The high yield depends on high dry matter production per unit area. Azotobacter bio-fertilizer experiment to investigate the effect on the index, total dry matter accumulation and Pishtaz and Chamran wheat cultivars in 2005 was conducted in the Faculty of Agriculture, Lorestan University. Experiment, a split-plot randomized complete blocks design with four replicates were tested. Treatments consisted of two main factors Chamran cultivars (V1) and Pishtaz (V2) and sub-agents include non-biological chemical fertilizer (NC), bio-fertilizer Azotobacter alone without the use of urea fertilizer (N0), 60 kg of urea fertilizer with Azotobacter bio-fertilizer (N1), 120 kilogram of urea fertilizer with Azotobacter bio-fertilizer (N2), Azotobacter bio-fertilizer consumption with 180 kilogram nitrogen (N3) respectively. Results showed that the dry matter accumulation during different Rshdgndm the leading figure of the figure is more flexible and thus Chamran manure dry matter production per unit area is greater. The dry matter accumulation in different fertilizer treatments also investigated the use Azotobacter + 120 kilogram per hectare urea fertilizer consumption in comparison with the positive and satisfactory results in the accumulation of dry matter than the other treatments showed that the treatment of Azotobacter + 180 kilogram per hectare was treated with urea, the number of minor differences in total dry matter accumulation followed the same trend in both treatments have, in the treatment of dry matter in grams per square meter was 185 days after planting to 2575.75 and treatment Azotobacter + 120 kilogram per hectare of urea in the same time, with little space to 2502.06 m was reached.
