Title
Dry Matter Accumulation in Maize in Response to Defoliation1
P. N. Egharevba; R. D. Horrocks; M. S. Zuber Agronomy Journal 1976. doi:10.2134/agronj1976.00021962006800010011x
Other claims from this paper (8)
- Intervention effect Defoliation within 30 days after silking significantly reduced total accumulated dry matter of maize compared with no leaf removal.
- Intervention effect Complete defoliation reduced maize yield by 6.4 to 82%, more than partial defoliation.
- Intervention effect Partial defoliation decreased maize yield by 1.5 to 32.7%.
- Intervention effect Severe leaf loss from silking to at least 10 days after 50% silking decreased maize grain yields because of fewer kernels.
- Intervention effect Removing all leaves 10 days after silking greatly reduced the number of kernels by 62.3%.
- Intervention effect Complete and partial leaf removal after silking affected kernel number considerably less, with an approximate decline of 20%.
- Association Yield decreases associated with less severe leaf loss or with loss 20 days or more after 50% silking were largely related to a decline in kernel weight.
- Intervention effect Removing all leaves above the ear did not significantly differ in effect from removing all leaves below the ear.
