摘要：Two field experiments were conducted to eval-uate the performance of faba bean varieties(Giza 843, Sakha 4, Nubaria 1)particularly, growth stages, yield and yield components under potassium fertili-zation and amino acids foliar application(Control (distilled water), K(as a foliar),K(Soil application), Amino acids, K(as a foliar)+Amino acids, K(soil application)+Amino acids). The results showed that all characters of faba bean such as plant height,total Chl.content, yield and yield components were sig-nificantly increased by application of K as foliar +Amino acids treatment compared with control in both seasons respectively, except the traits of straw yield(Kg fed')and No.of seeds plant-l.The varie-ties were significantly differed at all studied traits where, Giza 843 was superior at biological yield, seed yield, straw yield, No.of branches plant, No. of pods plantl, No.of seed plantl, weight of pods plant', weight of seeds plant'and weight of 100 seeds(g), while, Nubaria 1 recorded the highest value of plant height(cm) and total Chl.content with significant differences. Generally, the results showed that the interaction between potassium fertilization and amino acids as foliar application and faba bean varieties recorded significantdifferences in yield and yield components in both seasons. It can be con-cluded that application of K as foliar along with Amino acids treatment could be recommended for the highest grain yield of Giza 843 under delta con-ditions.
