This study was carried out on the “Evaluation of different organic fertiliser sources on agronomic growth performance and yield in okra varieties <em>Abelmoschus esculentus </em>(L) Moench. The study aimed to determine the effect of moringa leaf extract, cow dung, bio-fertiliser and the combined organic fertilisers on agronomic growth performance and yield of okra varieties. The fifteen okra varieties utilised for this study were obtained from the okra germplasm collection at the National Centre for Genetic Resources and Biotechnology (NACGRAB), Department of Plant Genetic Resources, Ibadan, Oyo State, Nigeria. The experiment was a pot experiment whereby the okra varieties were subjected to 5 treatments, which comprise Treatment 1 (Control), Treatment 2 (Moringa leaf extract), Treatment 3 (Cow dung), Treatment 4 (Bio-fertiliser) and Treatment 5 (Combined fertiliser application). The experiment was carried out at the Teaching and Research Farm, Obakekere, Federal University of Technology, Akure. Data were collected on twelve agronomic characters. The application of combined fertiliser was found to greatly influence the rate of growth and yield of the okra varieties, followed by application of bio-fertiliser, followed by application of moringa leaf extract and application of cow dung for all the characters studied. Varieties NGB00466, NGB00380, NGB00322, NGB00305, NGB00342 and NGB00323 were found to be outstanding in terms of number of fruits, total fruit yield and individual fruit weight, irrespective of the type of fertiliser applied. Variety NGB00380 recorded the highest number of fruits. The study shows that the use of organic fertilizer in crop production is desirable as it has a variable impact on the growth and yield of okra and also improve soil organic status, it is also inexpensive, environmentally safe and will not in any way has adverse effect on human health due to the fact that there is no likelihood of any residual property of the organic fertilizer in the crop being used for the production. It can also be shown clearly that the unnecessary additional cost incurred in the cost of the production of okra because of spending on inorganic fertiliser can be eliminated or avoided by solely utilising organic manure from plant and animal sources for okra production.</p> Adewusi, O.F Copyright (c) 2026 Author(s).
