چکیده انگلیسی
Arbuscular mycorrhizal fungal (AMF) colonization and nodulation of groundnut were examined in nine soils collected from subsistence farmers' fields in Zimbabwe. Nodule number, shoot dry weight, shoot N and P contents, and AMF colonization were assessed after 6 weeks growth. Both nodule number and AMF colonization differed by an order of magnitude among the nine soils. Soil available P explained almost all the variability in nodule number (r2Â =Â 0.98), but had no significant effect on percent AMF colonization. By adding P to one soil, nodule numbers increased four-fold resulting in a significantly higher N content in the shoots. Similar, but smaller, effects were obtained by increasing the abundance of AMF through an inoculation with Glomus intraradices, suggesting that nodulation in this soil was limited by AMF abundance and that the fungi could, to a limited extent, substitute for P fertilizer.
