Effect of using garlic and lemon peels extracts with selenium on Vicia faba productivity

Several agricultural practices produce wastes rich in some useful compounds. In this research, two types of wastes (i.e., garlic and lemon peelings) were chosen and used to prepare mixtures of these peels alcoholic extract with a certain concentration of selenium, either alone or in combinations treatments. Faba bean seeds (Vicia faba L. cv. Sakha 3) were cultivated in winter season of the year 2019 on a silty clay soil after soaking in these mixtures for 24 h. Some vegetative growth parameters such as fresh and dry weights, plant length, as well as N, K, phenols and flavonoids contents were determined during different physiological growth stages of Vicia faba, in addition to determine the leaf area and number of pods per plant at the flowering growth stage. Besides of pods and seeds weight, and seeds content of N, K, Se, protein, phenols and flavonoids were also determined after harvesting. Obtained results showed that soaking seeds in the studied extracts significantly increased the weight of pods and seeds as compared to the control treatment. Moreover, the soaking process increased the percentage of antioxidants in the produced seeds of Vicia faba as compared to the control treatment. This finding highlights the benefit of such soaking process to foods rich in antioxidants that increases immunity and resistance of human against widespread diseases.
