Experimental treatments
| Treatment 1 | Treatment 2 | Treatment 3 | Treatment 4 | Treatment 5 | Application rate, kg per ha | Application method |
|---|---|---|---|---|---|---|
| Control (without fertilisers) | NPK 10-26-26 | Acron NPK 16-16-16 | AN | UAN-32 | P30K30 + N45-60 | Pre-sowing, the 4-5 leaves stage and boot stage |
Field trials
Yield, t per ha
Acron NPK and UAN-32 contribute to yield growth due to better nutrition in autumn and high performance of liquid nitrogen as a supplement
