摘要

Calcareous soils are nutritionally poor, being a barrier to plants growth and development. Biochar (BC) has been increasingly applied as poor soil supplement to boost crop growth and yield. However, the use of spent mushroom substrate (SMS)-derived BC for such a purpose is still uninvestigated. Therefore, this study aimed to evaluate the potential use of SMS-derived BC in the improvement of tomato attributes grown in calcareous soil. The effects of different concentrations of SMS-derived BC (control (0%), BC1%, BC2%, BC3%, BC4%, and BC5%) on the growth, yield, composition, and antioxidant activity of amended tomato plants were examined. BC4% showed the highest increases in plant growth and yield attributes, photosynthetic pigments (chlorophyll a (Chl a; 64.3%), Chl b (77.4%), total Chl (67.4%), carotenoids (120.0%), vitamin C (101.1%), total phenolics content (TPC; 49.4%), flavonoids (40.2%), lycopene (59.2%), total soluble solids (TSS; 56.7%), total sugars (59.6%), and titratable acidity (58.1%) contents, and antioxidant activity (52.3%) in amended plants compared to control. The antioxidant enzymes (superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX) activities, leaf nitrogen, phosphorus, potassium, carbon, and organic matter contents were also significantly increased (p < 0.05) in amended plants compared to control. SMS-derived BC is a suitable amendment to calcareous soil for enhanced growth, yield, fruit composition, and antioxidant activities of tomato.
