This study was conducted to examine the effects of the foliar application of moringa and germinated fenugreek extracts on the growth and biochemical parameters of wheatgrass grown under saline conditions. Aqueous moringa extract (MLE) was used at concentrations of 1.25, 0.83, 0.62 and 0.31%, whereas fenugreek extract (GFE) was used at concentrations of 0.25, 0.20, 0.15 and 0.10%. Optimum germination conditions were investigated under normal and NaCl stress (2000 ppm) conditions. Exposure to saline stress significantly reduced seed germination and grass yield as well as shoot and seedling fresh and dry weights. Ideal germination conditions were MLE 0.31% and GFE 0.15%, resulting in increased growth traits compared with the other concentrations and control. Foliar application of MLE or GFE improved growth traits, total antioxidants, phenols, Ca, Mg, K, Mn, Cu, Zn and Fe in the presence or absence of NaCl. In addition, wheatgrass powder was used to replace wheat flour in developing biscuits at 5, 10 and 15% levels. Wheatgrass showed high feasibility for formulating nutrient-rich biscuits with acceptable sensory qualities. These findings provide useful information for enhancing the nutrients in biscuits, with potential use as a natural source of bioactive compounds in functional food products.
