Evaluation of azospirillum, mycorrhiza and streptomyces efficiency with manure utilization in wheat by using 32P

In order to study the symbiosis relationships of Azosporillum bacteria, Mycorrhiza fungi, and Streptomyces from actinomycetes with the roots of wheat as biofertilizers that could provide plant nutrients and its protection, a research was conducted under greenhouse condition. Manure (dung) 3was used as biofortilizer. Interactions of the three mentioned microorganisms were studied using P. Factorial experiment in completely randomized design with three replications was used in which two levels of each microorganisms and manure (one with and one without using) were applied. Results showed that using Azospirillum, Mycrorhiza, and manure, individually, caused significant increase in plant height, tiller per plant, plant dry weight, and activity per plant. Also, manure increased stem diameter significantly. Results of threefold and fourfold interactions of experimental factors showed that utilization of Azospirilum and Mycorrhiza specially with manure increased most of the characters. A negative, antagonistic interactions between Mycorrhiza and Streptomyces was found. However, there was not anyʹ antagonistic interactions between Azospirillum and Streptomyces.
