Abstract

Carried out research in the production unit of the pilot project for the cultivation of mushrooms / College of Agriculture / University of Tikrit, used the isolation of A. bisporus mushroom food, a strain of fungus A.bisporus B62 Dutch origin were also used bacterial isolation P. putida , To inoculated casing layer that attended, including 12 treatment of soils casing included , soil casing Top Terra Dutch origin (T1) and soil casing Pettmos German origin type SAB Substrate 1 (T2) and soil casing of local (a mixture of sand with Pettmos ratio of 1: 1) (T3) and 9 mixtures of different proportions of them with the use of ratios of Vermiculite and Hematite. Used the above mixture with or without the inoculate bacterial P. putida to become the number of treatment 24 treated with three replications to become the number of units and 72 experimental pilot unit. And used a design by CRD system two factors.to study its role the production of of A. bisporus. The most important results.: treatments made locally prepared soil casing (T3, T5, T11, T12) significantly affected the rate of increase in the length and diameter of the fungus compared to T1, T2 also achieved the overlapping use of the inoculated bacteria P. putida with soil casing with emotion, moral, And gave the use of the inoculate P. putida significant effect in increasing the rate of cap diameter and recorded treatment soils casing prepared locally T3, T4, T5, T7, TII, T12 in the thickness of the hat compared T1, T2 also achieved interaction inoculate and diversity of treatment soil casing note that this trait linked total production. increased early production of mushroom morally adding the inoculate bacterial Valley diversity hedging treatments influential mixed in the rate of early production reached the highest rate in 1935 and 1738 and 1614 g of T1 and T11 and T3, and gave interaction the highest significant effect reached in 2088 and 1909 and 1831 g of transactions T1 and T11 and T5 with the inoculate and these results reflected the values of total production and efficiency of biological. protein ratios which stood with the use of the inoculate 32.65%, also characterized the treatments T4 and T10 TT6 and the highest content was 35.5% and 34.29% and 34.38%, while it was not any significant effect in carbohydrate ratios
