Response of faba bean to rhizobial inoculation and fertilization with micronutrients in sandy soil

ABSTRACT

A pot experiment was carried out to study the effect of rhizobial inoculation and micronutrients fertilization on nitrogen fiaxation and yield of faba bean grown in virgin sandy soil. Rhizobial in oculation and micronutrients fertilization either alone or in combination improved seed yield, total plant dry weight, module weight and N-content. Foliar application of micronutrients was more effective compared with the direct addition or soaking application particularly when a complete mixture of Mn, Mo, Fe and Zn was used. Generally, the deficiency of Mo and/or Fe showed negative effects on N2 fixation and plant growth as compared to Mn or Zn deficiency
