e0“The responses to water deficit and two levels of nitrogen (0 and 200 kg N.ha-1) were assessed here for agronomic and physiological traits for potato genotypes UNICA, Achirana-INTA, and CIP397077.16”
e2“Despite this, the tuber yield and total biomass reduction of around 50 % for all genotypes could be alleviated with N application”

Other claims from this paper (6)
- Intervention effect Drought greatly reduced nitrogen use efficiency in all potato genotypes, nearly to zero.
- Intervention effect Drought reduced tuber yield and total biomass by around 50 % in all potato genotypes.
- Observation NDVI, chlorophyll content (SPAD) and canopy cover are good indicators for predicting nitrogen deficits and detecting early drought stress in potato.
- Observation UNICA was the most efficient potato genotype at using soil nitrogen and tolerating drought.
- Observation Achirana-INTA was the potato genotype most affected by drought in terms of NUE.
- Recommendation The authors suggest that maximum fertilizer use efficiency can be obtained with low N rates under well-watered conditions.
