Field experiment was conducted at the Hartha Research station .Agricultural College ,to study the effect of disking and addition of conditioners on plant consumptive water use in silty clay soil topic torrifluvent .The water table depth was 1.25m from the soil surface .Soil disking coded as follow :Without disking )D0),one time disking (Dl) ,Two time disking (D2),&four time disking(D3).The conitiationers were a Manure residuals at there levels ;zero level(C) levels 2% (OM1), levels 4% (OM2)of soil dry weight (b) : Bitumen emulsion at three level: zero level(C),0.5% level( BIX 1% level( B2), of soil dry weight.

The addition of Conditioners has resulted an increase in consumptive water use and water use efficiency, with take the maximum value was revealed in the (OM2,Dl).

The soil disking for one time interacted an increase in the consumptive water use and efficiency of plant.

The interaction between disking and conditioners gave the highest consumptive water use vales increase as the plant highest growth increase up to the flowing stage where the values wear recorded.
