The effect of organic manure on growth and yield of okra (Abelmoschus esculentus L.)

Field experiments to investigate the effect of different sources of organic manure (poultry manure (3 kg), Cattle manure (3 kg), Swine manure (3 kg), Rabbit urine (1lit)) on growth and yield of okra were carried out. The soil pH was checked and analyzed for pH 6.8 and the soil fertility is 6. The experimental site was cleared and cultivated (tilled and fertilized). Treatments were laid out before planting at once, there was no re-application of treatment. Data were collected on growth and yield parameters (plant height, foliage and fruit weight). There was a significant difference in the height of okra plant treated with poultry manure, cattle manure, swine manure, rabbit urine when compared with the control group. Poultry manure and Cattle manure significantly increase the foliage of okra plant when compared with Swine manure, Rabbit urine and the control. There was significant difference in the fruit weight of okra fertilized with Poultry manure and Rabbit urine when compared with the control but there was no significant difference in swine and cattle manure when compared with the control. From this experimental study, poultry manure and rabbit urine increased the growth and yield of okra and it is recommended for both subsistence farming and commercial production of okra.
