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.
