Response of Soybean Plants to Mitigation of Irrigation Water Salinity by Salicylic and Ascorbic Acids

Abstract

Soybean (Glycine max L.) is widely cultivated for its edible bean, which has many uses. Soybean is the most important protein source for animal feeding and human food. Among the legumes, soybean is valued for its high protein content (38-45 %), also soybean seed contains 18-19 % oil (Livestock's long shadow, 2016).Soybean is a globally important crop that provides protein and oil for a wide array of products. Soybean seed is made up of crudely 40 % protein, 20 % oil, 35 % carbohydrate and 5 % ash (Soares et al., 2008).Total cultivated area of soybean in the world in 2018 was about 123.5 million ha which produced about 352.6 million tons, while in Egypt, the cultivated area was about 15000 ha produced approximately 45000 ton from dry seeds (FAO STAT, 2018). Soybean is very sensitive plant to drought and salinity conditions during vegetative and reproductive growth. Since soybean is classified as dehydration-sensitive species that require ARTICLE INFO
