Dynamics of wheat root colonization by arbuscular mycorrhizal fungi under contrasting soil tillage systems and its impact on grain yield

In this work, we investigated the effect of soil tillage farming system on variability arbuscular mycorrhizal fungi (AMF) root colonization a local durum wheat variety, conducted during five years experimental trial in semi-arid region eastern Algeria. No improved AMF symbiotic activity from fourth year testing with appearance high percentage arbuscules at tillering and grain filling stage. Compared to that, conventional was marked by observation vesicles especially filling. Despite inter-annual fluctuations, no average yield 20%. Multiple regressions analyses using stepwise selection method were made formulate an equation linking components specific each system.
