- Intervention effect Water deficit during panicle development reduced grain yield of the pearl millet main shoot panicle.
- Intervention effect Removing the main shoot at panicle initiation was fully compensated by tiller grain yield in irrigated and water-stressed pearl millet.
- Intervention effect Compensation for the main shoot grain yield loss was only partial when the main shoot was removed at flowering.
- Mechanism Tiller compensation for main shoot grain yield loss, caused by water stress or removal, operated through more grains on the tillers.
- Mechanism Under water stress, the number of productive tillers increased, explaining tiller compensation.
- Mechanism With main shoot removal, both productive tillers and grains per panicle increased on the tillers.
- Mechanism The tiller compensatory mechanism plays an important role in overcoming pre-flowering water stress damage to the main shoot.
