Nitrogen
Apply 30-40 kg N/ha prior to planting. This may be applied as a preplant broadcast application or banded through the planter, 5 cm below and 5 cm to the side of the seed. Side-dressing of nitrogen is only recommended if foliage shows nitrogen deficiency. Over-application of nitrogen will cause excess leaf growth, resulting in uneven maturity.
Phosphorus and Potassium
Test the soil to determine phosphorus and potassium requirements.
