A greenhouse experiment was conducted to study the relative effect of organic and inorganic fertilizers on the growth of okra (Abelmoschus esculentus). The experiment consisted of four treatments. Cow dung and poultry droppings were applied at the rates of 2.5 kg per 10 kg of soil one week before sowing, while NPK fertilizer (15:15:15) was applied at the rate of 6 g per 10 kg of soil three weeks after sowing. The treatments were laid in a completely randomized design with three replications. Plant growth was assessed using plant height, fresh weight, leaf area and dry weight. The application of cow dung, poultry droppings and NPK fertilizer had significant effects on all the parameters assessed. The application of poultry droppings gave plants with the greatest plant height, leaf area and fresh weight, while cow dung application gave the greatest dry weight. The data obtained from these treatments were significantly higher than the data obtained from the control. It was, therefore, concluded that the use of organic manure in the production of vegetables like okra should be encouraged. Ogled je sproveden u stakleniku kako bi se proucio relativni uticaj organskog i neorganskog djubriva na rast bamije (Abelmoschus esculentus). Ogled se sastojao od cetiri tretmana. Govedji stajnjak i zivinsko djubrivo su primenjeni u kolicinama od 2,5 kg na 10 kg zemljista nedelju dana pre setve, dok je NPK djubrivo (15:15:15) primenjeno u kolicini od 6 g na 10 kg zemljista tri nedelje posle setve. Ogled je izveden po metodu potpuno slucajnog blok sistema u tri ponavljanja. Rast biljaka je ocenjivan uzimajuci u obzir visinu biljke, svezu masu, lisnu povrsinu i suvu masu. Primena govedjeg stajnjaka, zivinskog djubriva i NPK djubriva je znacajno uticala na sve parametre koji su ocenjivani. Primena zivinskog djubriva je dala biljke sa najvecom visinom, lisnom povrsinom i svezom masom, dok je primena govedjeg stajnjaka dala biljke sa najvecom suvom masom. Podaci dobijeni primenom ovih tretmana su bili znacajno visi nego podaci dobijeni kod kontrolnog tretmana. Na osnovu toga zakljuceno je da treba ohrabrivati upotrebu organskog djubriva u proizvodnji povrca kao sto je bamija.
