Salinity and metals have a strong impact on plants. This study was conducted to evaluate the impacts of salinity and selected trace metals on muskmelon ( Cucumis melo L. ) growth, yield, and uptake grown in horizontal channels using a hydroponic system established at a model greenhouse at An-Najah National university. Plants were subjected to four salinity treatment including: 0 (control), 1000, 3000, 7000 ppm of NaCl . while three metals treatment were used including: 0, .1, .2 ppm of Cd, Cr, Cu, Zn. Data of plant height, number of leaves, and fresh and dry weight was taken. The uptake of NaCl was analyzed using electrical conductivity, and the uptake of metals was analyzed by ICP-MS.High concentrations of salt and metals cause a significant reduction on melon height and number of leaves. The weight of several melon parts was increased after salinity and metals treatment upto 3000, and .1 ppm of salt and metals, respectively, and start to decline at higher concentration this could be due to a nourishment effect up to certain level, and toxicity effect at higher concentrations. The uptake of salt and metals was increased with the increase of concentration.
