Enhancement of the growth and phenolic content of Faba bean (Vicia faba L.) by applying some biofertilizer agents

Abstract

Some microorganisms, i.e., Rhizobium leguminosarum var. faba, Aphanocapsa albida and Laurencia obtusa, were applied in pots to enhance the growth of faba bean (Vicia faba L.) plants. The individual and combined microorganisms applications significantly increased plant height and number of  leaves at the early growth stages. Ninety days after planting, all the treatments significantly enhanced the plant growth parameters. Laurencia obtusa + Aphanocapsa albida increased the whole plant length, dry weight, total phenols content and nitrogen content by 46.3%, 96.5%, 315% and 86% respectively. However while the combination between the three microorganisms increased whole plant fresh weight by 56.0% in comparison with control.
