Irus study was aiming for the determination of some heavy metals (Co, , ,
Pb, Cd and Co) of soil and cucumber plant tissue, Plants were cultivated in pots under
greenhouse condition for two consecutive seasons using different mixed of drainage.
trl-treated, or-treated and ground water, Using (100% Tri-treated water) treatment,
significantly increased Pb and Cd in soil and plants tissue compared with other
treatments In soil and plants tissue were (2,90,2.81,1,92 and 2,01 mg/kg) respectively,
'.'vhile the highest value for Co (3,29 mg/kg) in soil was obtained after irrigation(100%
-irainaqe water) treatment compared with other irrigation treatments .while the highest
Co value in plant tisslJe(2,42 mg/kg) was obtained after using 100% di-treated water,
C" other the hand. the lowest concentration for heavy metal (Pb,Cd and Co in soil
and plant (0,93,0,91,1,08 ,0.93,0.90 and 1.09 mglkg)respectively were obtained after
using ground water only, However, high value for dry/fresh weight plant (19,66 %)
was observed when (100% ground water (G) treatment was used. The highest value
for cucumber yield (1,60 kg/plant) was obtained after irrigation with ground water (G)
control, the second rank (0,79 kg/plant with 75% (G) + 25% drainage water(R. The
lowest value for dry/fresh weighVplant (15,66%), and cucumber yield (0,40 kg/plant)
was observed when irrigated with (25% G + 75% 0) treatment. The highest Pb ,Cd
and Co concentrations(3,80,3.27 and 3.95 mg/kg ) respectively were obtained of tri-
treated water compared with others waters ( drainage .di-treated water and ground
water) Fina:!~I, it is possibly suggested that the use of drainage, tri ditreated water
could be utilizated for irrigating cucumber plants without hazardous some heavy metal
(Pb, Cd and Co) concentration in soil and plant tissue,
