  abstract = {{S}everal studies conducted under high input conditions have indicated little susceptibility of pearl millet to water deficit untill early grain filling, because the losses in main shoot production were fully compensated by increased tiller fertility. {T}he present study assessed the impact of water deficits at three development stages : prior to flowering ({S}30), at the beginning of flowering ({S}45), and at the end of flowering ({S}60) in pearl millet grown in experimental conditions similar to {S}ahelian farming conditions. {I}t included a control irrigation treatment simulating the natural distribution of rainfall throughout the cropping season. {B}oth biomass production and grain yield were severely reduced by {S}30 and {S}45, while {S}60 had no effect. {I}n {S}30 and {S}45, the flowering of tillers was delayed or totally inhibited. {I}n both of these treatments, the low number of productive tillers did not compensate for damage to panicle initiation and flowering of the main shoot. {A}ll treatments maintained green leaves on the main shoot during the grain filling period, and in {S}30 leaf growth recovered from mid-season drought. {T}hese results illustrate how pearl millet mostly escapes drought by matching its phenology to the mean rainfall distribution in the {S}ahel. {I}n the case of mid-season drought, some late productive tillers and the maintenance of green leaf biomass of the main shoots limited, but did not overcome, the yield losses. {T}his study stresses the importance of agro-ecological conditions in control treatments, particularly the water regime and crop density, when assessing crop drought resistance.
