Abstract :
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.
