Effects of nutrient management and netting on growth and yield of okra

Abstract

The experiment was conducted on the growth and yield of okra using nutri- ent management through different types of fertilizers and netting at the Hor- ticulture 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 pa- rameters 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).
