Okra is a ubiquitous annual vegetable for its taste and dietary value. The field experiment pursued the effects of vermicompost and inorganic fertilizer on the growth and production of okra. We used three types of fertilizer in this study: control (T3); vermicompost (T1) [5 t/ha]; inorganic fertilizer (T2) [Urea: 80 kg/ha, TSP: 60 kg/ha, MoP: 60 kg/ha]; and two verities of okra, Super Shomy F1 (V1) and BARI Dherosh-1 (V2). Our experiment has some parameters like the height of the okra plants, the length, weight, and diameter of a single pod, the number of leaves, the length of the petiole, the length of the leaves, the days to first flowering, the total pods per plant, the weight of the pods per plant, and the total yield (ton/ha) that are related to vermicompost and inorganic fertilizer. Results showed that all growth and yield parameters were highest in the Super Shomy F1 variety compared to BARI Dherosh-1. Among fertilizer management treatments, vermicompost recorded significant results over inorganic fertilizer on all parameters except leaf number and days prior to first flowering. The control group yielded the lowest outcome across all parameters. As part of the fertilizer management treatment's interaction effect with variety, the highest yield (16.37 t/ha) was measured in V1T1 (Super Shomy F1 × vermicompost), followed by V1T2 (14.50 t/ha), and V2T1 (12.50 t/ha). V2T3 (BARI Dherosh-1 × control) showed the lowest performance (5.4 t/ha). The experiment suggests that applying vermicompost encourages okra to grow and yield more.
