productivity while minimizing synthetic inputs. This experiment aimed to assess the efficacy of pressmud-derived biochar and plant growth-promoting rhizobia (PGPR) on the agronomic and biochemical response of strawberries (Fragaria × ananassa var. Camarosa). Field experiments were conducted using six treatments involving biochar, PGPR, and their combinations. Biochar was produced from sugar industry waste and characterized using standard spectroscopic and imaging techniques. The results demonstrated that the combined application of biochar and PGPR led to the most significant improvements (p < 0.05) in plant growth, productivity, and biochemical attributes. Results showed maximum values for plant height (29.08 cm), 36.94 leaves per plant, shortest time to flowering (74.42 days), longest harvest duration (75.10 days), 28.50 fruits plant−1, fruit weight (14.51 g), and fruit yield (413.54 g plant−1). Biochemical parameters also improved, including chlorophyll content, ascorbic acid, total soluble solids, and antioxidant content. The treatment also reduced oxidative stress enzyme activities. This study shows the potential of integrating agro-waste-derived biochar and PGPR into horticultural practices as a low-cost, sustainable alternative to synthetic fertilizers which offers a viable strategy for enhancing soil health, improving crop productivity, and promoting circular waste recycling in agriculture.
