The field excrement was conducted in the agronomy farm of Gazala, Sharkia, Egypt to study the effect of power mix, citrine and super blue green biofertilizers on some biochemical contents of soybean shoots of (Giza111 and Crawford) varieties. The following results were recorded: - 1- All doses of biofertilizers increased dry weight content of shoots to both varieties of soybean. Giza111 variety recorded relatively greater values than those of Crawford variety. 2- The concentration of chl. a, chl. b and total chl. Of shoots soybean were increased by all treatments while decreased the concentration of carotenoids in shoots only at early stages of Giza111 variety, but increased of crawford variety at all stages of growth. 3- The percentage of total soluble sugars (reducing and non-reducing) in shoots of crawford variety were greater than those of giza111 variety and the highest increase of total soluble sugars was obtained by the foliar application of 0.25% and 0.5% super blue green biofertilizers. 4- All treatments were increased the concentration of soluble, insoluble and total nitrogen fractions in both varieties of soybean shoots at all stages of growth. 5- All doses of biofertilizers decreased the concentration of Na in shoots of both varieties of soybean, while they were increased the concentration of P and K at all stages of growth. 6- Fe, Zn and Mn contents were slightly increased by the application of biofertilizers at the early and second stage of growth, while they decreased values at the late stage of shoots growth. Conclusively, from the current results, it can be noticed that the application of all biofertilizers increased dry weight, photosynthetic pigments (chl. a, chl. b and carotenoids), the percentage of total nitrogen were increased either with all doses of biofertilizers in both varieties of soybean (Giza111 and Crawford). the highest increase of total soluble sugars was obtained by the foliar application of 0.25% and 0.5% super blue green biofertilizers especially in Giza111 variety. All micro and macro elements were increased (Na, K, P, Fe, Zn, Mn) except Na on all soybean vaterites. |
