The study was carried out in the nursery of the ministry of agriculture in Bara city in North Kordofan State in the period between June to August (2015). The aim of the study was to investigate the effect of chemical fertilizer (urea) and organic fertilizer (manure) on the growth and yield of okra plant (Umhejarat) and some nutritional elements content in the soil and okra horns. The effect was studied by measurement and analysis of three types of soils (non-fertilizing soil, fertilized with urea and fertilized with manure). Three samples of the soil were taken from three depths (0-20, 20-40, 40-60cm) before the addition of fertilizers and planting of okra to determine the nutritional elements in the soil (as control). A randomized complete block design with three factors was used. 5.0 kg of urea and 300 kg of manure /150 m2 were used. The characters studied include plant height, the number of leaves and number of horns. Sodium, nitrogen, calcium, iron, magnesium, potassium and phosphorus were determined in the dried powdered form of horns and in the three depths in the three types of the soil. The results showed that fertilizing types had a significant effect on the most parameter measured in the study. It was observed that using manure significantly increased the plant height, the number of leaves, number of horns, the content of the elements, the pH, and the yield. The study results showed a significant difference between the elements calcium, magnesium, potassium, nitrogen and phosphorus determined in the three depths of the soil in the three types of the soil but no significant difference was found between the elements determined in the dried powdered form of the horns in the three types of the soil. The study recommends further study to evaluate the effect of different levels of organic fertilizer on okra plant.
