The Importance of Sunflower in Agriculture
Sunflower ranks as the fourth most important oilseed crop in the world, after soybean, canola, and peanut.
Sowing Stage of Iranian White-Rimmed Confectionery Sunflower Seed
Sunflower can grow in a wide range of soils, but very heavy soils lacking proper structure are not suitable, as they hinder root development. The best growth occurs in neutral to alkaline soils with a pH between 6.5 and 8.
In well-drained sandy soils, sunflower yields are generally higher than in clay soils. Soil salinity can lead to thin stems, shorter plants, and reduced seed and oil quality.
Sunflower, due to its deep-rooted system, is relatively drought-tolerant, provided the soil has proper depth and structure. Compared to beans or soybeans, this plant is more tolerant to salinity and thrives in neutral pH ranges.
Land Preparation and Tillage for Iranian White-Rimmed Confectionery Sunflower Seed
Tillage sequence for second-season sunflower cultivation:
1. Collecting residues of the previous crop
2. Deep plowing
3. Heavy discing (preferably two perpendicular passes)
4. Use of rotary tiller (if needed)
5. Leveling to even out the soil surface
Planting Time for Iranian White-Rimmed Confectionery Sunflower Seed
The best planting time is when the air temperature reaches a minimum of 8–10°C, which is ideal for seed germination.
The optimum temperature for leaf photosynthesis is between 30°C and 35°C. Sunflower is a heat-loving plant and grows best when the average daily temperature is between 10°C and 35°C.
Optimal temperature for seed production: 21°C to 24°C
Oil content increase: in the range of 21°C to 40°C
Negative effect on oil quality: above 35°C
Recommended Planting Dates Based on Climate:
Temperate and cold regions: mid-April to late May
Warm regions: late January to mid-March
Planting Equipment for Iranian White-Rimmed Confectionery Sunflower Seed
Sunflower can be planted using standard or pneumatic seeders. Any seeder capable of placing seeds on ridges is suitable. Corn and sugar beet seeders can also be used by adjusting the seed distribution plate. However, pneumatic seeders are preferred due to their higher precision.
Planting Depth for Iranian White-Rimmed Confectionery Sunflower Seed
Maintaining the correct planting depth is critical. Planting seeds too deep can:
Delay germination
Deplete the seed's food reserves
Produce weak seedlings
Disrupt the crop’s maturity timing later on
Recommended planting depths:
On ridges: 3 to 6 cm
On flat beds: 3 to 5 cm
In heavy soils: 3 to 5 cm
In light soils: 5 to 7 cm
