Key words: Azotobacter, Bio-phosphate, Wheat.
In order to evaluate of influence of Azotobacter and Bio-phosphate fertilizers on yield and yield components of Wheat, an experiment was conducted during 2012-13 in rain-fed conditions of Noor Abad, Fars province, Iran. Factorial testing was carried out in a randomized complete block design (RCBD) in four replications. First factor included Azotobacter treatment at two levels (none Azotobacter and Azotobacter consumption “200 grams per hectare”) the second factor Bio-phosphate (none Bio-phosphate and Bio-phosphate consumption “100 kg per hectare”). After pedological testing, Seeds prepared from research centers and they were planted in the plots Designed. Measured traits include plant height, number of spikes per square meter, number of grains per spike, Thousand-seed weight, number of tillers on per shrub, biological yield and grain yield. The results of variance analysis showed that the interaction of Azotobacter and Bio-phosphate had significant effect on stem height, number of spikes per square meter, number of grains per spike and grain yield at the level 1%. The highest grain yield and biological performance was observed in investigated plant at N2P2 treatment (interaction of Azotobacter and Bio-phosphate). Based on our results, in order to increase biological yield and grain yield of rain-fed wheat, using of Azotobacter and Bio-phosphate is recommended for cultivation in areas that climatic conditions similar to NurAbad.
