APPLICATION OF CARBOXIN THIRAM FUNGICIDE AND AZOSPIRILLUM GENUS ON MINERALS NUTRIENT UPTAKE OF WHEAT PLANT

Background and Aim:Azospirillum bacteria increase plant growth by establishing an associative relationships with the plant in various ways, the ability to nitrogen fixation and biosynthesis of plant growth hormones that stimulate plant growth.Methods:Performing green house test, the effect of Carboxin thiram fungicide in 2 use (2 gr Carboxin thiram in 1000 gr wheat) and non-use levels on wheat plant (Chamran Cultivar) association relationship between five Azospirillum species (A. abrasilense, A.lipoferum, A. halopraeferens, A. irakense, A.sp), in two formulations (powder and liquied) separately, on uptake of K, P, Mn, Zn, Fe and Cu elements and also on Shoot Wet and Dry Weight and number of Tiller were studied.Results:The results showed that the interaction of Azospirillum bacteria formulations and fungicide, uptake of P and Mn elements, and on shoot dry weight (p <0.01) and shoot wet weight (p <0.05), were significant, so that at the level of use Fungicide, the highest uptake percentage of Mn and P in liquid A. brasilense treatment (3.27%), and powder A. lipoferum treatment (19.51%), respectively were obtained. Also the highest percentage of Shoot Wet and Dry Weight were shown in powder A.lipoferum (24.44%) and powder A. halopraeferense (48.4%) respectively than non-inoculated control treatmentConclusion:Therefore, a further study on the use of a mixture of these strains is recommended to increase the uptake capacity of all these elements and increase the yield of the test plant.
