Summary

Results from an experiment with maize (variety NEH 1151) at three plant densities indicated that normally favourable environmental conditions promoted tillering and it was difficult to maintain the desired tiller densities. The higher densities produced more vegetative dry matter but less grain than the lower densities. In a second experiment, where tillers were removed from the plants, there was no advantage because the remaining tillers grew larger to compensate for the removal. It is concluded that it is desirable to breed or select for non-tillering varieties where other management parameters can be controlled.
