To study the influence of α-tocopherol (α-TOC) and nicotinamide (NAM) on growth and physiological responses of Lupinus termis plant, field experiments were conceded at Experimental Station of National Research Centre, Nubaria Region, Behaira Governorate, Egypt. Three levels of α-TOC (1 mM, 2 mM, 3 mM) and NAM (1 mM, 5 mM, 10 mM) were applied as foliar spray. Growth measurements were performed at 75 days after sowing. Seed yield and yield attributes as well as seed quality were also determined at harvest stage. Foliar application with α-TOC and NAM significantly improved lupine plants in sandy soil in terms of growth, photosynthetic pigments, indole-3-acetic acid, seed yield, yield components and seed quality (oil%, carbohydrate%, phenolic compounds (mg/g) and flavonoid compounds (mg/g) and antioxidant activity). NAM treatments were more effective than α-TOC. 10 mM NAM was the most pronounced treatment. It is worthy to mention that α-TOC (2 mM) and NAM (10 mM) caused marked decreases in saturated fatty acids of seed oil accompanied by increases in unsaturated fatty acids, hence improving oil quality. The current research suggested that α-TOC and NAM as a foliar application increased lupine growth, seed yield and seed quality under reclaimed sandy soil.
