Abstract: Abstract Okra (Abelmoschus esculentus L. Moench) is a beneficial vegetable and oil crop that has found valuable use as food, paper, medicine, and oil. However, because of climate change, a lack of better okra cultivars that can resist drought has hampered okra production in sub-Saharan Africa (SSA) and across the world. This study aimed to investigate the economic production of this vegetable in a forest setting. The okra (A. esculentus L.) experiment was conducted underneath three forest trees (i.e. Albizia lebbeck, Melia azedarach, and Leucaena leucocephala) in the agroforestry area. A single-factor Randomised Complete Block Design (RCBD) with three replications was utilised. The sample was then separated into three groups: okra-L. leucocephala agroforestry, okra-M. azedarach agroforestry, and okra-A. lebbeck agroforestry. The findings of the study revealed that okra production had differed significantly in three agroforestry practices. The fresh okra yield was highest (10.20 ton/ha) in the okra-A. lebbeck agroforestry. The okra-L. leucocephala agroforestry (9.10 ton/ha) came in second, while the lowest yield was in the okra-M. azedarach agroforestry (8.90 ton/ha). Moreover, the okra-A. lebbeck agroforestry recorded the maximum benefit–cost ratio (3.97) for economic performance. This ratio was 21% and 14% higher compared to the respective performance of the okra-M. azedarach agroforestry and okra-L. leucocephala agroforestry. However, the highest amount of carbon sequestration (238.90 ton/ha/yr) was measured in the okra-M. azedarach agroforestry as well as (229.80 ton/ha/yr) in the okra-A. lebbeck agroforestry practice. Finally, the okra-A. lebbeck agroforestry practice would significantly increase production, touching financial benefit and ensuring sound environmental quality using the vacant woodlot space.
