6
yield increase
Agromaster® with 60% coated nitrogen with eqo.x technology increased total yields and NUE.
Gommersheim, Germany 2023
6
Key Conclusions
- Higher yields – up by 6%, extra 2.6 mt/ha vs Grower Practice with Agromaster®M> at 100% N rate and an extra 0.7 mt/ha with Agromaster® at 80% N rate
- Higher NUE – Agromaster® provides higher nitrogen use efficiency – up to 69 kg of potato per each kg N applied
- ROI – up to +1162 €/ha at 100% N rate and +340 €/ha at 80% N rate
Objective
To evaluate the performance of Agromaster® with eqo.x® release technology (33.5-0-0, 2-3M, 60% coated N) in potato, in 2 different dose rates in comparison to grower practice
