Two field experiments were carried out during two successive winter seasons at 2013 and 2014, in a private farm at Abuo-Hammad area, Sharkia Governorate, Egypt, to evaluate the integrated fertilization management i.e.
chemical fertilization (NPK), biofertilization (Rhizobium
leguminosarum. bv. vicieae, Glomas bagyarajii, Bacillus
circulans) with or without foliar applications of yeast extract
(Saccharomyces cereviseae) and micronutrients on enzymes
activity, nodulation status, growth characteristics, chemical
constituents, mycorrhizal infection (%) and yield of pea
(Pisum sativum L.) cv. Master B grown under loamy sandy
soil conditions. All estimated parameters were affected by
biofertilizers application, especially in combination with
foliar applied with yeast extract. The highest values of the
most studied parameters were recorded in combination
between biofertilizers with foliar application of
micronutrients and yeast extract.
