Wheat has the largest planted area of any crop in Türkiye. The key to yield and grain protein is setting up base fertilization correctly and supplying nitrogen and trace elements in balance at critical stages. In field crops, base nutrition goes to the soil; Agrorun's foliar biostimulant products support this program at critical stages. This guide presents a stage-by-stage wheat fertilization program.
Soil Analysis and a Critical Warning: Zinc
The program must start with a soil analysis. Across much of Türkiye, especially Central Anatolia, zinc deficiency is widespread and severely reduces wheat yield. Always determine your zinc status by analysis; if deficient, a zinc-containing base fertilizer or a foliar zinc program is essential. Use our free consultancy to interpret the results.
Fertilization Program by Growth Stage
1. Sowing and Emergence Stage
Phosphorus is important for strong roots and emergence; base fertilization (usually DAP or a compound) is applied to the soil at sowing. On fields with known zinc deficiency, a zinc-containing base fertilizer is preferred.
2. Tillering Stage
Tiller number determines ear number and therefore yield; nitrogen is critical here and top-dressing (usually urea/CAN) is applied. To reduce stress coming out of winter and accelerate growth, foliar AminoWork and Power NPK for balanced nutrition provide support.
3. Stem Elongation Stage
Nitrogen demand peaks; trace elements (especially zinc) and amino acid support strengthen leaf health and growth. Foliar AminoWork improves stress resistance.
4. Heading and Grain Fill Stage
Nitrogen drives grain protein, and stress management drives grain fill. In this stage, where drought and heat stress are common, foliar amino acid application supports grain fill. For iron or trace-element deficiency, use FerroPlus.
Common Nutrient Problems in Wheat
- Zinc deficiency: the most critical issue; causes stunting and yield loss. Identified by analysis and corrected with a zinc program.
- Nitrogen shortage: pale colour, few tillers, low protein; managed with top-dressing.
- Iron/manganese deficiency: yellowing on young leaves; see our leaf yellowing guide for symptoms.
Wheat yield rests on correct base fertilization, adequate nitrogen at tillering, and trace-element management, especially zinc.
