Other claims from this paper (11)
- Intervention effect Water-regime-by-N-rate interactions were not significant for root dry weight, length and average radius in either environment.
- Intervention effect Water-regime-by-N-rate interactions were not significant for root/shoot ratio and N influx in either environment.
- Observation Root weight and root length differed among corn genotypes.
- Association The corn genotype with the greatest amount of roots deep in the soil had the highest grain yield increase with irrigation.
- Intervention effect Root mass and root length of corn were greater in the zero N treatment than in the applied N treatments.
- Intervention effect Severe water stress reduced corn root mass and length in the greenhouse.
- Intervention effect Moderate water stress in the field significantly increased corn root length.
- Association Water use efficiency of corn was positively correlated with root mass and length in the greenhouse.
- Intervention effect Water regime did not affect N influx of corn in either experiment.
- Association The authors conclude that corn response to irrigation will be altered depending on root morphology.
- Recommendation The authors recommend considering the root system when selecting N efficient and/or drought tolerant corn genotypes.
