STUDY ON DIAZOTROPHIC AND IAA PRODUCING BACTERIA ISOLATED FROM DESERT SOIL SUBMIT AN APPLICATION FOR BIOFERTILIZER

摘要

Biofertilizers are an alternative to mineral fertilizers for increasing soilproductivity and plant growth in sustainable agriculture. The objective of this study wheat plantgrowth promoting by non symbiotic (Azotobacter spp.)Strains as biofertilizer on soil propertiesand seedling growth of wheat in soil, and the application treatments included the control (withoutbacteria inoculation), non symbiotic organism isolated saline desert soil in which studied soil allproperties. Checked nitrogen fixing activity, IAA producing activity and studied activity againstpesticide of all isolated and record results
