| Two field experiments were conducted at Faculty of Agriculture farm, Al-Azhar University, Nasr City, Cairo, Egypt, during 2016/2017 and 2017/2018 seasons, for evaluating the effects of phosphate bio- fertilization (mycorrhizal fungi,phosphorine and Without inoculation), two sources of phosphorus fertilizers (super phosphate, rock phosphate and without phosphate) and humic substances (humic acid, fulvic acid and without humic substances) as well as their interactions on yield, yield components and nutrients uptake of barley cv. Giza 123. These experiments contain 27 treatments; a split split plot design with three replicates. The obtained results showed that the bio-fertilization were significantly increase of yield, yield components and nutrients uptake (nitrogen, phosphorus and potassium) compared without inoculation, it is worth mentioning inoculation Mycorrhizal fungi was superior to Phosphorine;inoculation Mycorrhizal fungi were significantly increase of yield components, phosphorus and potassium uptake by plant; phosphorus solubilizing bacteria play role in phosphorus nutrition by enhancing its availability to plants through slow release phosphorus from inorganic and organic soil by solubilization and mineralization. It is interesting to say that the applied phosphate source were significantly increase of yield, EFFECT OF BIO-FERTILIZER, PHOSPHORUS SOURCE280 yield components and nutrients uptake (nitrogen, phosphorus and potassium) compared without phosphorus, it is important to remember calcium super phosphate was superior to rock phosphate; the positive affect of super phosphate on yield behavior solubility nutrients also, absorbing various nutrients. The applications of humic substance were significantly increase of yield and nutrients uptake (nitrogen, phosphorus and potassium) compared without humic substance, additionally humic acid caused a significant increae grain, straw yields and nitrogen, phosphorus and potassium uptake by barley plant. Generally, from these results it can be concluded that the application of Mycorrhizal fungi, super phosphate and humic acid could be used as a complementary for mineral fertilizers to improve yield and nutrients uptake by barley plant. | ||||
