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.
