Response of Faba Bean to Foliar Spraying with Chelated Iron under different Nitrogen Fertilization Treatments in Sandy Soils

: Two field experiments were conducted during 2019/2020 and 2020/2021 seasons at El-Qasasin district in Ismailia Governorate to study the effect of four nitrogen fertilization treatments namely 20, 40, 60 and 40 Kg N/fad plus spraying with 1% urea as well as three concentrations of chelated iron (12.5% Fe) as foliar spraying namely tap water (control), 750 and 1500 ppm on yield, its components and quality of faba bean ( Vicia faba L.) Nubaria 3 variety in sandy soils of Ismailia Governorate. Plant height, number of branches and pods per plant, seeds number per pod, weight of pods and seeds per plant, hundred seed weight, seed and straw yields per fad as well as seed crude protein percentage of faba bean were significantly increased by raising nitrogen fertilization rate up to 60 Kg N/fad, which also exceeded significantly the treatment of 40 Kg N/fad plus spraying with 1% urea. Increasing chelated iron concentration as foliar spraying up to 1500 ppm statistically increased all aforementioned characters. The interaction between nitrogen fertilization treatments and foliar spraying with chelated iron affected significantly all aforementioned characters. The highest values of these characters produced from faba bean plants received 60 Kg N/fad and sprayed with 1500 ppm chelated iron.
