Evaluate several types of soils casing prepared locally in the production of mushroom Agaricusbisporus

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 casingPettmos 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 A. bisporus and evolution the spent as biofertilizer.The most important results: Treatment T1 increased the highest production rate amounted to 21.48 kg m-2 and recorded the transaction T2 lower rate of total production amounted to 14.04 kg m-2 and gave interaction withcasing soil inoculum and the highest production with T1 treatment with inoculum amounted to 22.66 kg m-2 better efficiency biological achieved 61.68% with the use of a inoculum, and has interaction withinoculum and better biological efficiency rate of 75.54% with T1 treatment using inoculum.The impact of the use of the inoculum in reducing the percentage of C / N in the middle reached 16.89 and nitrogen by 1.61% and outperformed T11 registered ratio C / N 16.46 and nitrogen ratio of 1.63%. And found to interaction with the inoculum treatment T5 best ratio C / N reached 16.32. Showed treatment T11 significant effect on the rate of the values of conductivity electrical amid depleted as it reached 8.22 DS m-1, and gave the overlap between the treatment T8 and the inoculumsignificantly affected, amounting to 8.69 Dessie Siemens m-1 8 and had no significant effect for treatment of T3 in pH values reaching the highest rate of 7.24. And decreased to reach 6.06 with treatment T8, and gave the interaction between T3 treatment and inoculum significant effect reaching the highest rate of 7.90.increased use of the inoculum proportion of phosphorus in the middle reaches 0.54%, and T4 treatment showed the highest rate of 0.40%, and was found to interaction with the inoculum T4 treatment significantly affected 0.52%. It also gave the treated soil coverage T12 significant effect to the middle of the potassium content 1.56% and gave the T12 overlap with the moral influence of the inoculum to reach 1.61%, the highest recorded transaction T6 significant effect on the rate of iron 0.442 mg L-1. T12 showed treatment had no significant effect in the middle depleted content of manganese and recorded a rate of 2.56 mg L-1,And gave interaction treatment T12 and the inoculum significant effect was 2.56 mg L-1. Showed treatment T6 significant effect on the rate of zinc amounted to 0.083 mg L-1, and found to interaction treatment T7 and inoculum significant effect amounted to 0.085 mg L-1 . significant effect of the use of the inoculums in the rate of content center depleted of copper, which reached 0.036 mg to Tr-1, T8 treatment also showed a significant effect amounted to 0.045 mg l -1 also gave interaction T8 treatment and inoculum significant effect amounted to 0.045 mg l -1
