From Effect of the timing of water deficit on growth, phenology and yield of pearl millet (Pennisetum glaucum (L.) R. Br.) grown in Sahelian conditions, by Winkel et al., 1997 Complete crop emergence occurred on 15 February and plants were thinned to a population of 3 plants m~2 at 15 DAE -> so, results per plant to be multiplied with 30.000 to get outcomes per ha and to be multiplied with 30 to translate g/plant to kg/ha Water regimes consisted of four treatments, a control irrigated throughout the study, and three stress treatments in which irrigation was withheld prior to flowering (from 30 45 DAE, treatment S30), during early flowering (45-60 DAE, treatment S45) and late flowering (60-75 DAE, treatment S60). Irrigation was applied by microsprinklers at a spacing of 1 x 1 m. Water applications were the same for all treatments except during the deficit periods. The control regime approximately simulated the natural rainfall regime of the region of Tanout, with a gradual increase of irrigation frequency and amount until flowering, and a tapering off towards the end of the season (Fig. 1). 72
