Bayoumi, M. A. 1 and T. A. Selim( 2012). Effect Of Nitrogen, Humic Acid And Bio-Fertilization On Productivity And Quality Of Faba Bean Under Saline ConditionJ. Soil Sci. and Agric. Eng., Mansoura Univ., Vol. 3 (8): 829 - 843
Abstract: Two field experiments were conducted during 2010/2011and 2011/2012 seasons in saline soil in Galbana Village, Sahl- El Tina (North Sinai), Egypt to study the efficiency of nitrogen, (N) fertilizers or Humic acid either separately or in combination with (N) as well as humic acid associated with Bio- and N fertilization on yield and yield components of two Egyptian faba bean (Vicia faba L.) varieties namely Giza 716 and Sakha 3. Chemical composition, seed quality and some chemical properties of soil were also investigated. The results show that the characters of faba bean plants such as, plant height (cm), 100–seed weight (g), seed yield/plant (g), seed yield (ardab/ fed) and germination %, shoot and radical length (cm), fresh and dry weight of seedling (g), electrical conductivity for seeds (EC) and chemical composition of seeds (Protein and carbohydrate content as %) were significantly by application of the different treatments compared to the control treatment. The Macro elements (N, P and K %) and micro elements concentration (Fe, Mn, Zn and Cu) in seeds and stem were significant increased due to application of the different treatment when compared to the control treatment. Also, the results showed that the treatment of (Humic acid + Bio + N) gave the higher value of seed yield/ plant (62.0 g) compared to control (39.1 g) as well as germination percentage were improved also by application of (Humic acid + Bio + N) (81.0% and 76.7%) compared to treatment control (62% and 59%) in Giza 716 and Sakha 3, respectively. Concerning some chemical properties, the results show that the values of pH of the soil was decreased (8.0 ppm) due to application of humic acid + N. While the available manganese was increase in soil when this treatment was Also , Application of different treatments enhanced the availability of macro elements such as ( N, P and k), maicro elements (Fe, Zn, Mn and Cu) under studied soil.
