Abstract
In order to evaluate the effects of planting date, genotype and Azetobacter on wheat, the experiment was conducted in Bardsir Agricultural Research station in 1358. Planting date was mentioned as main factor in three levels (15th of Mehr, 5th of Aban and 25th of Aban), Azetobacter in three levels and three different genotype of wheat including, C80-2, C80-4 and Alvand (control) were treated as Split factoriel in RCBD with three replication. The measured traits at harvesting time was, mean on spikelet per spike, plant height, Spike length, Number of tiller, straw weight, 1000 grain weight, grain protein, and grain yield. There is significant difference among different planting dates, also the interaction of Genotype× azetobactor was significant for yield, the highest yield was belonged to Alvand with inoculation with Azetobacter white C80-4 had showed the lowest yield without inculation. The interaetion of planting date × Genotype C80-2 was the best the in the 5th Aban white this line had the lowest yield on 25th Aban. At the whole experiment Alvand showed the highest yield with inoculation, at 5th Aban as planting date, while C80-4 had the lowest in 25 of Abab and without inoculation. According to the result of this research, Azetobacter as an useful biological fertilizer would be advisable, due to facilating the Application and Economic benefit, For the farmers. Also it is advised to the farmers for planting Alvand as a good variety, and also planting in 5th of Aban because of escape of temperature stress.
