- Intervention effect Variable rate nitrogen in high yield potential zones increased total potato yield by 4.6 Mg ha-1.
- Intervention effect Variable rate nitrogen in high yield potential zones increased marketable potato yield by 4.6 Mg ha-1.
- Intervention effect Variable rate nitrogen in high yield potential zones increased US No. 1 potato yield by 4.8 Mg ha-1.
- Intervention effect Six fields had significantly larger total tuber size under variable rate nitrogen in high yield potential zones (+10 g tuber-1).
- Intervention effect Six fields had significantly larger marketable tuber size under variable rate nitrogen in high yield potential zones (+8 g tuber-1).
- Intervention effect Six fields had significantly larger US No. 1 tuber size under variable rate nitrogen in high yield potential zones (+11 g tuber-1).
- Intervention effect Lower nitrogen rates in low yield potential zones caused no yield decrease.
- Association Nitrogen use efficiency was inversely correlated with N rates.
- Intervention effect Average NUE was 25 kg ha-1 greater under variable rate nitrogen than under traditional N management.
- Intervention effect Higher N rates increased potato productivity in high yield potential areas.
