Content and main results of the papers of this Special IssueEl-sherbeny et al. ( 2022) conducted an experiment on nitrogen fixation (NF) in an experimental farm with a drip irrigation system, at the Atomic Energy Authority, Inshas, Egypt, in order to measure the impact of efficiency symbiotic Bradyrhizobium sp. and asymbiotic Azotobacter sp. on NF, from air and soil, in the presence or absence of plant residues on the growth and yield of peanut plant. Bradyrhizobium sp. inoculation showed nearly the same levels of nitrogen derived from air (Ndfa) to those recorded with Azotobacter sp. in both the presence and absence of plant residue application through the two seasons. Results show that both possibility of NF of peanut and nitrogen uptake in the soil are enhanced by field J. Bech (*
