Abstract:

Application of biofertilizer, especially plant growth promoting rhizobacteria through integrating use by chemical fertilizer is the most important strategy for integrated plant nutrition in sustainable management of agro-ecosystems, their production increase by adequate input sustainable agriculture system. This experiment was factorial in randomized complete block design with four replications at Farming Research of Islamic Azad University of Gorgan. Treatments were different percent of biofertilizer Nitroxin (azospirillum bacteria and azotobacter), urea (content 46% nitrogen) inclusive nitrogen was supplied by Nitroxin: N1: the total amunt (100%) of nitrogen was supplied by urea (150 kg/ha), N2: 75% of total amont of  nitrogen was applied by urea (112 kg/ha)and 25% by Nitroxin (1 lit/150kg seed), N4: 25% of total amont of  nitrogen was applied by urea (75 kg/ha) and 75% by Nitroxin (1.5 lit/150 kg seed) and N5 total needed nitrogen was supplied by Nitroxin (2 lit/150 kg seed). The second treatment, wheat cultivar, consisted of Kouhdasht, N80-19 and N81-18. Nitroxin biofertilizer increased height, seed number in cluster, yield, leaf area and dry weight in different cycle of wheat growth. Nitroxin biofertilizer also increased leaf area and dry matter at ear emergence and milk development stage compared to urea usage.   Nitroxin biofertilizer can serve as a replacement for chemical fertilizer in wheat plant growth.
