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.
