AbstractThis experiment was conducted at a space of Biology Dept.,Education College, Kufa University, from the period of 28/12/2005 to 18/2/2006 to study the effect of watering with deferent water salinity (River water ; Mixed water , i.e. river water and drainage water at concentrations of Nerium dry leaf powder ( 0.0 ; 2.5 ; 5.0 ; 7.5 and 10.0 g/kg. soil) on emergence percentage and early growth of Wheat .The experiment included sowing Wheat seeds “ cv. Ipa 95 “ on pots with 24 cm. diameter and 12 cm. depth that filled with 3 kg. of Silty-Clay soil . Emergence percentage was measured after 10 days of sowing , and at 50 days from sowing growth parameters (plant height , leaf number , root length and its branches and plant dry weight) were measured . Completely Randomized Design (CRD) was used as factorial experiment with three replicates , Duncan’s Multiple Rang Test (DMRT) was also used to compare means at probably of 5%.Results showed that , watering with river water resulted in a significant increase in the measured growth parameters compared to mixed or deranged water . Nerium dry leaf powder of 2.5 g mixed with 1 kg . of soil had a significant effect on the measured growth parameters .On the other hand , the best values for the measured growth parameters , were obtained from the interaction between plants that watered with river water and the addition of Nerium dry leaf powder of 2.5 g/kg soil which produced 88.0% , 13.6 cm. , 7.0 leaf , 15.1 cm , 6.37 root and 987.3 mg/plant for emergence percentage , plant height , leaf numder , root length , root branch and plant dry weight , respectively , compared to 36.0 % , 7.8 cm. , 3.9 leaf , 5.17 cm. , 4.07 root branches and 372.0 mg/plant . Also , the use of mixed water with 2.5 g/kg soil of Nerium dry leaf powder on seedling emergence which was 86.0% .
