Response of two wheat cultivars to inoculation of Bacillus subtilis and Phosphorus fertilizer

Abstract

A pot experiment was conducted at College of Agriculture, University of Diyala during the season (2017-2018) In order to evaluate the efficiency of Bacillus subtilis plus phosphorus chemical fertilizer on two wheat cultivars (Ala and Audi). A factorial experiment was arranged with three replications of each treatment and two factors, the first include two wheat cultivars, the second factor includes three different levels from bio and chemical fertilizers. Results showed that application of bio fertilizers B. subtilis with a half dose of chemical fertilizer were superior significantly in Plant height and Number of branches 46.98, 65.68 cm and 3.87, 7.71 after 45 and 120 days respectively, Plant fresh weight 39.41 g, Plant dry weight 19.18 g, % Phosphor in plant 0.27% while Bio fertilizer was superior in Number of bacteria from other treatments reached 90.66×106. Ala cultivar was the best in traits of Plant height and Plant dry weight, whereas Audi cultivar was the best in traits of Number of branches, % Phosphor in plant and Number of bacteria.
