Across all observation periods—25, 30, 35, and 40 days after sowing (DAS)—California Wonder (V2) consistently exhibited longer seedlings than Sagar Hybrid F1 (V1). At 40 DAS, V2 achieved a maximum seedling length of 4.66 cm, while V1 reached 3.90 cm, with mean values of 3.14 cm and 2.65 cm, respectively. Growth media composition had a significant effect (p < 0.001) on seedling elongation at all developmental stages. The highest seedling length was observed in M5 (Soil + Cocopeat + FYM + Vermicompost in 1:1:1:1), recording 6.91 cm at 40 DAS. This was followed by M4 (Soil + Vermicompost) with 5.25 cm, and M3 (Soil + FYM) with 4.46 cm.
