Abstract Background Garlic extract is a highly nutritive value extract; it contains large number of important enzymes and more than 200 biochemical compounds such as antioxidants and vitamins. Ascorbic acid and nicotinamide are considered as antioxidants and also known as growth-regulating compounds that influence different physiological and biochemical processes in plants. Methodology A field experiment was conducted in sandy soil during two successive seasons of 2015/2016 and 2016/2017 at Research and Production Station, National Research Centre, El-Nubaria Province, El-Behera Governorate, Egypt. The objective of this investigation was to study the effect of foliar application of garlic extract (5%), ascorbic acid (200 ppm) and nicotinamide (50 ppm) compared with tap water on growth, some biochemical aspects, yield, yield components and some chemical components of three faba bean cultivars (Vicia faba L, cv., Nubaria-1, Nubaria-2 and Giza-843). Results The obtained results showed that Nubaria-1 was superior to Nubaria-2 and Giza-843 in all growth and yield criteria in the growing seasons except plant height was superior in Nubaria-2. Foliar treatment of garlic extract had the superiority effect in all characters of growth and yield and its components, and consequently increased significantly all yield criteria of Nubaria-1 cultivar. Data clearly showed that the effect of different treatments caused marked increases in photosynthetic pigments, indole acetic acid, phenolics, carbohydrate constituents, free amino acids and proline contents of Nubaria 1 cultivar which was sprayed by garlic extract at 5% followed by nicotinamide and ascorbic acid, respectively. Conclusions In general, the current research suggested that garlic extract at 5% as a foliar application increased the quantity of faba bean cultivars grown under sandy soil conditions. Therefore, garlic extract at the rate of 5% and Nubaria1 encourage the farmers to use of garlic extract to give promising seed yield under reclaimed sandy soil.
