The lowest values of plant consumption were found at 4 m length
of gully and the highest values were found at 2 m length of gully. This
may be due to the number of plants in case of 4 m length as compared
with those of 2 m length. Worthy to note that pumping either nutrient
solution or effluent fish water to the growing gullies was adjusted at 1
min pumping and 4 m rest.
