Abstracts |
This study in central Japan was conducted to determine whether or not mycorrhizal colonization, and the growth of maize and oat in an Andosol field are affected by reduced tillage. Both crops were grown under 4 tillage combinations: continuous rotary tillage from previous season, no-tillage followed by rotary tillage, rotary tillage followed by no-tillage and continuous no-tillage from the previous season. The population of arbuscular mycorrhizal (AM) fungi was not significantly affected by the tillage treatments. The early-season colonization of AM fungi on maize roots was significantly stimulated by the no-tillage treatment, irrespective of the preceding tillage treatment. Although continuous no-tillage enhanced the growth of maize, it had no significant effects on the final yield. The tillage treatments had no significant effects on the colonization of AM fungi on oat roots or the growth of oat. |
