Abstract EN

This research was conducted to study the effect of rice husk addition as an organic matter onthe physical and chemical properties of salinity soils and the growth of millet (Panicum meliaceumL1) and the possibility of improving its productivity1 The experiments was conducted in plasticcontainers where the husk was mixed with the soil using different percentages (0% , 2% , 5% ) of soildry weight1 Afterwards, milts was planted taking into account its water needs1The experiment was ended after the end of the growth session and measurements for soilchemical properties were taken which is represented by the electrical conductivity, which has beenreduced by the additions.

Where it was reduced from (10.25) ds.

m-1 with no addition to (3.9) ds.

m-1with (5% ) addition, also, the (pH) levels were reduced by the additions1 Also, cation exchangeablecapacity was increased from (18.25) cmol.

kg-1 with no addition to (20.20) cmol.

kg-1 with (5% )addition1 Furthermore, the organic matter was increased from (019% ) with no edition to (4% ) withlevel (5% ) addition1 also, the physical properties of the soils was measured which is representedby water conductivity which has been increased to (8) cm.

h-1 and the apparent density which hasbeen decreased to (1, 27) cm.

h-1 and the average of weighted diameter to (0.72) mm.

and the soilresistance to penetration was decreased to (119) kPa with (5% ) addition of husk as an organic matter1Also, some characteristics of milt were measured such as plant height, holds feed green protein, which all improved with the increment in the addition of This research was conducted to study the effect of rice husk addition as an organic matter onthe physical and chemical properties of salinity soils and the growth of millet (Panicum meliaceumL1) and the possibility of improving its productivity1 The experiments was conducted in plasticcontainers where the husk was mixed with the soil using different percentages (0% , 2% , 5% ) of soildry weight1 Afterwards, milts was planted taking into account its water needs1The experiment was ended after the end of the growth session and measurements for soilchemical properties were taken which is represented by the electrical conductivity, which has beenreduced by the additions.
