Abstract: oRGANIC farming is an advantageous agricultural system that enhances agro-ecosystem health,including biogeochemical cycles, biological activity and biodiversity in soils.
In this regard, pots and lyzemeter experiments were conducted to evaluate eight compost preparations, and to investigate the combined effect of compost- Azotobacter chroococcum on growth and yield of wheat (Triticum aestivum L.) Cv. Misr 2 under
different nitrogen levels (25, 50, 75 and 100% of full dose of nitrogen fertilizer). In pot experiment, application of compost treatment No. 8 (produced by mixture of rice straw
cattle dung and inoculated with Bacillus licheniformis and Bacillus sonorensis) attained the highest vegetative growth parameters at 46.3 cm plant height, 8.92 g plant fresh weight and 2.96 g dry weight of wheat plants at 30 days after sowing comparing with control. On the other hand, results in lyzemeter experiment showed that treatment No. 9
(50% of full dose of nitrogen fertilizer + 50% compost (pile 8) + inoculation with A.chroococcum), is the most effective treatment for enhancing growth dynamics, enzyme activity and microbial populations. Also, the highest data of biological yield, grain yield and straw yield were recorded 22.5, 8.64, and 13.92 ton ha-1, compared to traditional
N-fertilizer, respectively. Therefore, this study could establish the successive uses of cellulase producing microbes, B. licheniformis and B. sonorensis, and N -fixing bacteria A. chroococcum as friendly microorganisms to improve wheat production
