Abstract: A field trial was carried out during spring season of 2016 at the field experiment of field crops department, college of agriculture-university of Baghdad/AL-Jadiriya.The objective was to investigate the effect of seed priming and withholding water at certain growth stages on growth, grain yield and its components, quality properties,water consumption and water use efficiency of sorghum(sorghum bicolor(L.)Moench) variety Bhoth70.The nested design with three replicates was used, where blocks were specified for withholding irrigation water treatments, during plant growth stages until 50% of depletion of available water.They were: full irrigation(I1),withholding water at 5 leaves stage (I2),withholding water at the appearance of last folded leaf(I3),withholding water at 50% flowering (I4),withholding water at two growth stages I3 +I4 (I5) and withholding water at three growth stages I2+I3+I4(I6).Within each block, seed priming treatments were laid out. They were:Gibberllic acid (600mg L-1),Kinetin(100mg L 1),Ascorbic acid(30mg L-1) and un primed seeds (dry seed as control). the results indicated. All seed priming treatments increased the field emergence percentage compared with dry seeds with GA3 treatment giving the highest averages of field emergence (71.33%), plumule length (7.65cm), seedling dry weight (17.55mg), plant height (183.42cm). kinetin treatment achieved the highest value (11.38 cm) of radicle length , flag leaf area (284.88 cm) , flag leaf dry weight (3.36gm). *Part of M.Sc.thesis of the first author.
