Abstract

ABSTRACT The use of intercropping systems and beneficial microorganisms to improve the performance of crops constitutes a promising strategy. In this context, a pot experiment was conducted to evaluate the effects of intercropping and inoculation with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) on the performance of barley and alfalfa plants and soil health. Three inoculation treatments (for both monocropped and intercropped plants) and the control were used: (1) AMF-inoculated plants; (2) PGPR-inoculated plants; (3) AMF+PGPR co-inoculated plants. Combining intercropping and AMF+PGPR co-inoculation improved shoot and root dry weight by 167% and 300% in barley and by 712% and 617% in alfalfa, respectively, compared to the controls. Similarly, in barley intercropped and inoculated with AMF+PGPR, the number of grains per spike and the thousand-grain weight were enhanced by 124% and 122%, respectively. Applying intercropping and co-inoculation of AMF+PGPR increased the protein, total phenolic, and flavonoid contents of barley grains by 99%, 132%, and 343%, respectively. The contents of soil nitrogen and phosphorus were improved by 387% and 270% in barley soil and by 359% and 212% in alfalfa soil, respectively, compared to monocultures.

期刊介绍： rchives of Agronomy and Soil Science is a well-established journal that has been in publication for over fifty years. The Journal publishes papers over the entire range of agronomy and soil science. Manuscripts involved in developing and testing hypotheses to understand casual relationships in the following areas: plant nutrition fertilizers manure soil tillage soil biotechnology and ecophysiology amelioration irrigation and drainage plant production on arable and grass land agroclimatology landscape formation and environmental management in rural regions management of natural and created wetland ecosystems bio-geochemical processes soil-plant-microbe interactions and rhizosphere processes soil morphology, classification, monitoring, heterogeneity and scales reuse of waste waters and biosolids of agri-industrial origin in soil are especially encouraged. As well as original contributions, the Journal also publishes current reviews.
