Sunflower Cultivation Guide in Afghanistan
Practical sunflower production guide for Afghanistan: climate, soil, irrigation, stage-based nutrition, deficiencies, pests, diseases and harvest.
Introduction and importance
Sunflower is an important oilseed or industrial crop; uniform establishment and timely harvest determine quality.
Suitable climate and soil
Suitable conditions are sunny; deep well-drained soil. Test soil and water before planting.
Land preparation and planting
Use healthy seed in warm soil at water-matched population; match date, depth and population to the location.

- Stage 4: رسیدگی و برداشتAdjust nutrition to crop demand and laboratory soil and water results. Avoid mixing concentrated fertilizers without a compatibility test.
Nutrient deficiencies
Diagnose deficiencies from symptom pattern, affected leaf age, root condition and laboratory analysis. Similar symptoms may also result from salinity, waterlogging, cold or root disease.
Pests and diseases
Key pests are cutworms, aphids, head moths and birds; scout and use integrated management. Key diseases are mildew, rust, Sclerotinia and stalk rots; use clean seed, rotation, drainage and residue management.
Harvest and storage
Harvest when head backs are yellow-brown and bracts dry, then dry, clean or process promptly.
