Abiotic stresses such as drought and salinity severely affect the mineral nutrients and protein level of plants. Current study was conducted on two Moringa species M.oleifera and M.peregrina inside glass house, using three factorial arrangement in Randomized complete Block Design (RCBD) to investigate how different levels of drought (2, 7 and 14 days) and salinity (0, 10, 25, 35, 45 and 60% ) impact the level of Nitrogen (N), Phosphorus (P), Potassium (K), Iron (Fe) and total proteins in the leaves of Moringa species. A dynamic decline in both nutrients and proteins contents were reported in both species with increasing interval of drought and concentrations of salinity. Most remarkable decline for both nutrient (N, P, K and Fe) and total proteins in both species were reported at drought interval of fourteen days and salinity concentration of sixty percent. The current study concluded that abiotic stresses such as drought and salinity significantly hampered the uptake of important nutrients in addition to metabolic activities involved in the synthesis of proteins.
