Pea nitrogen management and nutrient requirements

Pea cultivation requires precise nitrogen management, with trials (2019–2021) showing no significant yield differences across N rates from 0 to 200 kg/ha. Phosphorus and potassium are vital for root development, disease resistance, and storage quality, with optimal levels depending on soil type and P levels (20–75 kg P₂O₅/ha). Boron supports kernel formation, while lime improves moisture retention and nutrient availability. Split fertiliser applications aligned with growth stages and soil-specific CEC and clay-humus content enhance nutrient use efficiency. Small-scale trials are essential for evaluating new fertilisers, with long-term monitoring critical to assess yield and quality outcomes. Over-application of nitrogen offers no yield benefit and risks early salt damage. Recommendations must be tailored to soil conditions and crop history.
