Response of wheat to biofertilizer inoculation under different sources and levels of nitrogen [electronic resource].

Includes references.

A pot experiment was conducted at experimental farm (Abo AIAkhdar clay soil), Faculty of Agriculture, Zagazig University to study the effect of organic and mineral nitrogen at rates of 50, 75 and 100 mg N kg⁻¹ and seed bioinoculation using Azotobacter chroococcum N-fixing bacteria as a fertilizer called Cerealine, and a mixture Azotobacter chroococcum and Azospirillium lepojerm N fIxers + Bacillus megatherium P-dissolving bacteria as a fertilizer called Nitrobien. The interaction effects between biofertilization, organic and chemical fertilizer sources and levels on wheat yield, chemical composition and uptake of nitrogen, phosphorus and potassium were studied. Results reveal that high of wheat straw yield and straw nitrogen uptake can be obtained with treatment of 100 mg N kg⁻¹ of chicken manure with inoculation by Nitrobien. The highest straw phosphorus and potassium uptake obtained under application 75 mg N kg⁻¹ of chicken manure and inoculation by Nitrobien. Tbe highest straw phosphorus and potassium uptake were ohtained under application 75 mg N kg⁻¹ of chicken manure and inoculation by Nitrobien. The highest phosphorus uptake by grain were obtained under application 75 mg N kg⁻¹ of ammonium sulphate without inoculation, while the highest potassium uptake by grain obtained under application of 50 mg N kg⁻¹ of chicken manure without inoculation.
