Abstract: Two field experiments were conducted during two winter seasons of 2011 and 2012 at Nubareia Agricultural Research Station Farm on calcareous silt clay loam soil under drip jrrigaticn system to study the effect of adding K-humate (250 g fed"), rhizobia as well as foliar application with yeast and algae extract (each one at 500 g fed"), on yield and its components as well as chemical composition of faba bean (Vicia faba L. Giza 843) plants. Results obtained revealed that applying of K-Humate and rhizobia (Rhizobium leguminosarum), led to improve many of soil variables such as organic matter content, soil pH, Ee and available NPK, with superiority for the combined treatment of (KHumate +Rhi). Also the results indicated that, application of K-Humate, significantly increased all of the studied growth characters, i.e. plant height as well as dry weight of shoots. However, yeast did not show a clear trend for various studied growth characters. Moreover, addition of K-Humate in soil, as well as foliar application by yeast and algae extract significantly increased yield and its yield components. The plant pigments, i.e. chlorophyll a and chlorophyll b concentrations in leaves . significantly increased at both samples when the plants were treated with K-Humat, yeast, and algae extract. In shoots, N, P and K concentrations significantly increased with all studied applications. Results also showed that ail studied applications significantly increased some chemical compounds, i.e. total sugar at faba bean leaves as well as protein content.
