To achieve that was studied the effect of
source of nutrients (effluent fish water and nutrient solution), flow rate (1.0, 1.5 and 2.0 L min-1) and length of gully (2,
3 and 4 m) on the following parameters: nutrient uptake, dry weight and NO3-N content in plant. The obtained results
indicated that the fresh and dry weight of shoots increased in nutrient solution over those of effluent fish farm. The
fresh and dry weight of shoots decreased with increasing the flow rate and the length of gully.
