Abstract

The plant and fish growing system has recently come under the spotlight as a form of modern
agriculture that serves both scientific and economic objectives as Egypt looks to increase water
exploitation. An option for boosting irrigation water productivity in permaculture under the
restrictions of limited water supply is the integration of fish and crop production in an aquaponics
system. The results of this study showed how the characteristics of sandy soil, vegetable production,
and soil infiltration affected the water quality while recycling aquaculture (catfish) water for irrigation.
The okra growth quality Measurements showed that the crop produced in pots receiving 50% of the
suggested levels of NPK and irrigated with catfish culture water, was of the highest quality. According
to the study's findings, using aquaculture water rich in microbes and phytoplankton to irrigate
vegetables and as a soil fertilizer to partially substitute synthetic fertilizers can help to maintain a
balanced soil ecology with thriving crops. The findings showed that irrigation with aquaculture water
improved okra growth and output through enhancing soil health, which in turn increases productivity
of yield and water use efficiency.
