Abstract

This investigation was carried out in a demonstrated field at Al-Ibrahimia district, El-Sharkia Governorate, Egypt, during 2014/2015 and 2015/2016 winter seasons to study the impact of three phosphorus levels (check, 15.5 and 31 kg P2O5/fad.) and five micronutrient spraying treatments [Zn, Mn, Fe, Zn + Mn + Fe and control (tap water)] on faba bean yield (Vicia faba L. cv. Giza 843) and seed protein content. The obtained results could be summarized as follows: Raising phosphorus level to 31 kg P2O5/fad., significantly increased number of pods per plant, number of seeds per pod and plant, as well as seed and stover yields per fad. Whereas‎, 100-seed weight and seed protein content were significantly decreased. However, plant height was not significantly affected by phosphorus levels. Micronutrients spraying reflected significant increase in seed yield and yield attributes. The foliar application of any of the following micronutrient treatments i.e. Mn, Fe and Zn + Mn + Fe had significant effect on seed yield per fad., while, micronutrient spraying treatments had insignificant effect on number of branches per plant and seed protein content compared with the control treatment. The interaction between the two factors had significant effects on yield and its components, where the highest seed yield per fad., (13.79 ardab) was achieved by addition of 31 kg P2O5/fad., with Mn foliar application (0.4 g/l).
