Vermicompost and 50% NPK + 50% vermicompost treatments also showed notable heights at 70 DAS (90.77 cm and 90.80 cm, respectively), significantly outperforming the control (Table 2). The number of leaves was highest in vermicompost (72), followed by control (70), farmyard manure (FYM) (66), and poultry manure (64) at 70 DAS, with the lowest counts in 50% NPK + 50% FYM and 50% NPK + 50% poultry manure (59 each). However, leaf count differences were not statistically significant. Similarly, the number of branches varied slightly across treatments but showed no significant differences.

Fruit length was significantly greater in poultry manure (16.00 cm) than in the control (13.80 cm). Fruit diameter was significantly higher in poultry manure, 50% NPK + 50% poultry manure, and 50% NPK + 50% vermicompost (all 5.17 cm) compared to the control (4.73 cm). Total yield was significantly higher in poultry manure (21.18 ton/ha), followed by vermicompost (16.43 ton/ha), while the control (9.95 ton/ha) and FYM (10.85 ton/ha) recorded the lowest yields (Table 3).
