Agronomy and management
Head inclination and stem curvature
Hybrids with pendulous heads tend to suffer less sunscald at flowering than erect hybrids. However, pendulous hybrids with highly curved stems are more prone to lodging, making harvesting difficult, and water may pool in the back of the heads, increasing susceptibility to disease. Ausiclear 20 with a semi-erect head makes the hybrid well balanced to address lodging, sunscald and water pooling issues.
Small to medium seed is preferred for early and / or spring plantings, as smaller seed generally establishes better in cooler conditions. Medium to large seed should be used in warmer conditions or when planting deeper into moisture. Larger seed is more suited to precision planters, as smaller, lighter seed may result in doubles in one hole of the planter plate.
Ausiclear 20 is supplied with OptiCOTE™ Select which includes an insecticide and a fungicide to provide protection against soil dwelling insects and soil borne diseases.
Soil temperate and planting window
For early sowings, the soil temperature at 10 cm depth should exceed 10–12ºC at 8.00 am Eastern Standard Time and the period of heavy frosts should be finished. While 10ºC is the minimum, it is important to plant on rising soil temperatures. Sunflower establishment will be best when 7–10 days of favourable growing conditions immediately follow planting. Extremes of heat or cold may result in patchy plant stands.
Suggested sowing rates
Monounsaturated sunflowers are preferably sown in spring, because higher average night time temperatures during seed development will enhance the oleic acid content.
