Wheat
Triticum aestivum
About Wheat
Wheat is the most widely grown crop by harvested area and the second most produced cereal after maize. It provides approximately 20% of global food calories and protein. Bread wheat (T. aestivum) is the dominant species, with durum wheat (T. durum) used for pasta. Wheat is a cool-season crop critical to food security in South Asia (India, Pakistan), North Africa, the Middle East, and increasingly in East Africa. India is the world's second-largest wheat producer. The Green Revolution wheat varieties developed by Norman Borlaug saved an estimated billion lives. Modern challenges include emerging threats from wheat blast and new rust races adapting to warmer conditions.
Growing Conditions
Full sun — long day plant, requires 12+ hours of daylight for optimal development in many varieties
350-650 mm per crop. Most critical water demand is at booting through grain fill. Drought or heat stress at flowering causes severe yield loss.
Well-drained loam to clay loam. pH 6.0-7.5. Wheat tolerates slightly alkaline soils better than most cereals.
Optimal 15-24°C for growth, 12-18°C for grain fill. Vernalization (cold period) required for winter wheat types.
Low to moderate preferred. High humidity promotes rust, Fusarium head blight, and Septoria.
Cool season — winter wheat sown in autumn, spring wheat sown in spring. 100-150 days to maturity.
Step-by-Step Growing Tips
Select variety suited to your latitude and sowing date (winter vs spring type)
Sow at recommended date — early sowing for winter wheat, timely for spring wheat
Apply nitrogen in splits: at sowing, tillering, and flag leaf
Scout for rust regularly from tillering through grain fill
Harvest promptly when grain moisture reaches 12-14% to avoid weather damage
Rotate with broadleaf crops (legumes, oilseeds) to break cereal disease cycles
Disease Risks to Watch
All diseases →صدأ ساق القمح يسببه Puccinia graminis ويُحدث بثرات حمراء-بنية على السيقان والأغماد. سلالة Ug99 تهدد ٩٠٪ من أصناف القمح العالمية. يُدار بأصناف مقاومة (جينات Sr2+Sr31)، مبيدات فطريات مثل التيبوكونازول والبروبيكونازول، والقضاء على نبات البرباريس المضيف البديل.
الصدأ المخطط للقمح يسببه Puccinia striiformis وينتج خطوطاً من البثرات الصفراء على الأوراق. يفضل الأجواء الباردة الرطبة. يُدار بأصناف مقاومة ومبيدات فطريات تريازولية (تيبوكونازول، بروبيكونازول) وزراعة مبكرة وتسميد متوازن.
