EFFECT OF FOLIAR MICRONUTRIENTS UNDER SOME BIOSTIMULANTS ON THE PRODUCTIVITY OF FABA BEAN (Vicia faba L.)
Year: 2016
Type: article
Abstract: Two experimental trails were designed to quantify the response ofnodulation, growth and yield and its components of faba been plants as wellas nutrient content in seeds toward foliar spray twice of zinc (0.3% zincsulphate), iron (0.6% iron sulphate) and molybdenum (0.05% ammoniummolybdedate) under some bio-stimulants, i.e., inoculation with rhizobiumand 10 kg humic acid/feddan. The experiments were conducted at the Farmof Sids Agricultural Research Station (ARC), Beni Swif Governorate, Egyptduring two successive seasons (2013/2014 and 2014/2015). Number and dryweight of nodules/plant showed positive significant response to iron andmolybdenum applicationas well as rhizobia and humic acid treatmentscomparing with control. The maximum values of these parameters wereproduced in plots under the effect of molybdenum followed by ironapplication in combined with bio-stimulants. Plant height, dry weight/plant,number of pods/plant, number of seeds/pod and grain and straw yields wererecorded under the treatments of spraying 0.6% iron sulphate in combinedwith rhizobia inoculation plus humic acid. Higher nitrogen or protein contentin seeds were produced under 0.3% zinc sulphate plus rhizobia inoculationplus humic acid, while, Fe and Mo application did not affect nitrogencontent. Zinc or molybdenum applications decreased phosphorus content inseeds, while, humic acid enhanced P content. Potassium content was affectedonly by humic acid. Zn application inhibited Fe content and vice versa ironapplication decreased zinc content in seeds. Added Zn, Fe, and Mo increasedtheir contents in seeds, respectively. Also, humic acid application improvedmacro and micronutrients in faba bean seeds.
