| Abstract | ||
| Two experimental trails were designed to quantify the response of nodulation, growth and yield and its components of faba been plants as well as nutrient content in seeds toward foliar spray twice of zinc (0.3% zinc sulphate), iron (0.6% iron sulphate) and molybdenum (0.05% ammonium molybdedate) under some bio-stimulants, i.e., inoculation with rhizobium and 10 kg humic acid/feddan. The experiments were conducted at the Farm of Sids Agricultural Research Station (ARC), Beni Swif Governorate, Egypt during two successive seasons (2013/2014 and 2014/2015). Number and dry weight of nodules/plant showed positive significant response to iron and molybdenum applicationas well as rhizobia and humic acid treatments comparing with control. The maximum values of these parameters were produced in plots under the effect of molybdenum followed by iron application in combined with bio-stimulants. Plant height, dry weight/plant, number of pods/plant, number of seeds/pod and grain and straw yields were recorded under the treatments of spraying 0.6% iron sulphate in combined with rhizobia inoculation plus humic acid. Higher nitrogen or protein content in seeds were produced under 0.3% zinc sulphate plus rhizobia inoculation plus humic acid, while, Fe and Mo application did not affect nitrogen content. Zinc or molybdenum applications decreased phosphorus content in seeds, while, humic acid enhanced P content. Potassium content was affected only by humic acid. Zn application inhibited Fe content and vice versa iron application decreased zinc content in seeds. Added Zn, Fe, and Mo increased their contents in seeds, respectively. Also, humic acid application improved macro and micronutrients in faba bean seeds. | ||
