Abstract :Two field experiments were carried out in sandy soil of the Experimental Farm of the National Research Center, Nubaria District, EL-Behara Governorate, Egypt, during the two winter seasons of 2008/2009 and 2009/2010. The aim of the study was to investigate the effect of foliar application of urea (U) at ( 0 and 5g/liter) and potassium dihydrogen ortho-phosphate (PDO) at (0, 2.5, 5 and 10 g/1itre) on faba bean yield and its components (cv. Giza-461) as well as some chemical constituents. Spraying faba bean plants with 5g/L urea significantly increased plant height, number of pods/ plant, seed yield/plant as well as biological yield per faddan compared with the untreated control. Potassium dihydro-gen orthophosphate (PDO) foliar application significantly increased all the yield parameters compared with control. Spraying faba bean with (5g/L U + 2.5g/L PDO) recorded the highest number of pods per plant (7.00) and seed yield/ plant (11.57g). The highest N, K and Fe contents in seeds of faba bean were obtained when the plants were sprayed with (5g/L PDO), while the combined application of (5g/L U +5g/L PDO) produced the highest values of Zn and Mn in seeds.Keywords : yapraktan uygulama, potasyum dihidrojen ortofosfat, bakla, verim, tohum kalitesi
