Abstract

A field experiment was carried out in saline sandy clay soil of a private farm at village 7, Gelbana (Sahl El-Tena plain) during two successive winter seasons of 2006- 2007 and 2007- 2008, to study the effect of different forms (ammonium nitrate (AN), ammonium sulfate (AS) and urea (U) at different rates (i.e., 70, 45 and 35 kg N/ fed) each alone and /or in combination with bio-fertilizer on faba bean productivity.
Results revealed that the applied fertilization treatments led to increase available macro and micronutrient soil contents. Such favored effect was reflected on plant nutrient contents, protein content, yield and its components and were significantly increased. In this connection, it could be deduced that urea fertilizer was of the highest effect, whereas AN was of least effect, while AS resulted in a moderate effect. Also, bio-fertilizer could partially substitute a considered portion of the mineral nitrogen. Since, bio-fertilization had been proved as an approach quite enough to improve plant quality, reduce the mineral nitrogen cost, as well as they are environmentally safe and eco-friendly.
