Effect of Azospirillum inoculation on yield of field-grown wheat

Two cultivars of Triticum aestivum and T. turgidum were inoculated with bacteria of the genus Azospirillum in field experiments carried out in the Northern Negev and Bet Shean Valley. The results showed significant increases in yield of grain and foliage. There were significant increases in the number of fertile tillers per unit area and in the nitrogen yield. The possible mechanisms by which Azospirillum inoculation benefited wheat and other crops are discussed.
