【 摘 要 】

The effect of biofertilizers (inoculation with different bacterial isolates), foliar spraying with some micronutrients and their interaction on growth, physiological parameters and nutrients content of wheat plants grown on new reclaimed soil were studied. The growth parameters, some physiological parameters and nutrient contents of wheat plants were significantly increased by inoculating wheat grains with different bacteria as compared with un-inoculated (control). The highest values of all the mentioned parameters were obtained by usingAzospirillum brasilensefollowed by AzotabacterchroococcumandBacillus polymyxain decreasing order. Foliar spraying treatments significantly increased the growth parameters, physiological parameters as well as nutrients content of wheat plants as compared with control treatment. Highest values were obtained by using (Mn+Fe+Zn) treatment followed by Zn, Fe and Mn in decreasing order. Micronutrients in wheat plants differed as the foliar treatments were differed, so application of any micronutrient individually significantly increased its content andenhanced the content of other micronutrients in wheat. Used biofertilizers and foliar spraying with micronutrients significantly affected all the studied parameters of wheat plants, the highest were obtained by inoculating wheat grains withA.brasilenseand spraying the plants with (Mn+Fe+Zn) treatment, while the lowest values were attained by un-inoculated grains (control) and spraying the wheat plants with tap water (control). It can be concluded thatthe data collected proves that the use ofAzospirillum, azotobacterorBacillus, in combination with foliar application with micronutrients (Mn+Fe+Zn) can lead to higher wheat yield.
