Abstract

The research aimed to determine the role of different mycorrhizae species and two phosphorus doses on bell pepper growth and P nutrient uptake under field conditions. The experiment was carried out, in the Menzilat soil series, in the Research Area of the Faculty of Agriculture, Department of Soil, Adana-Turkey, for two successive years. Bell pepper seedlings inoculated with Glomus mosseae and G. etunicatum mycorrhiza species. Pepper seedlings were propagated in 50 × 70 × 30 cm wooden crates in sterile medium by inoculation with control (nonmycorrhizal), G. mosseae and G. etunicatum mycorrhiza species with (P1= 80 kg P₂O₅/ha) and without (P0= 0 kg P₂O₅/ha) P fertilizer. At four leaves stage seedlings were transplanted. Twenty-one plants were maintained at each plot. First-year results indicated that mycorrhiza inoculation significantly increased yield as compared to t control plants Addition of phosphorus improved yield regardless of mycorrhiza inoculation. Second-year results showed the positive impact of mycorrhiza inoculation by increasing bell pepper yield. A 100% yield increase was observed in plots inoculated with mycorrhiza but no application of phosphorus. Mycorrhiza root infection rate was found higher in plants inoculated with G. mosseae and G. etunicatum. Both mycorrhiza species showed behaviors according to the findings. During the first-year mycorrhiza inoculation had not much influence on the %P content of the bell pepper plant. Mycorrhizae inoculation significantly increased plant tissue Zn concentration. The dependence of the pepper plant on mycorrhiza was calculated and it was determined that the dependence of the bell pepper plant on mycorrhiza increased up to 57% at low phosphorus.
