Fertiliser type and placement effects on crop establishment, grain yield and water use efficiency on calcareous soils locations
Aims

To determine the impact of different fertiliser products and placement relative to the seed on crop emergence, crop WUE and grain yield.

Key messages
  • Applying MAP with the seed at sowing resulted in a 25% increase in plant emergence compared to using DAP at Piednippie.
  • Applying MAP at sowing resulted in higher grain yields and better water use efficiency (WUE) in plots which had high seeding rates at Nunjikompita.
  • In combination with a high seeding rate, a blend of DAP and triple super phosphate (TSP) applied at sowing at Piednippie and Nunjikompita (plus urea) resulted in grain yields which were closer to the crop yield potential than the control.
