Effects of organic manure on okra (Abelmoschus esculentus (L.) Moench) production

Abstract: The effect of different organic manures (cow dung, poultry manure and compost) on the yield of okra, soil physical and chemical characteristics was investigated at the University of Ghana, Legon. Results obtained revealed that the application of recycled garden solid waste compost, poultry manure and cow dung improved the soil physical condition, particularly, structure and drainage, increased nutrient and organic matter levels and enhanced the yield components of okra plants. Inorganic fertilizer improved only chemical properties, but soil physical properties such as structure was not improved. There were improvements in pod yield, yield components and pod fibre content on all manured plots. The study clearly inidicated the superiority of poultry manure over cow dung and compost as a source of manure for okra production.
