The experiment was conducted on the growth and yield of okra using nutrient management through different types of fertilizers and netting at the Horticulture Farm of Bangladesh Agricultural University (BAU), Mymensingh. There were netting treatments, viz. N1 = Control (no net) and N2= Net (blue color) along with fertilizer treatments viz. T1 = no fertilizer (control), T2 = vermicompost @ 10 t ha−1, T3 = vermicompost @ 15 t ha−1, T4 = combined application of 2/3 part organic (T3) and 1/3 part inorganic (T5), and T5 = inorganic fertilizers. Temperature (◦C) and relative humidity (%) were recorded under net and at the open condition daily during production stage (month of May) However, the value didn’t differ significantly. Growth parameters of okra viz. plant height, pod length, pod diameter, and pods of okra were found the highest from T4N2 treatment combination which was significantly higher from other combinations. The lowest growth and yield of okra was found from the treatment combination of T1N1. First flowering was observed in T4N2 at 32 days after planting of okra seeds. Vermicompost at different rates (10 t ha−1 and 15 t ha−1) with net gave lower production of okra compared to inorganic fertilizer treatments with net. The highest yield of okra (19.65 t ha−1) was found from the combined effect of T4N2 which was 56.74% higher compared to control (T1N1).
