Abstract :
Present study was conducted for evaluation of the effect of vermicompost (VC) and mycorrhiza on growth and yield and biochemical traits of wheat under drought stress conditions in greenhouse. Factors include three levels of irrigation, three VC level (0, 3 and 6 percent) and application and non-application of mycorrhiza. Results of present study showed positive and significant impact of vermicompost and mycorrhiza inoculation on wheat growth traits under drought stress conditions. Also, According to results Highest grain yield by 4.22 ton/ha achieved in control level of drought stress and application 6 percent VC and mycorrhiza and lowest amount obtained in non-application of mycorrhiza and VC by 2.89 ton/ha. Results showed that application of vermicompost and mycorrhiza inoculation caused to increasing proline content in plant and consequently increase in plant resistance to drought conditions which was evident in wheat plant yield and yield components. Organic fertilizers due to long term impacts on soil properties, providing micro- and macro nutrients and maintenance of soil biological properties could be economic and compensate production cost of bio-fertilizers and so make possible continuous and optimal use of agricultural land possible.
