The world’s population increases dramatically and it’s expected to reach nine billion people by 2050.
In Egypt, about two million people are add-ed each year to the population (Shalaby et al., 2011).
In addition, 97% of Egyptian land is desert and with limited water re-sources (Abdalla et al., 2023).
Hence, it’s obligatory to face the growing population by increasing the cultivated area with strategic
crops as wheat and barley and also expansion in reclamation of desert lands.Barley is considered one
of the premier and most important cereal crops for its earliness and tolerance of each drought and salinity (Mariey et al., 2018; Habiba et al., 2021and Güng?r et al., 2022). The cultivated area of barley around the world is estimated with 46.9 million hectares giving about 141 million tons annually (FAO, 2020). El-Khalifa et al. (2022) stated that barley is indispensa-ble crop in Egypt and occupy 76.9 % of newly reclaimed area. The productivity of barley in Egypt reached 108,000 tons in 2019 and it’s expected to increase more and more in the future (Mohamed et al., 2021). Barley can be utilized as animal feeding, for manufacturing of bread and many healthy foods (El-Seidy et al., 2019; Kumar et al., 2020; Aly et al., 2021).
One of the suggested solutions for overcoming wheat shortage in Egypt is addition barley to wheat flour to obtain bread (Abdalla et al., 2023).
