This study was undertaken to determine the effect of planting depth, type of growth medium and method of sowing in the okra cultivar "Chifre-de-Veado". The percentage of germination was 82% in the laboratory. The experiment was conducted in seedbeds and the percentage of germination was recorded.
From the data, the following conclusions were made
1. Germination was directly affected by the planting depth and the type of growth medium, and was not affected by the sowing method.
2. The best emergence was obtained at the depth range of 2.0 - 4.0 cm. The percentage of germination was reduced at the higher planting depths. The germination of the seedlings near the superficial was impaired.
3. The best germination (86.5%) was obtained with sand medium and broadcast sowing.
