plant

for nutrient solution and effluent fish water, respectively. The
highest value of fresh and dry weights of 215.88 and 26.36 g plant
-1
was obtained with a flow rate of 1.0 L min-1
and 2 m length of gully,
while, the lowest value of fresh and dry weights of 170.68 and 19.05 g
plant
-1
occurred at a flow rate of 1.5 L min
-1
and 4 m length of gully in
nutrient solution. On the other hand, the highest value of fresh and dry
weights of 217.18 and 23.72 g plant-1
was obtained at a flow rate of 1.0
L min
-1
with 2 m length of gully, while, the lowest value of fresh and dry
weights 163.46 and 15.99 g plant-1
was obtained at a flow rate of 2.0 L
min-1
with 4 m length of gully in effluent fish water.
Decreasing the fresh and dry weights of shoots with increasing the
flow rate from 1 to 2 L min
-1
and increased the length of gully from 2
to 4 m may be attributed to decrease in nutrient consumption rate.
These results agreed with those obtained by [27] who found that the dry
weight decreased with increasing the flow rate from 0.5 to 1.5 L hour-1
.
