Two experiments were carried out in a greenhouse at the Experimental Farm of Faculty of Agriculture, Minufiya University, Shibin El-Kom, Egypt during the two growing seasons of 2021 and 2022 to study the influence of dried sewage rates [0, 5, 10  and 20% (w/sewage: soil)], irrigation with magnetized water and their interactions on some vegetative growth parameters, plant water relations and membrane stability (permeability), photosynthetic pigments, some biochemical compositions i.e. (total soluble sugars, total protein, total free amino acids, proline, activity of some enzymes, some nutrient minerals, yield and its components of cowpea (Vigna unguiculata subs. punguiculata L. cv. Giza7) and rocket (Eruca sativa L.) plants as well as behavior some heavy metals and their effect on human health. Plant samples were taken after 40 and 60 days from sowing.
