Summary

Reducing the leaf areas of different maize hybrids at the time of female flowering resulted in a reduction of up to 70–90 g/plant of grain yield, with a parallel deterioration in the health of the stalk pith (due to infection by Fusarium sp.) and an increase in lodging. However, beyond a certain limit defoliation caused a loss in fertilization and a further decline in grain yield, which was accompanied by an improvement in the health of the pith and less lodging. There were considerable differences in the reactions of six genotypes to the defoliation treatments.
