| Treatment 1 | Treatment 2 | Treatment 3 | Treatment 4 | Treatment 5 | Application rate, kg per ha | Application method |
|---|---|---|---|---|---|---|
| Control (without fertilisers) | NPS 20-20-14 | Acron NP 22-15+17SO3 | AN | UAN-32 | N66P45 + N60-90 | Pre-sowing and the 4-5 leaves stage |
Field trials
Yield, t per ha
NPK and UAN-32 contribute to stable yield growth due to improved nutrient efficiency
