Abstract

This study was conducted in the project of organic fertilizers in Shatrah , Thi-Qar Governorate , Iraq to realize the effects of bacterial pollution by A. brasilanse with and with out nitrogen fertilization on the growth and production of wheat Triticum aestivium L. . The nitrogen fertilizer levels were (A.lipoferum) and the bacterial pollutions were (A.brasilense) . The RCBD design was used with four repetitions .The results showed that the treatment of bacterial pollution A1 surpassed significantly on the other treatments in length of plants , number of tillers , spike length , number of spikes per square meter, number of grain in the spike , and the yield of grain per Donam , it reached to 1140.28 kg / Donam , so the treatment of fertilizer level ( kg / Donam ) surpassed on the others fertilizer levels in length of plants , number of tillers , spike length , number of spikes per square meter, number of grain in the spike , and the yield of grain per Donam . In addition to that , the results showed a presence of interaction between the effect of bacterial pollution treatment A1 with the fertilization level ( C3 ) and surpassed significantly for whole studied characteristics and gave high mean production reached to 1229 .20 kg of grain per Donam .
