- Intervention effect Low nitrogen reduced developing-kernel nitrogen 16% to 70%.
- Intervention effect Low nitrogen reduced developing-kernel carbon 8% to 50%.
- Intervention effect Low nitrogen caused yield losses of 43% to 52%.
- Intervention effect More carbon accumulated as starch under deficient nitrogen.
- Intervention effect Nitrogen treatment did not affect cob total free amino acid or soluble protein concentrations.
- Intervention effect Nitrogen treatment influenced cob free amino acid composition.
- Intervention effect Low nitrogen reduced glutamine in apical kernels 75% at silking.
- Intervention effect Low nitrogen reduced asparagine in apical kernels 57% at silking.
- Intervention effect Low nitrogen reduced glutamine in basal kernels 36%.
- Intervention effect Low nitrogen reduced asparagine in basal kernels 31%.
- Association Free amino acids in cob and kernels responded less to nitrogen at 21 DAS than silking.
- Mechanism Authors attribute low-N grain production more to assimilate composition than carbon availability.
