Modification of Soil Environment Through Straw Application Versus Azospirillim spp. Inoculation
Effect of straw amendment on development of wheat plants inoculated with Azospirillum spp. and/or N-fertilized was investigated under field conditions of arid zones. Irrespect of any fertilization treatments, incorporation of straw into soil supported better growth of plants. Grain and dry matter yields increased with 8–12 % and 15–37 %, depending on fertilization treatments, respectively in absence of straw. Such increases amounted to 25–47 % and 76–146 % in presence of straw. Inoculation with azospirilla as such did satisfy 30 % of the N-requirements of plants, and straw amendment boosted effects of inoculation particularly in presence of moderate doses of N-fertilization.
