The aim of this study is to contribute to the realization of the project, which relies on integrating fish farming into agriculture. It consists of evaluating the effect of irrigation with fish farming water on plant growth and yield of cultivated species, in order to minimize the use of chemical fertilizers. All parameters of water were analyzed: the potential of hydrogen (pH), conductivity (CE), calcium (Ca²⁺), sodium (Na⁺), nitrate (NO₃⁺), sulfate (SO₄^2-), magnesium (Mg²⁺), potassium (K⁺), and chloride (Cl^-). The analyses of potable and fish farming waters indicated that all studied parameters are balanced means that waters are appropriate for irrigation. In addition to analyzes of water, soil parameters were measured: the potential of hydrogen (pH), conductivity (CE), organic matter (OM), the mean weight diameter (MWD), chloride (Cl^-), sulfate (SO₄^2-), calcium (Ca²⁺), magnesium (Mg²⁺), limestone (CaCO₃). For the realization of our experience, we choose the tomato (Solanum Lycopersicum) as a corps. We planted the seeds in special seedling pots, divided into 03 sections: Section irrigated with potable water, Section irrigated with fish farming water, and the last section irrigated with potable water with the addition of chemical fertilizers. The three tests summarize that the plant irrigated with potable water plus the fertilizer has similar results to the plant irrigated by fish farming water. Moreover, Plant development is highly adaptive to environmental conditions. On the contrary, plants irrigated with potable water have slow growth and a low yield.
