Résumé de la publication

The attainment of the millennium for development objectives require to improve the productivity of major cultures like maize (Zea mays L.). The present study aimed to assess the potential of Glomus cubens, Rhizophagus intraradices and Funneliformis mosseae to improve the productivity of corn cultivated on reddish ferrous soil in Southern Benin. A block of nine treatments with four repetition completely randomized was installed. Plant height and diameter and leaf area are growth parameters measured. Grain yield and endomycorrhizal infection were also evaluated. The best growths and grain yield (2.33 t/ha and 2.12 t/ha) were obtained respectively with the plants treated with R. intraradices + 50% of NPK and G. cubens + 50% of NPK compared to the control plants (1.48 t/ha). Moreover, the great frequencies of mycorhization (44% and 32.25% were observed respectively on the plants treated with G. cubens + 50% of NPK and R. intraradices + 50% NPK. These results show that the respective combination of these two Arbuscular Mycorrhizal Fungi with 50% NPK can increase of 50% the seeds yield of corn compared to the seeds yield obtained with the control plants. In addition, G. Cubens and R. intraradices are active in the colonization of maize roots. Use of R. Intraradices or G. cubens in combination with 50% of NPK help to increase the corn productivity and to reduce of half the chemical fertilizer commonly used by corn farmers at Southern Benin.
