e1“Potato is often produced by adopting high nitrogen (N) external inputs to maximize its yield”
e2“tuber chemical composition of cv. Bellini”
e5“regardless of year and as compared to N0 and N280, the supply of 140 kg N ha−1 also ensured the highest yield and an intermediate value of the nitrogen use efficiency (59.1 t ha−1 and 37.1 kg tuber dry weight kg N−1, respectively)”
e3“a low nitrate amount”
e4“(16.6%, 634-3.31-0.61 and 0.93 g kg−1 of dry matter, respectively)”

Other claims from this paper (7)
- Intervention effect N140 improved leaf photosynthesis rate and SPAD readings compared with the other N rates.
- Intervention effect The 140 kg N ha-1 supply gave the highest potato yield, compared with N0 and N280.
- Intervention effect The 140 kg N ha-1 supply gave an intermediate nitrogen use efficiency, compared with N0 and N280.
- Intervention effect The 140 kg N ha-1 supply gave tubers with high dry matter and starch.
- Intervention effect The 140 kg N ha-1 supply gave tubers with high total polyphenols and ascorbic acid.
- Association An interaction between N fertilisation rate and year was observed for potato.
- Recommendation A conventional N fertilisation rate of 280 kg ha-1 is unnecessary for potato from agronomic and qualitative standpoints.
