Results

 

  • Agromaster® increased onion yield by 3 MT/ha.
  • Thanks to the controlled release of nitrogen, Agromaster® provides a higher Nutrient Use Efficiency (NUE) – an extra 5.7% compared to the grower practice, calculated as partial factor productivity (PFP).
  • Onion yield was higher with only 2 applications of Agromaster®, compared to 4 applications as in the grower practice. Less quantity to be handled per ha, while providing the same level of nutrients.
  • Agromaster® provides a positive return on investment (ROI): an increase of €381/ha.
