Soil Requirement

Sunflower can be grown on a wide range of soils but soils with good drainage are best suited. It grows well on neutral to moderately alkaline soils, with a pH range of 6.5 to 8.0 but acidic soils are not suitable. Poor drainage conditions are unsuited because it increases susceptibility to fungal disease and lodging.
