      abstract = {Okra (Abelmoschus esculentus L. Monech) is an important vegetable crop consumed for its rich minerals and vitamins, but little is known about the presence and concentration of other rich nano particles like Melatonin in its fruits. A study on the effects of planting dates on the phenology, yield and melatonin concentration in Okra (Abelmoschus esculentus L. Monech) fruit was carried out during the planting season of 2023 at the Teaching and Research Farm of Rufus Giwa Polytechnic, Owo. The experiment was laid out using Randomized Complete Block Design (RCBD). The treatments comprised of three planting date (D1=1/7/23, D2=8/7/23 and D3=15/7/23) randomized into plots by table of random numbers. Each plot measures 2.50 x 1.50m with work space of 0.5m between plots. Treatments were replicated four times in each block. The result of the study showed that second planting date had significant effect on the phenology and yield okra fruit. Also, presence of melatonin was identified in okra fruit and its concentration was influenced by third planting date in the study area. This is an indication that appropriate planting date improves the yield and melatonin concentration in okra},
