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 →La rouille noire du blé (Puccinia graminis f. sp. tritici) cause des pustules brun-rougeâtre sur les tiges, les gaines foliaires et les feuilles. La race Ug99 est une menace mondiale majeure. Gérez avec des variétés résistantes portant les gènes Sr31+Sr38 ou Sr25, des semis précoces et des pulvérisations préventives de fongicides (tébuconazole ou propiconazole) au premier signe de pustules.
La rouille jaune du blé (Puccinia striiformis) produit des stries de pustules jaune-orangé vif le long des nervures foliaires. Elle préfère le temps frais (10-18°C) mais de nouvelles races adaptées au chaud étendent son aire. Appliquez du propiconazole ou du tébuconazole à l'émergence de la feuille étendard, plantez des variétés résistantes et évitez les semis tardifs en régions fraîches et humides.
La pyriculariose du blé est causée par Magnaporthe oryzae pathotype Triticum. Maladie émergente dévastatrice, elle provoque le blanchiment des épis et des pertes pouvant atteindre 100 %. Guide de traitement et prévention pour les producteurs de blé.
